❤ Thank you ma for such a simplified lecture ❤ I learnt that BioRisk characterization is the determining the process of livelihood and consequences of a well defined risk within a risk assessment Risk assessment is an analytical procedure designed to characterize biological risk facility or other types of operation dealing with potential toxins Also assessment covers the BIOSAFETY and BIOSECURITY risk assessment which says that BIORISK ASSESSMENT is an analytical procedure designed to characterize safety risk in the lab same with BIOSECURITY but its designed to characterize security risk in a Laboratory Things that affect biorisk assessment are 1. Method of waste disposal 2. Duration of exposure 3. Laboratory design Risk assessment for the identification of HAZARD AND THREATS HAZARD: is something that is potential to cause harm while THREAT: is someone who intends to cause harm
Thank you ma, for this great lecture on Bio risk characterization and evaluation. I understood that a biological risk assessment is an analytical procedure designed to characterize biological risks in a facility, laboratory or unit within it, or other type of operation dealing with potential pathogens or toxins. It comprise of Biosafety risk assessment and Biosecurity risk assessment. Biosafety risk assessment is an analytical procedure designed to characterize safety risks in a laboratory. While Biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory. We need biological risk assessment to allow a facility, laboratory, or other operation to determine the relative level of risk it's different activities pose, and helps guide risk mitigation decisions so that these are targeted to the most important risks. It's objective is that the support the selection of appropriate laboratory biosafety and laboratory biosecurity risk mitigation measures to reduce likelihood and consequences of breaking into the laboratory, injuries or falling ill. Factors relevant to biosafety are: - Method of waste disposal - Duration of exposure - Virulence - Laboratory design - Route of exposure Factors relevant to biosecurity are: - Motive - Location of laboratory - Security of the agent - Accessibility - Access control - Opportunity Factors relevant to both are: - Training/staff competency - Infrastructure/equipment - Adherence to safety measures Risk characterization is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment. The first step in a risk assessment is the identification of hazards and threats based upon the situation. The next step is the characterization of the hazards and the threats based upon the likelihood and consequences. For biosafety risks, the hazards the biological material worked with in the lab. While for biosecurity risks, the threat is an adversary aiming to acquire the biological material and use it to cause harm. Also a hazard or threat cannot in itself pose a risk without a specific situation. Conversely, a situation also does not represent a risk without a hazard or threat. Both a changing hazard or threat and a changing situation will independently alter the scenario being assessed and the change the risk. Another consideration in characterizing risk is the concept of relative risk. Relative risk is the value of one particular risk( in terms of likelihood and consequences) in the context of another risk. Risk is relative due to the fact factors that go into determining the risk are not absolute. It is important that risk characterization process be as robust as possible. - Comparability is the ability to trust the accuracy of differences between assessment due to similarities in their bases, assumptions, procedure and protocols. - Repeatability is the ability to conduct the same process in the same way for the same hazard or threat and situation over a period of time or for different hazards, threat and situations at the same time. A robust risk characterization process will generate similar results when assessing similar situation, no matter who is following the methodology, where the characterization is being conducted and when it's occuring. One available to aid in the laboratory risk assessment is the Biosafety and Biosecurity RAM( BioRAM ). BioRAM is a computerized risk assessment tool developed by Sandra national laboratory in partnership with the international community to facilitate laboratory biosafety and biosecurity risk assessments by simplifying risk characterization. BioRAM uses one of several possible risk assessment methodology. Risk evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risks. It is the process of determining subjections, whether a is high or low, and whether it's acceptable or not. There is no systematic way of evaluating risk or to determine risk acceptability. This will depend on the perception of individual, institution and the community.
The Breakdown of bio risk characterization and evaluation was really helpful. Identifying biological agents, assessing exposure, and evaluating potential impacts were well explained. The practical insights on consequence analysis and likelihood estimation for prioritizing risks. Your emphasis on continuous monitoring and adapting strategies highlighted the importance of staying proactive. This video is fantastic resources for anyone looking to understand biorisk management Through these lectures i was able to understand that bio risk assessment is a careful procedure made to characterize biological risks in lab
Thank you so much Prof. Again for delivering an awesome lecture on *Introduction to Risk Management Performance* To summarize the lecture: # The Biorisk Pyramid The goal of biorisk management is to identify and reduce risks before they evolve into near misses or incidents. The pyramid consists of: 1. Harmful incidents (e.g., laboratory-acquired infections) 2. Near misses (e.g., improper PPE use) 3. Unsafe and insecure conditions (e.g., inadequate biorisk training) # Performance in Biorisk Management Performance refers to how well a biorisk management system functions to manage or minimize biorisk. Characteristics of BRM system performance: - Result of all activities and efforts of all people in a facility - Actual performance may not match planned levels - Performance measurement assesses differences and changes over time # Benefits of BRM Performance 1. Determines which parts of the BRM system meet stated goals or benchmarks 2. Provides a demonstrable record of system performance 3. Supports facility certification/accreditation 4. Identifies areas for improvement 5. Provides assurance that risk is acceptable 6. Facilitates maintenance and sustainability of the system 7. Can save money and time 8. Helps prevent incidents # Key Points - Mitigation is not perfect; implementing one mitigation measure alone has weaknesses - Multiple mitigation measures can reduce risk likelihood but not eliminate it - Performance measurement is crucial to assess BRM system effectiveness # Performance Scenario A waste transport disposal company employee contracted tuberculosis from biohazard bags from a local TB reference laboratory. Investigation revealed performance issues, including missing records and inadequate storage of autoclave printer records. # Potential Measurement Methods 1. Audits and inspections 2. Performance indicators 3. Observations 4. Interviews 5. Surveys and questionnaires
THANK YOU MA FOR SUCH A SIMPLIFIED AND WELL EXPLAINED LECTURE. I LEARNT SO MUCH. WHAT IS RISK:Risk is the likehood of an undesirable event happening that involves a specific hazard or threat and has consequences. I learnt that BIORISK CHARACTERIZATION is the process of determing the likehood and consequences of a particular well defined risk within a risk assessment. The lesson also showed that there are certain parameters of likehood and consequences of which BIORISK CHARACTERIZATION helps to determine route of exposure. I also learnt that BIORISK ASSESSMENT which is an analytical procedure designed to characterize biological risks in a laboratory with potential pathogens,to determine the likelihood and consequences.The risk is characterized as BIO SAFETY RISK ASSESSMENT and BIO SECURITY RISK ASSESSMENT. Also I learnt why we need bio risk assessment because it allows a laboratory to determine the RELATIVE level of risk it's different activities pose. The difference between HAZARD and THREAT is that hazard is something that has the potential to cause harm whereas threat is someone that has an intent of causing harm RISK EVALUATION: This is the process of determining, subjectively, whether a risk is high or low and whether its acceptable or not.The evaluation of risk is highly related to the concept of RISK ACCEPTANCE. There is no systematic way of evaluating risk or to determine risk acceptability.This will depend on the perception of individuals, institutions and the community. Thank you so much ma.

SUMMARY ON BIORISK CHARACTERIZATION AND EVALUATION A biological risk assessment is an analytical procedure designed to characterize biological risk in a facility, laboratory or unit within it. Biosafety risk assessment is an analytical procedure designed to characterize safety risks in a laboratory. Biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory. A biological risk assessment allows a facility or laboratory to determine the relative level of risk it's activities poses and helps guide risk Mitigation decision so that these are targeted to the most important risk. *Risk assessment* is a process that characterize a particular situation in order to determine the likelihood and consequences of a certain adverse event( Risk Characterization) and supports decision making regarding the acceptability of the risk ( Risk Evaluation). *Risk Characterization* is the actual process of determining the likelihood and consequences of a particular risk within a Risk Assessment. The first step in a rush assessment is the *Identification* of hazard and threats based on the situation. The next step is the *Characterization* of hazards and threats based on likelihood and consequences. A *Relative Risks* is the value of one particular risk( in terms I'd likelihood and consequences) in the context of another risk. Understanding the relative risk associated with different situations or by implementing different risk mitigation strategies is important for the overall process of Characterizing risk. It is important that the risk Characterization process be as Robust as possible so that it will generate similar results when assessing similar situation and where the Characterization is occuring. *BioRAM*(Biosafety and Biosecurity RAM) is a computerized risk assessment tool developed by *Sandia National Laboratory* in partnership with *International Community* to facilitate lab biosafety and biosecurity risk assessment by simplifying risk Characterization. The BioRAM tool helps determine the relative risk levels in a comparable and repeatable way. *Risk Evaluation* is a crucial intermediary step between risk Characterization and taking active steps towards mitigation risk. The evaluation of risk is highly related to the concept of *Risk acceptance* . There is no systematic way of evaluating risk or to determine risk acceptability. This will depend on the perception of individuals, institution and communities.

This video class was highly insightful! The lecture on bio-risk characterization and evaluation provided a clear understanding of the systematic process for identifying, assessing, and prioritizing biological risks. A key takeaway for me was the distinction between hazard identification and risk characterization, which highlighted the importance of considering both the likelihood and potential impact of biological threats. The use of real-world examples and case studies made the complexities of bio-risk evaluation more relatable and underscored the critical need for continuous monitoring and review.
BIO RISK CHARACTERIZATION Bio risk characterization help us to evaluate route exposure, communicability, incubation time, and infection disease. I also learn how to identify and characterize those risk that are rising in the laboratory. I also learnt that BIO RISK EVALUATION and CHARACTERIZATION modifies pathogens, toxins and genetic materials, it also expose biological agent that can cause gems. Factors that drive different in capabilities between individuals and community are 1. Community awareness, norms, and values. 2. individuals Reputation and believe system 3. Institution Rules, legal issues, policies. BIO RAM Biosecurity and Bio safety is a computerised risk assessment tool developed for laboratory safety and bio security risk assessment.

Thank you, prof, for this great lecture. I learned about biological risk assessment and its connection to biosafety and biosecurity. I also learned that risk assessment is a process that helps us understand a situation to determine the likelihood and impact of an adverse event, and guides decisions about whether the risk is acceptable. I took note of the strategy for risk assessment, which includes selecting the right biosafety and biosecurity measures to reduce the chances and impact of injuries, etc. I also learned the steps for biorisk assessment, factors for biosecurity and biosafety, and what is needed for both. Risk characterization is the process of determining the likelihood and impact of a specific risk during risk assessment. The first step in risk characterization is identifying hazards and threats. I also learned about risk characterization in biosafety and biosecurity, and how it should be as thorough as possible. BioRAM is a tool used for lab risk assessment. It helps measure relative risk levels in a consistent and repeatable way. Lastly, I noted the difference between risk aversion and risk tolerance, as well as likelihood and consequences of risk, and their graphical representations. Lastly, I learned about the difference between risk aversion and risk tolerance, as well as the likelihood and consequences of risks, along with how they are represented graphically.
Thank you prof. for the lecture. In this video I learnt about Biorisk characterization and evaluation. Biorisk characterization in biosafety essential for accessing exposure routes, communicability, incubation periods and infectious diseases. Through this process, I got to understand the identification and accessment of emerging biological risks in laboratory settings.. - Risk evaluation -: Is the process of determining, subjectively, whether a risk is high or low and whether it is acceptable or not. The evaluation of risk is highly related to the concept of risk acceptance. - The varying abilities of individuals and communities to manage these risks are influenced by several factors like: - 1). Personal beliefs and reputation - 2). Influence of institutional regulations, legal standards and policies. - 3). The awareness, Norma and values present within the community. To add to this, BIO RAM is a digital toolused for conducting comprehensive biosecurity and biosafety risk assessments in laboratory environments.
Thank you ma for this lecture on bio risk characterization and evaluation this lecture made me to understand that biological risk assessment is an analytical procedure designed to characterized biological risk in a laboratory, facility or unit and other type of operation dealing with potential pathogens or toxins.and it comprises of biosafety risk assessment and biosecurity risk assessment. And below are the consequences of breaking into the laboratory, falling I'll or injury Factors relevant to biosafety are: # laboratory design # route of exposure # duration of exposure # virulence Factors relevant to biosecurity are: # motive # accessibility # security of agent # location of laboratory # access control Factors relevant to both are # adherence to safety measures # training # infrastructure/equipment Risk evaluation is a crucial intermediate step between risk characterization and taking active step towards mitigating risk.it is the process of determining subjections, whether is high or low and whether it's acceptable or not
Thanks Ma for this wonderful lecture, In this lecture I learnt that biorisk characterization is the process of determining the likelihood and consequences of a particular risk within a risk assessment and the first step in ris assessment is the identification of(i )Hazards and (ii) Threats based on the situation. I also understand that Risk evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risk. And in characterizing risk under biosafety you have to adhere to; 1.The use of PPE can lower the likelihood of exposure 2.Vaccines can lower the consequences of exposure while under biosafety 3.The use of physical barriers aids in lowering the likelihood of theft 4.The availability of therapeutics can lower the consequences of Malicious release
Thanks so much mar for the wonderful lecture, I learnt that: Biorisk characterization identifies the likelihood and consequences of biological risks through systematic assessment. Key Areas of Risk Assessment: Biosafety: Ensures lab safety by managing hazards (e.g., toxins, pathogens). Biosecurity: Focuses on preventing unauthorized access or misuse of biological materials. Factors Influencing Biorisk: 1. Waste disposal methods. 2. Exposure duration. 3. Laboratory design Hazards vs. Threats: Hazard: A potential source of harm. Threat: Intentional actions to cause harm. Effective risk management ensures safety and security in biological operations.

WHY WE NEED A BIOLOGICAL RISK ASSESSMENT we need it because it follows a facility lab or other operation to determine the relative level of risk It’s different activities pose and helps to guide risk mitigation decisions so that these are targeted to the most important risks. RISK ASSESSMENT MANAGER is a process that characterizes a particular situation in order to determine the likelihood and consequences of a certain adverse event ( risk characterization) and support decision making regarding the acceptability of the risk (risk evaluation) THE OBJECTIVE OR RISK ASSESSMENT IS TO SUPPORT THE SELECTION OF APPROPRIATE LAB BIOSAFETY AND LAB BIO SECURITY RISK MITIGATION MEASURES TO REDUCE LIKELIHOOD AND CONSEQUENCES OF SOMEBODY BREAKING INTO THE LAB TO TAKE THOSE HIGHLY PATHOGENIC MATERIALS FACTORS THAT SHOULD BE CONSIDERED IN A LAB BIOSAFETY OR BIOSECURITY ASSESSMENT Method of waste disposal Virulence Lab design Duration of exposure BIO SECURITY FACTORS Motive Location of laboratory Security of the agent accessibility For biosafety risks,the hazard is the biological material worked with in the lab BIORISK helps student, lab staff, management and community health centers know the level of risks involved and the consequences in order to keep them and the world at large Risk assessment for the identification of hazard and threats HAZARDS; A potential cause of harm Threat; is the intentional actions to cause harm Effective risk manager ; ensures safety and security in biological operations Thank you ma
This is one of the best lectures I’ve ever watched by Dr. Iya Eze Bassey, an associate professor of chemical pathology at the University of Calabar I appreciate the effort you put in to make this lecture as understandable as possible. Bio risk management is a system of processes to control safety and security risks associated with handling biological agents and toxins. This lecture also explains the importance of having a good bio risk management system in place, as it can help to reduce the risk of accidents and injuries. You then go on to discuss the different components of a bio risk management system, including assessment, mitigation, and performance. There’s also some examples of how a bio risk management system can be implemented in a laboratory setting. In a nutshell Risk is the likelihood of an undesirable event happening that involves a specific hazard or threat and has consequences. Bio risk management is a system of processes to control safety and security risks associated with handling biological agents and toxins." Bio risk management is important because it can help to reduce the risk of accidents and injuries. This is a well explained lecture on Bio risk characterization and evaluation
Thank you for this simplified lecture. Through this lecture,I have learnt that Bio risk characterization is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment. In characterizing risk under biosafety you have to adhere to this; -The use of PPE can lower the likelihood of exposure. Risk evaluation is the process of determining subjectively whether a risk is high or low,and it is hugely related to the concept of risk acceptable.It is also a crucial intermediary step between risk characterization and taking active steps towatds mitigating risk. Note:It is important to note that precise location of the risk tolerance curve on the graph is fact arbitary and it's the essence of risk evaluation.
Thank you ma for this wonderful lecture. Below is the summary of what i learnt Risk is the likelihood of an undesirable event to happen which involves a specific hazard or threat that has consequences. Risk of working in a lab with biological materials include: Infections,injuries,air pollution,disabilities,other health hazards and death. Futhermore Bio-safety risk + Bio-security risk equals Bio risk. Biorisk is the risk associated with biological materials in the laboratory. Bio safety addresses the unintentional exposure to bio hazards ensuring protection and general safety. Bio security defends against intentional theft or misuse of biological agents. Measures for bio-safety: Engineering controls,good laboratory work pratices,personal protective equipment (PPE) and practices and procedures. Measures for bio security: Doors with locks,biometrics,information security,alarms etc. Key component of bio risk management: 1.)Bio risk assessment 2.)Bio risk mitigation 3.)Performance It is called the AMP model. Bio risk assessment is the process of identifying hazards and evaluating risk. Bio mitigation is the action or control measures to reduce risk associated with biological materials. Performance is the simply the implementation of the entire bio risk management system. Biorisk management system is a set of system that is used for reducing safety and security risk. Advantages of good management system: 1.)condusive and safe environment 2.) Enhanced organizational performance et
Thank you ma'am the lecture was very interesting I learnt that, Biorisk characterization and evaluation are critical components of biorisk management. Here's an overview: *Biorisk Characterization* Biorisk characterization involves identifying and describing the biological agents, toxins, or other hazardous materials that could pose a risk to humans, animals, or the environment. *Factors to Consider* 1. Agent characteristics: Pathogenicity, virulence, infectivity, and toxicity. 2. Route of exposure: Inhalation, ingestion, skin contact, or injection. 3. Dose-response relationship: The relationship between the dose of the agent and the resulting harm. 4. Stability and persistence: The agent's ability to survive and remain infectious outside of a host. *Biorisk Evaluation* Biorisk evaluation involves assessing the likelihood and potential impact of a biorisk event. *Risk Assessment Methodologies* 1. Qualitative risk assessment: A subjective evaluation of the risk based on expert judgment. 2. Quantitative risk assessment: A numerical evaluation of the risk based on statistical models and data. 3. Semi-quantitative risk assessment: A combination of qualitative and quantitative approaches. *Risk Evaluation Matrix* A risk evaluation matrix is a tool used to evaluate the likelihood and potential impact of a biorisk event. The matrix typically consists of a grid with likelihood on one axis and impact on the other. *Risk Categorization* Based on the risk evaluation, biorisks can be categorized into different levels of risk, such as: 1. Low risk: Unlikely to occur and with minimal impact. 2. Moderate risk: Possible to occur and with moderate impact. 3. High risk: Likely to occur and with significant impact. 4. Extremely high risk: Almost certain to occur and with catastrophic impact. By characterizing and evaluating biorisks, organizations can develop effective strategies to mitigate and manage these risks, ensuring the safety and security of their personnel, facilities, and the environment.
Thank you very much for this lecture I learnt that risk is a likehood of an undesirable event happening that involves a specific hazard or threats and has consequences And I learnt that bio risk characterization is the process of determining the likelihood and consequence of a particular well defined within a week's assessment. The lesson also showed that they are certain parameters of likelihood and consequence of which bio risk characterization helps to determine root of exposure. Also I learnt why we need bio risk assessment. Because it allows a laboratory to determine the relative level of risk it's different activities pose. The difference between hazard and threat is that hazard is something that has the potential to cause harm whereas threat it's someone that has a intent of causing harm. Overall risk evaluation plays a vital role in ensuring that risk are understood and appropriately managed contributing to safer environment in various context from healthcare to environmental policy With all these I've got to get a clear vision on what I learnt to the area thank you very much ma god bless🙏
Thank you so much ma for this wonderful lecture It has been said that a biological risk assessment is an analytical procedure designed to characterize biological risk in the laboratory facility or unit dealing with potential pathogens or toxins. In other words, it is designed to characterize the security risk in the laboratory. Why do we need bio-risk assessment? It allows a facility or laboratory to determine the relative level of risk, It helps to guide risk mitigation RISK:also said to be the likelihood of undesirable event that occurs resulting to injury,death, hazard and damage etc Bio-risk characterization an evaluation also involves assessing the potential risk associated with biological agents or materials. This process is involved identifying hazards evaluating the likelihood of exposure and determining the consequences of such exposure. The key points of bio-risk include understanding the nature of biological agents,it's pathogenity and the routes or transmission.Evaluation involves assessing the impaction on human health and the environment and biosecurity measures. Note:the term HAZARD is used in biosafety while threat is used in biosecurity
Thanks again Dr for the information lecture, its really enlightening . WHAT IS RISK:Risk is the likehood of an undesirable event happening that involves a specific hazard or threat and has consequences. I learnt that BIORISK CHARACTERIZATION is the process of determing the likehood and consequences of a particular well defined risk within a risk assessment. The lesson also showed that there are certain parameters of likehood and consequences of which BIORISK CHARACTERIZATION helps to determine route of exposure. I also learnt that BIORISK ASSESSMENT which is an analytical procedure designed to characterize biological risks in a laboratory with potential pathogens,to determine the likelihood and consequences. The risk is characterized as BIO SAFETY RISK ASSESSMENT and BIO SECURITY RISK ASSESSMENT. Also I learnt why we need bio risk assessment because it allows a laboratory to determine the RELATIVE level of risk it's different activities pose. The difference between HAZARD and THREAT is that hazard is something that has the potential to cause harm whereas threat is someone that has an intent of causing harm RISK EVALUATION: This is the process of determining, subjectively, whether a risk is high or low and whether its acceptable or not. The evaluation of risk is highly related to the concept of RISK ACCEPTANCE. There is no systematic way of evaluating risk or to determine risk acceptability. This will depend on the perception of individuals, institutions and the community. Thank you so much ma.

Thank you ma for this insightful lecture. Biorisk evaluation and characterization is an analytical procedure that deals with recognizing the level of a biological risk and the likelihood of a potential hazard or threat including the consequences associated with such risk either in a laboratory facility or unit. Factors to consider when evaluating risk include; 1. Biorisk factors( method of disposal, duration of exposure, lab design and route of exposure. 2.

Let me stop here before I end up using all the words to express myself. Thank you again ma. With happiness in my soul, I have learnt yet another wonderful lecture in which I will never forget. I will state down below what I have learned; - Bio-Risk Characterization: - Definition: The process of identifying and describing the characteristics of a biological agent or material that may pose a risk to humans, animals, or the environment. - Goals: - Identify the biological agent or material. - Determine its properties and characteristics. - Assess its potential to cause harm. - Steps: 1. Agent identification. 2. Literature review. 3. Physical and chemical characterization. 4. Biological characterization (e.g., infectivity, toxicity). 5. Risk group classification. BIORAM Tool: - A computerized risk assessment tool by Sandia National Laboratories, developed to simplify biosafety and biosecurity risk assessment. - Evaluation of Risk: - No standardized method due to differences among individuals, institutions, and communities, impacting risk levels and acceptability. - Risk Concepts: - Understanding the differences between - Risk Adverse & Risk Tolerance, Likelihood Adverse & Consequence Adverse, and their graphical representation. Thank you so so much Dr. Iya Eze Bassey
Another fine lecture yet again, thank you for breaking down In summary, I learned that: * Biological risk assessment is a process to identify, evaluate, and control biological hazards. * It helps determine the potential risks associated with working with biological materials. * Key factors influencing biological risk include the nature of the biological agent, the potential for exposure, and the severity of the potential consequences. * The assessment process involves characterizing the hazard, assessing the likelihood and consequences of exposure, and evaluating the overall risk. * Effective risk mitigation strategies can be implemented based on the assessment findings. * Best practices for biological risk assessment include using a robust and repeatable process, considering the relative risk of different exposures, and communicating the results to stakeholders.
Thank you Ma for the lecture, I understood that: A biological risk assessment is an analytical procedure designed to characterize biological risk in a facility, laboratory or unit within it. Biosafety risk assessment is an analytical procedure designed to characterize safety risks in a laboratory. Biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory. Why we do Biological Risk Assessment: 1.It helps a Laboratory or facility to determine the relative level of risk its different activities poses and helps guide risk mitigation decisions. Risk Characterization: is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment. The BioRAM tool helps determine the relative risk levels in a comparable and repeatable way.
The objective of this lessons is to understand the risk characterization and evaluation processes within biological risk assessment. NOTE: when working in the laboratory you work with a lot of risk. So it's key to understand this concept . Risk is the likelihood of an undesirable event happening, that involves a specific hazard or threat and has consequences. Biological risk assessment allows a facility, laboratory, or other operations to determine the relative level of its risk different activities pose, and helps guide risk mitigation decisions so that these are targeted to most important risks. Risk characterization: Identification: identify biological agents that pose risks. Assessment: determine the likelihood and extent exposure to biological agents. Risk evaluation: calculate the likelihood and potential impact of side effects. Risk comparison: compare the estimated risk to set standard. Thanks ma'am for your time and effort
Thank you very much ma for this wonderful lecture With this lecture I have understood the crucial aspect of evaluating biological risk .In total summary biorisk characteriszation and evaluation involves 1 identifying and assessing biological risk. 2 Determining the likelihood and potential impact on risk. 3 Evaluating the effectiveness mitigation strategies 4 Monitoring and reviewing biorisk management performance With this explanation I now understand how to evaluate biological risk and development effective mitigation strategies
Thank you so much ma for this lecture In summary I have learnt that Bio risk mitigation involves strategies and measures implementation to prevent reduce or control risks associated with biological agents or toxins in research healthcare and other settings. The five categories of mitigation control methods include. 1 Elimination and substitution. 2 Engineering control. 3 Administrative control. 4 Practices and procedures. 5 Personal protective equipment ( PPE ) Bio risk mitigation strategies involve biosafety and biosecurity measures to prevent accidental or intentional exposure to hazardous biological agents or toxins . In conclusion the aim of biorisk management is to prevent biological accident, minimize the spread of disease and maintain safe materials for work
The Breakdown of bio risk characterization and evaluation was really helpful. Identifying biological agents, assessing exposure, and evaluating potential impacts were well explained. Bio risk characterization help us to evaluate route exposure, communicability, incubation time, and infection disease. I also learnt that BIO RISK EVALUATION and CHARACTERIZATION modifies pathogens, toxins and genetic materials, it also expose biological agent that can cause gems. There are factors that drive different in capabilities between individuals and community are 1. Community awareness, norms, and values. 2. individuals reputation and believe system 3. Institution rules, legal issues, policies. Through these lectures i was able to understand that bio risk assessment is a careful procedure made to characterize biological risks in lab
Thanks once again ma’am as it gets more clearer as we advance in each lessons. IN SUMMARY; BIO Risk characterization and Evaluation is the process of assessing the potential risk associated with biological agents such as pathogen, toxins and genetically modified organisms. it involves identifying hazard,threat and vulnerabilities determine the likelihood and potential impact of adverse events Hazard refers to the intention of biological agents that can cause germs , while threat refer to the intention use these agent for malicious purpose. BIO RAM (biological risk assessment and management) is a frame work used to guide the very process considering factors such as exposure routes and mitigation strategies What factors might drive different in risk capabilities between individuals , institution and communities Institution ---funding, reputation, belief system Institution ---legal issues,polices, rules and regulations Community factor ---community awareness,norms ,and values Risk assessment: This a process that characterize a particular situation in order to determine the likelihood and consequences of a certain adverse event( Risk Characterization) and supports decision making regarding the acceptability of the risk ( Risk Evaluation). Risk Characterization: It is the actual process of determining the likelihood and consequences of a particular risk within a Risk Assessment. The first step in a rush assessment is the Identification of hazard and threats based on the situation. The next step is the Characterization of hazards and threats based on likelihood and consequences. A Relative Risks: This is the value of one particular risk( in terms I'd likelihood and consequences) in the context of another risk. Understanding the relative risk associated with different situations or by implementing different risk mitigation strategies is important for the overall process of Characterizing risk. One further point i noted from the video is that It is important that the risk Characterization process, should be as Robust as possible so that it will generate similar results when assessing similar situation and where the Characterization is occurring. Bio RAM also known as Bio safety and Bio security RAM is a computerized risk assessment tool developed by Sandia National Laboratory in partnership with International Community to facilitate lab bio safety and bio security risk assessment by simplifying risk Characterization. The Bio RAM tool helps determine the relative risk levels in a comparable and repeatable way. Risk Evaluation is a crucial intermediary step between risk Characterization and taking active steps towards mitigation risk. The evaluation of risk is highly related to the concept of Risk acceptance . There is no systematic way of evaluating risk or to determine risk acceptability. This will depend on the perception of individuals, institution and communities. Am grateful for this shared knowledge. I enjoyed the tiger scenerio you used, your the best.
Thank you Ma for the detailed explanation. Here is what I learnt from this lecture: Risk characterization in biosafety is essential for assessing exposure routes, communicability, incubation periods, and infectious diseases. Through this process, I have gained an understanding of how to identify and assess emerging biological risks in laboratory settings. It also involves evaluating and modifying pathogens, toxins, and genetic materials, which can expose biological agents that may pose serious health risks. The varying abilities of individuals and communities to manage these risks are influenced by several factors: 1) the awareness, norms, and values present within the community 2) personal beliefs and reputations, and 3) the influence of institutional regulations, legal standards, and policies. Additionally, BIO RAM is a digital tool used for conducting comprehensive biosecurity and biosafety risk assessments in laboratory environments.
Thank you mar for the wonderful lecture. I learned about biorisk characterization and evaluation. Where you defined the following terms: Biorisk assessment: it is an analytical procedure designed to characterize biological risk in a facility, laboratory or unit within it, or other types of operations dealing with potential pathogens or toxins. Under which you elaborated on; Biosecrity risk assessment which is an analytical procedure designed to characterize security risk in the laboratory. Biosafety risk assessment which is an analytical procedure designed to characterize safety risk in the laboratory. I learned that biological risk assessment enables a facility, lab, or other operations to determine the relative level of risk its different activities pose, and help guide risk mitigation decisions so that these are targeted to the most important risk. Risk it is the likelihood of an undesirable event happening that involves a specific hazard or threats and their consequences. Risk assessment is the process and procedure that characterize a particular situation in order to determine the likelihood and consequences of a certain adverse avent ( risk characterization) and support decisions regarding the acceptablility of the risk . Risk characterization is the actual likelihood of determining the likelihood and consequences of a particular risk within a risk assessment. Risk evaluation is the process of determining subjectively weather a risk is high or low, and weather its acceptable (proceed with work) or not(leading to implementing risk mitigation measures).
Thank you Dr. for the wonderful lecture. Biorisk Evaluation and characterization is determining the process of livelihood and consequences of a well defined risk within a risk assessment is an analytical procedure designed to characterize biological risk facility or other types of operation dealing with potential toxins, also the assessment covers the biosafety and biosecurity assessment. factors that affect biorisk assessment method of waste disposal duration of exposure laboratory design risk evaluation is the process of determining subjectively whether a risk is high or low and acceptable or not. the evaluation of risk is highly related to the concept of risk acceptance, however, there is no systematic way of evaluation risks or to determine risk acceptability, this depend on individuals perception, institutions, and the community.
Before my summary, may I request your permission to appreciate you for taken time to give us an explicit lecture on the: Topic: Biorisk characterization and Evaluation. I was able to understand the following: 1. Biological risk assessment. 2. Introduction: A biological risk assessment is an analytical procedure designed to characterize biological risk in facility, laboratory or unit within it. Or other type of dealing with potential pathogens or toxins. Biorisk characterization and evaluation entail a systematic approach to identifying, assessing, and mitigating biological risks associated with pathogens or toxins in facilities, laboratories, or units. The primary objective is to ensure biosafety and biosecurity. 1. *Biological Risk Assessment*: A structured process to identify, evaluate, and characterize biological hazards, considering factors like pathogen virulence, transmission routes, and potential consequences. 2. *Risk Characterization*: Quantitative or qualitative analysis of the likelihood and potential impact of biological risks, informing decision-making and resource allocation. *Biological Risk Assessment Phases* 1. *Hazard Identification*: Recognize potential biological hazards (pathogens, toxins). 2. *Risk Assessment*: Evaluate likelihood and potential consequences. 3. *Risk Characterization*: Combine hazard and risk assessments to prioritize mitigation strategies. 4. *Risk Management*: Implement controls, monitor, and review. *Things to consider 1.

Enhanced biosafety and biosecurity 2. Reduced risk of accidents and exposures 3. Compliance with regulations and guidelines 4. Improved public health and environmental protection. Once again thank you very much Prof.
Thank you prof for this insightful lecture. In summary: Biorisk evaluation is a systematic process designed to categorize biological threats within laboratory settings or specific units. This comprehensive risk evaluation is bifurcated into biosafety risk evaluation and biosecurity assessment. Conducting a thorough biorisk evaluation is crucial, as it enables facilities or operations to ascertain the probability of adverse events, gauge the severity of potential repercussions, and inform strategic decisions for mitigation. The risk evaluation process comprises the following steps: 1. Identification of potential hazards and threats 2. In-depth characterization of hazards and threats, considering underlying causes and consequences 3. Relative risk assessment Two essential tools facilitating laboratory risk evaluation are Biosafety and Biosecurity Risk Assessment Matrix (Bio RAM). By streamlining risk characterization, Bio RAM enables a more efficient evaluation process. Risk evaluation serves as a critical intermediary step, bridging the gap between risk characterization and proactive mitigation measures. Several factors influence variations in risk tolerance, including: 1. Individual factors 2. Community factors 3. Institutional factors Thank you ma.
Thank you very much ma for this lecture. IN SUMMARY: I understood that Biorisk characterization and evaluation is the process of accessing the risk associated with biological agents such as genetically modified organisms (GMOs), etc. The goal of Biorisk characterization and evaluation is to: Evaluate the potential impact or consequences, To develop strategies for risk mitigation and management, To assess the likelihood of adverse effects, To identify potential hazards. Biorisk characterization and evaluation are critical in various areas including: 1. Agriculture: Assessing the risk of plant or animal diseases 2. Public health: Assessing the risk of infectious diseases or pandemics pandemics 3. Biosafety and Biosecurity: Developing strategies to prevent or migrate biological threats 4. Environmental risk assessing: Evaluating the potential impact of biological agents on ecosystem. Biorisk assessment is an analytical procedure designed to characterize security risk in a laboratory, it's factors include: 1. Security of agents 2. Accessibility 3. Access control 4. Location of lab
Thank you for this interesting lecture Ma it has help me understand that biorisk assessment is an analytical procedure designed to characterize biorisk in a facility, laboratory or unit within it, or other type of operation dealing with potential germs or toxins Biorisk assessment helps determine the relative level of risk its different activities poses in the lab and also helps guide risks mitigation decisions so that there are targeted to the most important risk. The aim of biorisk assessment is to determine the likelihood and the consequences of adverse event and support decision making regarding the acceptability of the risk.
In brief, Dr. lya Eze Bassey, your session on bio-risk characterization and evaluation left a strong impression. I appreciate your effective approach to simplifying risk identification and mitigation. The breakdown of key steps, such as outlining activities, recognizing threats, and balancing risk with research goals, is particularly valued. This knowledge is crucial for making informed decisions and prioritizing safety in our work. Thank you for sharing your expertise and making the session impactful After the lecture, learned that boorish characterization and evaluation is a systematic and scientific way to figure out the risks of biological agents. It helps us decide what actions to take to manage those risks.
Thank you Ma for this wonderful lesson I learnt about Risk Characterization which is the first step in risk assessment and is seen as the actual process of determining consequences of a particular risk within a risk assessment. Here, work activities are described, hazards & any threats are identified, also, risks are identified. In this first step, characterization of hazards & threats are based upon the likelihood & consequences. For hazards, likelihood of hazards to cause harm and the extent of the harm are considered. And for threats, likelihood of threats to successfully achieve their goal & the consequences of the goal are considered. I noted that a hazard or threat can't pose a risk without a specific situation & vice versa. Biological Risk Assessment which is an analytical procedure designed to characterize biological risks in a facility, laboratory or unit within it, or other type of operation dealing with potential pathogens or proteins. Biosafety Risk Assessment: is an analytical procedure designed to characterize safety risks in a laboratory. Biosecurity Risk Assessment: is an anayltical procedure designed to characterize security risks in a laboratory. The Need For Biorisk Assessment which is to determine the relative level of risk a laboratory, facility or operation's different activities pose, and helps guide risk mitigation decisions so dat these are targeted to the most important risks. Risk assessment being a process that characterizes a particular situation in order to determine the likelihood & consequences of a certain adverse event (risk characterization), and supports decision making regarding the acceptability of the risk( risk evaluation) The Objective of Risk Assessment which is to support the selection of appropriate lab biosafety & laboratory biosecurity risk mitigation measures to reduce likelihood and consequences of inner injury, falling ill sickness or break-ins (causing problems). Biorisk Factors That Affect Biorisk Assessment: -Method of waste disposal. -Duration of exposure. -Virulence in substances(highly infectious malignant or deadly substances). -Laboratory design. -Route of exposure. Biosecurity Factors That Affect Biorisk Assessment: -Motive of bad individuals. -Location of laboratory. -Security of the laboratory agents. Biosecurity & Biosafety Factors Affecting Biorisk Assessment: -Training/Staff competency. -Infrastructure/Equipment -Adherence to safety measures. When Characterizing risk: -Risk characterization process must be robust(i.e alot) -It must be comparable -It must be repeatable. I got to know about Biosafety & Biosecurity RAM [BioRAM], a computerized R.A tool developed to aid in laboratory risk assessment. Risk Evaluation which is the 2nd step in risk assessment is highly related to the concept of risk acceptance or acceptable risk. This is the process of determining subjectively whether a risk is high or low and whether it is acceptable (which leaves us to proceed with the work) or not to (leading us to implement risk mitigation measures). It is a crucial intermediary step between risk characterization & taking active steps towards mitigating risk. Factors That Drive Differences In Risk Acceptability Include: -Individual Factors which involve personal preferences, belief systems, reputation, funding. -Instutution Factors which include reputation, legal issues, funding, infrastructure, management, commitment, policies, rules & regulations. -Community factors which include community awareness, norms & values, belief systems, culture educational advancement, benefits, political & community interest, loss & damage. I noted that only an institution can determine whether a risk is very high, high, moderate, low and very low. I also learnt about the Risk Evaluation Graph which contains the risk tolerance curves plotted against likelihood & consequence. With risk averse (those who don't like risks) graph slightly different from the risk default graph, and the risk tolerant (those who accept risks) graph being much more different from the risk default graph and risk averse graph. Likelihood Adverse Institutions which are focused only on the potential (likelihood) of something bad happening but less concerned about specific level consequences. And Consequence Adverse Institutions which are focused about consequences, regardless of the potential for an occurrence.
Thanks for the wonderful lecture. Summary of what i learnt are as follow. Firstly i learnt biological risk risk assessment as analytical procedure design to charactise biological risk in an operation dealing with pathogens or toxins. A biosafety risk assessment is an analytical procedures in laboratory. Also biosecurity assessment which entains analytical procedures design to characterised security risk in lab. I learnt the level of repercussion associated with the risk as well as helping to guide mitigation decision. The steps involved in risk evaluation are. 1 identification of the hazards and treat. 2 characterisation of the harzard and treat. 3 Relative risk. Risk evaluation is crucial termediary step between risk characterisation and active steps taking towards risk mitigation. It weather the risk is low or high and if it acceptable or not. They are certain factors driving difference in risk acceptance they include 1 1 1individual factor. 2 Community factor. 3 institution factors. Thanks for the wonderful lecture.
This video thoroughly explains bio risk management, it's models, the need for bio risk assessment, risk evaluation and the benefits that comes with it. Firstly, bio risk assessment is an analytical procedure designed to characterize biological risks in a facility within it. This assessment covers both bio safety and bio security risk assessment. The former is an analytical procedure designed to characterize safety risks in a lab, while the latter is an analytical procedure designed to characterize security risks in a lab. >>The need of bio risk assessment allows a facility to determine the relative level of risks it's different activities pose, and helps guide risk mitigation decisions so that these are targeted to the most important risks. I have also come to understand that risk assessment can be said to be a process that characterizes a particular situation in order to determine the likelihood and consequences of a certain event. First step in a risk assessment is the ability to identify the hazards based upon the situation. The term hazard is used in the bio safety context, and threat is used in the bio security context. ~Risk evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risks. It determines whether a risk is high or low. Thank you ma 😊
Thank you ma for this wonderful section In summary of the the topic Biorisk characterization Biorisk characterization help us to evaluate route exposure,communicability,incubation time etc I also learned that BIORISK ASSESSMENTwhich is an analytical procedure designed to characterize biological risks in a laboratory with potential pathogens,to determine the likelihood and consequences Factors that drive different in capabilities between individuals and community are 1community Awareness,norms and values 2individuals 3.institution BIO RAM Biosecurityand biosafety is a computerised risk assessment tool developed for laboratory safety and bio security risk.
I want to appreciate your vulnerable time Ma for this great lecture. In summary of what I learnt about Biorisk Characterization Biorisk assessment is an analytical procedure designed to classify biological risk in a facility, laboratory or unit within it . Biorisk assessments is divided into two Bio safety risk management Bio security risk management I also learnt that Biological risk assessment is a very important because it allows a laboratory or operation to determine the relative level of risk in it’s different activities pose , it also helps to guide risk mitigation decisions. WHAT IS RISK : I also learnt that risk is the likelihood of an undesirable event happening that involves a specific hazard or threat and has consequences. I also learnt that the first step in a risk assessment is the identification of HAZARD AND THREAT. Hazard is something with the potential to cause harm, it’s used in the Biosafety context while Threat is someone with intent to cause harm and it’s used in the Biosecurity context. STEPS INVOLVED IN RISK EVALUATION 1:Identification of the hazard and threat 2:Relative risk Ma I also learnt that one of the available tools to aid in the laboratory risk assessment is the BIOSAFETY AND BIOSECURITY RAM (BIO RAM ) . BioRam is a computerized risk assessment tool developed by sandia natural laboratory, it achieves this by simplifying risk characterization. I also learnt about Risk Evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigation risk. Certain factors driving difference in risk are 1:community factors 2:individual factors and 3:institution factors. Thank you ma ❤.
Thank you so much Dr Iya Eze. I understood the breakdown of bio risk characterization and evaluation, also identifying biological agents, evaluating potential impacts and assessing exposure were well explained. The practical insights on consequence analysis and likelihood estimation for prioritizing risks. You emphasized on continous monitoring and adpating stategies highlighted the importance of always staying proactive. Due to your always detailed explanation i was able to understand that Bio Risk. assessment is a careful procedure made to characterise biological risks in the laboratory. There is no systematic way of evaluating risk or to determine risk acceptability. It's all about the perception of the institution or individual and even communities.
I learnt that Biorisk characterisation and Evaluation is the process of assessing the potential risk associated with biological agents such as pathogen,toxins and genetically modified organisms.This involves identifying hazard threat and vulnerabilities to determine the likelihood and potential impact of adverse events. Hazard refers to the intention of biological agents that can cause germs, while threats refer to the intention of using these agents for malicious purposes.BIO RAM (biological risk assessment and management) is a framework used to guide the very process considering factors such as exposure routes mitigation strategies What factors might drive different in risk capabilities between individuals, institution and communities; Institution---funding, reputation,belief system Institution----legal issues,polices, rules and regulations Community factor---community awareness,norms, and values and many more..thank you Ma
I recommend every one hungry for knowledge to watch these videos from Dr. Iya Eze Bassey. A biological risk assessment is all about procedures that characterize biological risk in the laboratory, facilities or operations dealing with potential pathogens. Biosecurity risk assessment characterize security risk in a laboratory. Biosafety and Biosecurity RAM is one of the tools that aid risk assessment in the laboratory. Thank you so much ma'am.
Thank you ma for yet another educative and insightful lecture. In summary biorisk assessment is an analytical procedure designed to characterise biological risk in a laboratory, facility, unit or any other type of operation dealing with pathogens or toxins. Risk management is designed to characterise safety risk in laboratory. The main goal of risk assessment is to support the selection of appropriate laboratory bio safety and bio security risk mitigation measures so as to reduce any consequences or likelihood ( weather hazards or threats). Biorisk characterization and evaluation goal is to ensure the safe handling, storage and use of biological materials and to prevent or minimize the risk of adverse effects on human health, the environment and economy.
Thank you ma for the superb lecture Summary of what i learned Biohazard Risk Assessment is a systematic process to identify, evaluate, and control biological risks in a laboratory setting. It involves determining the likelihood and potential consequences of a specific biohazard, such as a pathogen or toxin. By understanding the risks, laboratories can implement appropriate safety measures to protect personnel,the environment, and the public.
I gained a better understanding of the dangers of working in a laboratory that handles biological materials thanks to this video, which also explained what risk and biorisk are, what they mean, and what precautions to take. It allows me to comprehend and provides solutions to all the important questions of biosafety and biosecurity, which are all about management. I gained knowledge about biorisk management systems and the components of an effective management system.
Good day ma and Thank yoy for this Wonderful Insights on Bio risk Characteristics and Evaluation. i learnt a Lot o things which Includes that Biological Risks assessment is an Analytical procedure designed to Characterised Biological risks in a laboratory or other Type of Operation dealing with Potential toxins. Biosafety risk assessment has to do with safety risks in a Laboratory while Biosecurity risks assessment has to do with the Security risks in a Laboratory. Risk assessment helps reduces the Likelihood and Consequences of Injury, Sickness etc in the Lab. The first step in risks assessment is being able to identify the Hazards and Threat, the Hazards has to do with something with the Potential to cause harm while the threat has to do with and Individual with the Motive to cause Harm.
I must confess that this is one of the best lectures I have had in my life, God bless u for the wonderful section. Ma, at the end of the video I was able to pick out the following points: Firstly, I learned that biorisk characterization and evaluation are the basic tools for risk assessment, and risk characterization has to do with the process of determining the likelihood and consequences of a particular risk happening within a risk assessment, whereas risk evaluation has to do with a crucial intermediary step between characterization and taking action towards mitigation decisions. Secondly, I learned that before a risk can be characterized, it should be first of all assessed by identifying the hazards or threat that is involved in that particular risk, and this characterization could be a biosafety characterization in which the hazardnis a biological agents or a biosecurity characterization in which the hazard could be an adversary aiming to acquire the biological material and use it to cause harm. Thirdly, I also came to the realization that for the biorisk assessment to be achieved, they are certain tools that need to be put in place. E.g of such tools are the biosafety and biosecurity RRM ( BioRAM) . Which is a computerized assessment tool that was developed by the Sandi national laboratories in partnership with the international community to facilitate laboratory biosafety and biosecurity assessment. Finally, with the knowledge I have gotten from the lecture, I can now boldly say without any doubt, that risk assessment helps us to characterize our risk, evaluate it, and decide whether or not the risk is acceptable. God bless you ma for the video, we are so much grateful and we pray u do more videos for us ... 🙏🥰💕🙏
'' Biorisk characterization and evaluation " . I learnt that biorisk characterization is the process of determing the likelihood and consequences of a particular,well defined risk with in a risk assessment. I also know the difference between hazard and threat is that hazard is something that has the potential to cause harm where as threat is someone that has an intent of causing harm . I learnt that there is no systematic way of evaluating risk because it usually depends on individual, institution and community difference which plays a crucial role in determining how high or low a risk is and it acceptability . and also about the bioram application which is a computerized risk assessment tool. Lastly,I learnt about the difference between not"Risk Adverse " & "Risk Tolerance," likelihood adverse "& consequence Adverse" and their graphical representation. Thank you so much prof . IYA EZE for the organization of the video lesson. God bless you MA'AM.
In summary, regarding Biorisk characterization and evaluation it involves assessing the potential risks associated with biological agents or materials. This process includes identifying evaluating the likelihood of exposure, and determining the consequences of such exposure. Key points in biorisk characterization include understanding the nature of the biological agent, its pathogenicity, and the routes of transmission. Evaluation involves assessing the impact on human health, the environment, and biosecurity measures. Notable findings may include the identification of high-risk areas, vulnerable populations, and potential mitigation strategies to reduce biorisk... Overall, biorisk characterization and evaluation are essential components of biosafety and biosecurity measures to prevent the spread of infectious diseases and protect public health. Thank you ma for all your effort to ensure that we come out with excellent grades.
Thank you madam for a satisfying lecture I learnt that Biorisk characterization is the determing the process of livelihood and consequences of a well defined risk within a risk assessment Risk assessment is an analytic procedure designed to characterise biological risk facility or other type of operation dealing with potential toxins
Thank you ma for the lecture I learnt that: A biological risk assessment is a procedure that characterizes bio risk un a facility, laboratory ir unit within it. Biosafety risk assessment characterizes safety risk in the laboratory. Bio security assessment characterizes security risk in the lab. Risk assessment is a process that characterizes a particular situation to determine the likelihood or consequences of certain adverse effects. BIO RAM( Bio security and Bio safety) This is a tool developed for lab safety and biosecurity risk assessment.
Thank you very much ma for this wonderful lecture It has been said that A biological risk assesment is an analytical procedure designed to characterize biological risk in the laboratory facility or unit dealing with potential pathogens or toxins In other words it is designed to characterize the security risk in a laboratory Why do we need bio risk assesment .. It allows a facility or laboratory to determine the relative level of risk .. It helps guide risk mitigation RISK:also said to be the likelihood of undesirable events that occur resulting to death, injury, hazard and damage. Bio risk characterization and evaluation also involves assesing the potential risk associated with biological agents or materials. This process involved identifying hazards, evaluating the likelihood of exposure and determining the consequences of such exposure They key points to bio risk include understanding the nature of biological agents, its pathogenity and the routes or transmission. Evaluation involves accesing the impact on human health, the environment and bio security measures. Note:the term HAZARD is used in biosafety and THREAT is used in biosecurity.

Thank you so much ma for this knowledge
Thank you so much ma for this online lecture. I was able to understand most things about bio safety risk assessment as an analytical procedure design to characterize safety in the laboratory.. I also understood the reason why we should carry out biological risk assessment, the reason is because it allows a facility, laboratory or other operations to determine the relative level of the risk, it's different activities pose, and help good risk mitigation decisions so that the are targeted to the most important risk. I was able to know the factor that affects biosafety which includes; 1) method of waste disposal 2) virulence 3) duration of exposure. IN RISK CHARACTERIZATION The first and second steps in the identification of hazard and threat based upon the situation; 1) A hazard is something with the potential to cause harm. 2) A threat is someone with intent to cause harm. This means that "hazard" is used in the biosafety context while "threat" is used in the biosecurity. The next step in the risk assessment is the characterisations of the hazard and threat based on the likelihood and consequences. 1) For hazard, consider the likelihood of the hazard to cause harm and the extent of the harm. 2) For the threat, consider the likelihood of the threat to successfully achieve their goals and the consequences of that goal. Thank you once again ma for this impactful lecture. May God grant you wisdom to impact on us..
Thank you very much Dr. Iya Eze Bassey for this great lecture. IN SUMMARY: Biorisk assessment is an analytical procedure designed to classify biological risk in the laboratory or units within it.

Thank you very much ma'am for this lecture. BIORISK CHARACTERIZATION This helps to evaluate route exposure . Characterization and biorisk evaluation modifies pathogens, toxins and genetic materials I have also learnt that risk assessment Is characterized by Biosafety risk assessment Biosecurity risk assessment..... In conclusion, there's no systematic way if determining risk acceptability, This will depend on the perception of individuals
Thanks for the informative lecture. I learnt that Bio risk characterization is important in evaluating the communicability of biological hazards and helps in accessing, tracing, identifying and prioritizing bio risks. Also, bio risk evaluation and characterization helps in modifying toxins and pathogens, all aimed at safety in the Laboratory. And the process of characterizing these risks is called risk assessment which also has strategies and approaches to it. I also understood that BioRAM (Biosafety and Biosecurity RAM) is a computerized risk assessment tool which was developed by Sandia National Laboratory in partnership with International Community. Bio RAM helps in determining relative risk levels. In conclusion, accepting that there are such dangerous risk in the laboratory is the first step towards ensuring safety in the laboratory
Thank you very much ma for this lecture I understood that a biological risk assessment is an analytical procedure designed to characterize biological risks in a facility, laboratory or unit within it, or other type of operation dealing with potential pathogens or toxins A biosafety risk assessment is an analytical procedure designed to characterize security risks in a laboratory A biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory Reasons why we need a biological risk assessment: A biological risk assessment allows a facility, laboratory, or other operation to determine the relative level of risk it’s different activities pose I have learned and understand that risk characterization is the process of determining the likelihood and consequences of a particular risk with a risk assessment. While risk evaluation I'd determining whether a risk is high or low, whether it is acceptable or not which can lead to implementation of risk mitigation measures. I learned about a BioRAM which is a computerized risk assessment tool used to facilitate biosafety/biosecurity risk assessment by simplifying risk risk characterization.
Thank you very much for an amazing lecture Here's brief summary of what ive learnt... I learned thst Biological risk assessment is an analytical procedure designed to characterize biological risks in a facility, laboratory or unit within it or other types of operation dealing with potential pathogens or toxins. Biological risk assessment is categorized info Biosafety risk assessment and Biosecurity risk assessment. Biological materials are one of the highest levels of risks. We need biological risk assessment cause it allows a facility, laboratory or other operation to determine the relative level of risks, it helps guide risk mitigation decisions so that these are targeted to the most important risks. In summary,the risk tolerance curves shows different levels of risks from very low to very high. Thank you ma once again.
Thank you Ma for the enlightening lecture. I learnt about the meaning of Biological risk Assessment, The need for Bio-risk assessment, Factors to consider during Bio-safety and Bio-security Risk Assessment, The Steps involved in Risk Assessment, The BioRAM Tool and lastly Risk Evaluation and it associated terms. Biological Risk Assessment: is a procedure carried out to characterize biological risks in a laboratory. It cuts across that of biosafety and biosecurity risks. Biosafety risk assessment is used to characterize safety risks while that of biosecurity is used to characterize security risks. The need for a biological risk assessment is to allow a laboratory or facility know the risks associated with different activities (risk characterization) and helps in guiding mitigation decisions (risk evaluation). Factors to consider during biosafety risk assessment are: 1. Method of waste disposal 2. Duration of exposure to the biological agents 3. Route of exposure 4. Laboratory Design Factors to consider during biosecurity risk assessment are: 1. Location of the Laboratory. 2. Access Control 3. Accessibility There are also factors that apply to both biosafety and biosecurity, they include: Infrastructure/Equipment, Training/Staff competency and adherence to safety measures. Biorisk Assessment involves two steps: 1. Bio-risk Characterization: This is the identification of hazards and threats based upon the situation. Hazard is used in the biosafety context, while threat is used in that of biosecurity. For a risk characterization to be termed as robust, it must have these qualities: i. Comparability: the ability to trust the accuracy of the differences between assessments. ii. Repeatability: rhe ability to conduct the same process on the same way for same hazard or threat. In order to aid in risk assessment, the BioRAM which is a computerized tool helps to facilitate assessments by simplifying risk characterization. 2. Risk Evaluation: This is an intermediary step between risk characterization and taking active steps in mitigating the risk. Noted is the fact that determining or evaluating risk do not involve a systematic way but depend on the perception of individuals, institutions and community. To also communicate risk evaluation, the " risk tolerance curves" is used to show different levels of risks on a likelihood consequences graph of risk. Terms associated with risk evaluation are: Risk Adverse: When the graph of an institution shows more space for high risk, i.e they do not want any risk. Risk Tolerant: When the graph of an institution shows more space for low risk, i.e they are ready to take chances. Likelihood Adverse: When an institution focus more on the likelihood of a risk than the consequences. Consequences Adverse: When an institution is more concerned about the consequences than the potential of an occurence. Once again, Thank you Ma.
Thank u so much ma ❤ for this wonderful lecture. Bio risk characterization and evaluation talks about the biological risk assessment, which is an analytical procedure designed to characterize biological risk in a facility, laboratory, or unit within it, or other type of operation dealing with potential pathogens or toxins. Which has to do with: Biosafety risk assessment Biosecurity risk assessment Biosafety risk assessment is the analytical procedure designed to characterize safety risks in a laboratory, while Biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory. Why we need a biological risk assessment: It is because it allows a facility, laboratory, or other operation to determine the relative level of risk its different activities pose and helps guide risk mitigation decisions so that these are targeted to the most important risks. And evaluating the kind of risk we can be faced with using the likelihood and consequences and how fast we will act and the kind of protective equipment to be used. The objective: Biosafety and laboratory biosafety risk mitigation measures to reduce likelihood and consequences. And also I learnt about hazards: Hazard is something with the potential to cause harm, while threat is someone with an intent to cause harm. And how risk are characterized into rubust, comparative and repeatability using the BioRam tool the evaluation of risk in their different understanding, thanks ma.
Thankyou ma for the lecture I learnt that, Bio risk management is basically a process systematically put in place before effective control safety and biorisk, it’s the likelihood of undesirable events that involves hazard, threat and consequences. _The use of personal protective equipment can lower the likelihood of exposure. _The use of physical barriers can lower the likelihood of theft. The process of bio risk characterization must be Robust, Comparable and Reputable. Components of bio risk management -Assessment -Mitigation -performance.
Thank you so much ma for the wonderful lecture. I learnt that biorisk assessment is an analytical procedure made or designed to characterise biological risks in a faculty, unit ir laboratory within it. Risk assessment is a procedure or process that characterizes a particular situation in order to determine the likelihood and consequences of a certain adverse event and support decision making regarding the acceptability of the risk. Risk characterization is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment. Biosafety Risk Assessment is an analytical procedure designed to characterize safety risks in a laboratory. Biosecurity risk is assessment is an analytical procedure designed to characterize security risks in a laboratory. I also learnt that hazard are things with the potential to cause harm while threats is someone with the intention to cause harm.
The breakdown of bio risk characterization and evaluation was very helpful. Risk characterization is the actual process of determining the consequences and likelihood of a particular risk occuring.. Two steps of risk characterization: 1.) Identification of hazard 2.) characterization of the hazard Risk evaluation is the intermediate step between risk characterization and mitigation. A relative risk is the value of one particular risk in terms of likelihood in the context of another risk. In summary the Amp model is vital in the execution of bio risk management.
Thank you very much, Ma. Your lecture was incredibly informative. I learned that: A risk assessment is a process that characterizes a particular situation in order to determine the likelihood and consequences of a certain adverse event (Risk Characterization) and supports decision making regarding the acceptability of the risk (Risk Evaluation). A biosafety risk assessment is an analytical procedure designed to characterize safety risks in a laboratory. While a biosecurity risk assessment is a procedure that is designed to characterize security risks in a laboratory. Risk is a function of both the likelihood of something happening and consequences of that occurrence. Some of the factors that could affect biorisk assessment include: * Training/Staff competency * Infrastructure/Equipment * Adherence to supply measures Steps in risk assessment are: * Identification of hazards and threats based on the situation. * Characterization of the hazards and threats based upon the likelihood and consequences. * The concept of relative risk. Understanding the relative risk associated with different situations or by implementing different risk mitigation strategies is important for the overall process of risk characterization. Risk Evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risk. It is highly related to the concept of risk acceptance. Individual, Institution, and community factors might drive differences in risk acceptability.
Thank you ma for this lesson Below are the few things I've learnt from this lesson ma Biological risk management is an analytical procedure designed to characterise biological risks in a facility, laboratory or unit with it or other types of operations dealing with potential pathogens or toxins. Biological risk management are two types; the BIOSAFETY RISK ASSESSMENT; which is an analytical procedure designed to characterise safety risk in a laboratory. And BIOSECURITY RISK ASSESSMENT; which is an analytical procedure designed to characterise security risks in a laboratory. Why we need biorisk assessment is because it allows a facility, laboratory or other operation to determine the relative level of risk,it different activities pose and helps guide risk mitigation decisions so that these are targeted to the most important risk. A risk assessment assigns values for likelihood and consequences,which allows to represent the risk of a particular adverse event on a graph. The objective of risk assessment is to support the selection of appropriate laboratory Biosafety and laboratory Biosafety risk mitigation measures to reduce likelihood and consequences of injury, sickness or breaking into the lab to take those highly risk pathogens. The biosafety factors includes; method of waste disposal, duration of exposure,lab design, route of exposure, virulence. Biosecurity factors are; motive of the person, security of the agent, accessibility, location of lab,access control and opportunity. Also,Risk characterisation is the actual process of determining the likelihood and consequences of a particular risk assessment. We can only determine the likelihood of consequences of a very well defined risk. Also, characterising the material allows one to determine important parameters for likelihood and consequences such as route of exposure, infectious dose, incubation time, mortality,communicability and others. For biosecurity risks,the threat is an adversary, aiming to acquire the biological materials (hazard) and use it to cause harm. A hazard or threat cannot itself pose a risk without a specific situation. A situation also does not represent a risk without a hazard or threat. Both a changing hazard or threat and a changing situation will independently alter the scenerio being assessed and thus change the risk. Relative risk is the value of one particular risk (in terms of likelihood a d consequences)in the context of another risk. It is important that risk characterisation process should be as robust as possible. Comparability is the ability to trust the accuracy of differences between assessments,due to similarities in their bases, assumption, procedures and protocols. Repeatability is the ability to conduct the same process in the same way for the same hazard or threat and situation over a period if time or for different hazards,threats and situations at the same time. Robust risk characterisation process will generate similar results when assessing similar hazards or threats in similar situations,no matter who is following the methodology. A robust risk characterisation makes a risk assessment robust. BioRAM is the available tool to aid if laboratory risk assessment is biosafety and security RAM. Risk evaluation is a crucial intermediary step between risk characterisation and taking active steps towards mitigating risk. The factors that might drive differences in risk acceptability between individuals, institutions and communities are; Individual factor; which are personal preference,beliefs system, reputation and funding Institutional factors; which are reputation,legal issues, funding, infrastructure, management, commitment, policies,rules and regulations. Community factors; which includes community awareness,Norms and values and belief systems, culture, educational advancement, benefits, political and community interest. And finally, consequence averse is when an institution os only worried about the consequences regardless of the potential for an occurrence
Biorisk Characterization helps us to evaluate infectious diseases, incubation time and route exposure. I also understand, how to identify and characterised those risks that are rising in the laboratory. I also understand that Biorisks evaluation and characterization is the processing of assessing the potential risk associated with biological agent and it also modified pathogen, genetic material and toxins and expose biological agent that cause gems. Bio Ram: It is a computerized risks assessment tool developed for laboratory safety and bio security risks assessment. Thank you ma for this wonderful lecture
Thank you very much for your insightful and informative lecture on BIORISK CHARACTERIZATION AND EVALUATION. To summarize, a biological risk assessment is a systematic process that aims to identify and evaluate risks associated with potential pathogens or toxins within a facility or laboratory. Conversely, biosafety risk assessment focuses on safety risks within a laboratory setting, while biosecurity risk assessment targets security risks. Understanding the importance of conducting a biological risk assessment is crucial. It allows facilities and laboratories to assess the level of risk posed by their activities and make informed decisions to effectively mitigate these risks. Risk, in this context, refers to the likelihood of an undesirable event occurring, which involves specific hazards and potential consequences. Risk assessment involves analyzing a situation to determine the probability and potential impact of adverse events. Assigning values for likelihood and consequences enables us to visualize the risk on a graph and prioritize risk management strategies accordingly. Factors influencing biosafety include methods of waste disposal, exposure duration, pathogen virulence, laboratory design, and routes of exposure. Similarly, biosecurity is influenced by motives, laboratory location, agent security, access control, and opportunities for breaches. Risk characterization involves assessing the likelihood and consequences of identified risks within a risk assessment framework. Comparability ensures accuracy in evaluating differences among various risk assessments, while repeatability focuses on the consistency and reliability of conducting risk assessments over time and across different hazards and scenarios. Lastly, BioRAM, developed by Sandia National Laboratories in collaboration with the international community, is a computerized tool designed to facilitate laboratory risk assessments.
Thank you ma'am, In this lecture I learnt that bio risk mitigation are actions and control measures that are put in place to reduce the risk associated with biological toxins and agents . There are five basic mitigation control methods which are: 1. Administrative control : These are policies that result in providing proper guidance for safety 2. Engineering control: it has to do with the physical change in the environment that reduces or prevent hazard this method is most effective but costly measure it requires regular maintenance 3. Elimination and substitution : elimination involves the removal of hazards from biological agents completely while substitution involves replacing a hazardous substance or process with a safer alternative 4. Practices and procedures 5. Personal protective measures: This simply involves the provision of individual protective equipment such as gloves, respirators etc. This is the least preferred method because it depends only on the individual usage of the equipment however the most level method will depend on the type of risk
Bio risk characterization plays a crucial role in assessing various aspects of exposure to biological agents, including routes of exposure, communicability, incubation periods, and the potential for infectious diseases. Through this process, I have gained insights into how to identify and evaluate emerging risks within laboratory settings. Additionally, I learned that bio risk evaluation and characterization involve the analysis of modified pathogens, toxins, and genetic materials, as well as identifying biological agents that may pose risks, such as pathogens that can spread germs. Several factors contribute to the differing capabilities of individuals and communities in managing these risks: 1. Community Awareness:The level of knowledge, norms, and values within a community significantly influences its ability to respond to bio risks. 2. Individual Beliefs: Personal reputation and belief systems can affect how individuals perceive and react to risk. 3. Institutional Frameworks: Institutional rules, legal regulations, and policies play a vital role in establishing safety protocols. Moreover, there are computerized risk assessment tools specifically designed for evaluating laboratory safety and biosecurity, enhancing our ability to identify and mitigate potential threats effectively.
Thank you ma for yet another wonderful lecture on Biorisk Characterization and evaluation . At the end of this lecture I was able to understand the process of identifying and describing the biological agent, its properties, and its potential risks. What is Bio risk assessment? Bio risk assessment is the process of assessing the likelihood and potential impact of a biological agent causing harm. Biosafety risk assessment: Bio safety risk assessment characterizes safety risks in the laboratory. It also determines the level of risks that can be caused by different activities. Biosecurity risk assessment: is an analytical procedure that is designed to characterize security risk in a laboratory. Why do we need it? - it allows the facility,laboratory or other operations to determine the relative level of risk and helps guide risk mitigation. What is Bio mitigation: They are those actions or control measures that are put into place to reduce or eliminate the risks associated with biological agents and toxins. Biorisk characterization: this determines the likelihood and consequences of a particular risk. Biorisk characterization helps us to evaluate route, exposure, incubation time and infection disease. Bio risk evaluation modifies pathogens,toxins and genetics materials. Steps in Biorisk Evaluation_: 1. Hazard Identification_: Identify the biological agent and its potential hazards. 2. Risk Assessment: Assess the likelihood and potential impact of the biological agent causing harm. 3. Risk Characterization_: Describe the risk in terms of its likelihood and potential impact. 4. Risk Mitigation_: Identify and implement controls to mitigate the risk. Factors to Consider in Biorisk Evaluation 1. Agent Characteristics_: The biological agent's properties, such as its: - Virulence - Transmissibility - Stability - Reactivity 2. _Exposure Pathways_: The ways in which individuals may be exposed to the biological agent, including: - Inhalation - Ingestion - Skin contact - Mucous membrane contact 3. _Vulnerable Populations_: Individuals who may be more susceptible to the biological agent's effects, including: - Immunocompromised individuals - Pregnant women - Children - Elderly individuals 4. _Environmental Factors_: Environmental conditions that may affect the biological agent's survival and transmission, including: - Temperature - Humidity - Lighting - Ventilation Risk Assessment Methodologies 1. _Qualitative Risk Assessment_: A subjective approach that uses expert judgment to assess the risk. 2. _Quantitative Risk Assessment_: An objective approach that uses numerical data to assess the risk. 3. _Semi-Quantitative Risk Assessment_: A combination of qualitative and quantitative approaches. Benefits of Biorisk Characterization and Evaluation 1. _Informed Decision-Making_: Biorisk characterization and evaluation provide valuable information for decision-making. 2. _Risk Mitigation_: Identifying and evaluating bio risks enables the implementation of effective risk mitigation measures. 3. _Compliance with Regulations_: Biorisk characterization and evaluation help ensure compliance with relevant regulations and guidelines. Thank you ma.
Thank you ma.. in summary i learnt that biorisk assessment is an analytical procedure designed to characterized safety risk in a laboratory while risk assessment is a process that characterize a particular situation in order to determine the likelihood and consequences of a certain adverse event .Risk evaluation is also taking steps towards mitigating risk..
BIO RISK CHARACTERIZATION Thank you so much ma I really understand a lot I understood that bio risk characterization and evolution involves the process of biosafety assessment, which is also the measure taken to identify an characterize those risks that are rising in the laboratory, which is as a result of working with biochemical specimens and also from handling laboratory equipments. Physical risks involved in the laboratory that deals with biochemical samples as a whole. It also identifies hazards that threats base on the specific situation and one of the important tools that facilitate the assessment of laboratory risks is the BIO RAM.
Thank you ma for this teaching. In summary, I've learnt that Bio risk allows a medical laboratory scientist to determine the relative level of risk and different activities pose and helps guide risk mitigation decisions and also got to know the difference between biosafety and biosecurity factors and I learnt that characterization and evaluation helps to identify and access specific biorisk which will further aid to prefer the right mitigation measures. Lastly I learnt the different risk and hazards associated experiments that take place in the laboratory and one of the ways of avoiding this risks
Thank you dr Iya Eze Bassey for this simplified lecture. Through this lecture i have learnt that bio risk characterization is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment and the first step in risk assessment is the identification of ; 1. Hazards 2. Threats based upon the situation Risk evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risk. It is hugely related to the concept of risk acceptance. Also through this lecture I got to understand that in characterizing risk under biosafety you have to adhere to this ; - The use of PPE can lower the likelihood of exposure - Vaccines can lower the consequences of exposure While under biosafety - The use of physical barriers aids in lowering the likelihood of theft. - The availability of therapeutics can lower the consequences of malicious release * It is also important to note that precise location of the risk tolerance curve on the graph is fact arbitrary and it's the essence of risk evaluation.
Thank you for the wonderful lecture Here is the summary; Biorisk characterization is the actual process of determining the likelihood and consequences of a particular adverse event.... *Steps for biorisk characterization* Step1: identification ofa hazard and threat based upon the situation Step2: characterization of hazard and threat based upon the likelihood and consequences. Step3:decide whether its acceptable or not.if yes;proceed with your work and monitor If no;close down the project....prepare a risk control action plan, implement and then review the plan For hazard,consider the likelihood of the hazard to cause harm and the extent of the harm (biosafety risk) For threat consider the likelihood of the threat to successfully achieve their goal and the consequences of the goal. *Biosafety risk characterization* The hazard is the biological material worked with in the lab. Characterization of material allows one to determine important parameters for likelihood and consequences such as route of exposure, infectious dose, incubation time, mobility, mortality, communicability and others. *Biosecurity risk characterization* For biosecurity risk,the threat is adversary aiming to acquire the biological materials and use it to cause harm.characterising potential adversaries allows one to determine important parameters for likelihood and consequences such as means,motives and opportunity. A hazard or threat cannot itself pose a risk without a specific situation and neither does a situation.both a changing hazard or threat and changing situation can alter the scenario being asssessed and this changes the risk. The hazard or threat can affect both the likelihood and consequences of a risk,the situation will only affect the likelihood and the consequences will remain the same because the agent will not change..... *Relative risk* is the value of one particular risk(in terms of likelihood and consequences)in the context of another risk. It is important that your risk characterisation is as robust as possible It will generate similar results when assessing similar hazards or threats in similar situations no matter who is following the methodology where the characterization is being conducted and when its occuring. BIORAM;is a computerised risk assessment tool developed by Sandia laboratories in partnership with international communities to facilitate laboratory biosafety and security risk assessment by simplifying risk characterisation.its uses only one of several possible risk assessment methodologies.it helps to determine the relative risk levels in a comparable and repeatable way. * RISK EVALUATION* Are crucial intermediary steps between risk characterisation and taking active steps towards mitigation risk.it helps to determine whether a risk is high or low and whether it is acceptable to proceed with or not (leading to implementation of risk mitigation) Different institutions have different opinions for what is high or low or even what shapes of the curves are. Risk evaluation drives investment decisions in an institution particularly risk averse,it will spend more time in reducing the risk. It proceeds with procedures even if others think it dangerous...(I.e likelihood averse) Consequences averse: an institution is worried about the consequences regardless of the potential for an occurrence. Once again..thank you ma for the lecture
Thank you ma for this well explained lecture. I really got value. I learnt about Risk Assessment as it tends to affect biosafety *Hazards-* biological materials that causes harm and biosecurity *Threat-* someone with an intention to cause harm. Biological risk assessment has to do with the process of evaluating the potential risk associated with biological agents. It entails hazard identification, risk assessment, risk characterization and risk management. It comprises Biosafety risk assessment and Biosecurity risk assessment. I discovered the factors that affect Biorisk assessment and they are: Waste disposal methods, virulence, route of exposure, motive, accessibility, access control etc. Furthermore, I realised that Biorisk characterization is the process of determining the likelihood and consequences of a particular, well defined risk within a risk assessment. This process must be robust, comparable and repeatable. Moreover, there are some steps to take in the Risk assessment; • Identify the hazards and threats based on the situation. • Understand the concept of Relative risk. • Characterize the hazards and threats bases on likelihood and consequences. I got to understand that *Hazard* is something (biological material) with the potential to cause harm while *Threat* is someone with the intent to cause harm. This brings about the Biorisk blackmailing. Lastly, the 'Risk likelihood Averse' and 'Risk consequence Averse' graphs disclosed the different risk tolerance levels.
Thank you ma for the wonderful lecture I learnt that; 1. Bio risk management is basically a process 2. The use of personal protective equipment can lower the likelihood of exposure. 3. Bio risk management is basically the process systematically put in place before effective control safety and bio risk 4. Bio risk is the likelihood of undesirable events that involves hazards, threats, and consequences 5. The use of physical barriers can lower the likelihood of theft. The process of Bio risk characterization must be ROBUST, COMPARABLE, AND REPUTABLE.
From the wonderful lecture i waa able to deduce that Biorisk evaluation and characterizations is an analytical procedure designed to characterise biological risks in a facility, laboratory or unit within it or other type of operation dealing with potential pathogens or toxins A biosafety risk assessment is an analytical procedure designed to characterise safety risks in laboratory We need biological risk assessment because it allows facilities,labs or other operations to determine the relative levels of risk activities pose and help guide risk mitigation decisions
Thank you ma for the well explianed lecture I learnt that biological risk assessment is an analytical procedure designed to charactrize biological risk in a facility,laboratory or unit within it,or other type of operation dealings with potential pathogens or toxins It consists of (1) Biosafety risk assessment - is an analytical procedure designed to characterize security risk in a laboratory. (2) Biosecurity risk assessment-allows a facility, laboratory or other operation to determine the relative level of risk its different activities pose and helps guide risk mitigation decisions so that these are targeted to the most important risk Risk is the likelihood of an undersirable event happening, that involves a specific harzard or threat and has consequences. Bio Ram- Biosecurity and Biosafety is computerized risk management Tool developed for laboratory safety and bio risk assessment
Thank you so much ma for this wonderful lesson on "Bio Risk Characterization and Evaluation", I understand a systematic process to: 1. *Identify*: Recognize potential biological hazards (e.g., pathogens, genetically modified organisms, biological waste) 2. *Characterize*: Determine the intrinsic properties and characteristics of the biological hazard (e.g., virulence, transmissibility, stability) 3. *Assess*: Evaluate the likelihood and potential impact of exposure to the biological hazard 4. *Evaluate*: Compare the bio risk to established standards, guidelines, and criteria to determine the level of risk This process involves: 1. *Hazard identification*: Identify potential biological hazards 2. *Risk assessment*: Evaluate the likelihood and potential impact of exposure 3. *Risk characterization*: Determine the severity and probability of adverse effects 4. *Risk evaluation*: Compare risks to established standards and criteria The goals of bio risk characterization and evaluation are to: 1. *Determine the level of risk*: Assess the likelihood and potential impact of exposure 2. *Inform risk management decisions*: Provide data-driven insights to guide bio risk mitigation strategies 3. *Prioritize resources*: Allocate resources effectively to manage bio risks 4. *Ensure compliance*: Meet regulatory requirements and guidelines By characterizing and evaluating bio risks, organizations can develop effective risk management strategies to mitigate potential biological hazards and ensure a safe working environment.
Thank you Ma for the wonderful teaching. I have learnt so much for this episode Like ...... Bio-risk characterization and evaluation are essential steps in bio-risk management! Bio-risk characterization involves: 1. *Identifying* potential biological hazards (e.g., infectious agents, toxins, genetically modified organisms). 2. *Assessing* the likelihood and potential impact of an adverse event (e.g., exposure, infection, environmental release). 3. *Describing* the characteristics of the biological material (e.g., virulence, transmissibility, stability). Bio-risk evaluation involves: 1. *Analyzing* the information gathered during characterization. 2. *Determining* the level of risk associated with the biological material (e.g., low, moderate, high). 3. *Categorizing* the risk based on established guidelines (e.g., WHO, CDC, NIH). The goals of bio-risk characterization and evaluation are to: 1. *Understand* the potential risks associated with biological materials. 2. *Inform* decisions about handling, storage, and use. 3. *Develop* effective risk mitigation strategies. By conducting thorough bio-risk characterization and evaluation, laboratories, organizations, and individuals can minimize the risks associated with biological materials and ensure a safe working environment
Thank you very much ma for this wonderdul lecture I have learned alot .. Firstly what is Risk Risk is the likelihood of all undesireable event happening that involves a specific hazard or threat and has consequences.. I also learnt that biorisk assesment is an analytical procedure designed to classify biological riak ina facility ,laboratory,or a unit within it.. Biorisk assesment is divided into 2 namely.. 1, biosafety risk management 2, Biosecurity risk management Also biorisk characterization helps to evaluate route exposure,communicability,incubation time,and infection disease. Biological risk assesment is also important because it allows a facility ,laboratory or other operation to determine the relative level of risks its different activities poses, and helps to guide in risk mitigation decision.. Lastly Bioram::::::;Biosecurity and Biosafety is a computerised risk assesment tool developed for laboratory safety and bio security risk assesment... Thank you very much maam ❤
Thank you very much ma for this interesting lecture I was able to understand that biological risk assessment is an analytical procedure designed to characterize biological risk in a facility, laboratory or unit within the potential pathogens or toxins. Risk is the likelihood of an undesirable event happening that involves a specific hazard or threat and has consequences. the first step in risk characterization is the identification of hazard and threat based upon the situation A hazard is something with the potential to cause harm. A threat is someone with the intent to cause harm Risk evaluation is a crucial step between risk characterization and taking active step towards mitigation risk.
Thank you Ma for this enlightened lecture, I appreciate your effort. After watching the video, I came to an understanding that; Biorisk characterization help us to evaluate route exposure, communicability, incubation time and infection disease. Biorisk assessment is very important as it allows a facility or operations to determine the likelihood of undesirable events, the level of the repercussions associated with the risk as well as helping to guide mitigation decision. Factors that drive different in capabilities between individuals and community are; 1. Individual factors Reputation and believe system 2. Community factors Awareness, norms and values 3. Institution factors Rules, legal issues, policies BIORAM Biosecurity and biosafety is a computerised risk assessment tool developed for laboratory safety and bio security risk assessment.
In summary, The AMP model is vital in the execution of Biorisk Management. A: The Biorisk assessment is divided into Biosafety and Biosecurity assessments. Biorisk Assessment is important because it helps one to have an idea of the gravity of the risk posed by agents in an environment. Risk is majorly influenced by two factors namely; Likelihood and Consequences. The biosafety factors and the Biosecurity factors are used in Biorisk Assessment. In risk assessment, the identification of hazards and threats is pertinent. Your accurate delivery of these topics in a concise manner is applaudable.
Thanks you ma for this lecture I learnt the risk of working in a laboratory. Risk which is the likelihood of an undesirable event happening that involved a specific hazard or threat and has consequences. Measures taken for biosafety including engineering control,personal protective equipment and for biosecurity which include doors with locks, password/ pin. The biorisk management model which compose of biorisk assessment,biorisk mitigation and biorisk performance. You discussed on biorisk assessment were you talked about it's characterization and evaluation, and how biorisk assessment is designed to characterize biological risks in a facility, laboratory or unit within it, we have two risk assessment taken biosafety risk assessment( hazards - something with the potential to cause harm) and biosecurity (threats- someone with intent to cause harm) . They are stepd taken to characterize the risk which are identifying your hazards and threats based on the situation then characterize the likelihood and consequences of the hazard and threat. A hazard or threat cannot itself pose a risk without a specific situation, and also wen characterizing biosafety and biosecurity risk the use of PPE and physical barrier can lower the likelihood of exposure and theft while vaccines and therapeutics can lower the consequences of exposure and theft respectively. Risk evaluation which is the process of determining subjectively whether a risk is high or low and whether it's acceptable or not( leading to implementation of risk mitigation measures, some factors that drives the difference in risk acceptability between institutions, communities are individuals factors ( personal preference), institution factors ( reputation, policies, rules and regulations) and community factors ( belief system, norms and values, culture) .difference between a risk averse and risk tolerance is that risk averse will spend more resources on attempting to reduce the risk it faces while risk tolerant might proceed with procedures others might find too dangerous thank you ma
Thank you ma for the impactful and self explanatory lecture. For the summary: Biorisk characterisation and evaluation are essential aspect in laboratory and facilities the deal with pathogens and toxins. Biorisk characterisation is a process to determine the likelihood an consequences of a particular risk within a risk assessment. The risk assessment help us to determine the biological risk in a laboratory. In characterizing risk assessment we have Biosafety Risk assessment (procedure design to characterize safety risk in the lab) and Biosecurity risk(procedure design to characterize security in the lab). They are 3 major step in Risk Assessment 1 identification of the hazard and threat 2 Characterizing the hazard and threat 3 the concept of relative risk These 3 major steps help in risk assessment. Risk Evaluation help you to determine if a risk is low/high, Acceptable and what can be done to mitigate it
Thanks for this great impact ma. Bio-risk assessment is the process of identifying the hazards and evaluating the risk associated with biological agents and toxins, taking into accounts the adequacy of any existing controls and deciding whether or not the risks are acceptable, bio-risk characterization is the process of determining the likelihood and consequences of a particular, well defined risk within a risk assessment.also there are certain parameters for likelihood and consequences of which bio-risk characterization helps to determine. They are as follows; Route of exposure, infectious dose, incubation time, morbidity, communicability, etc.... The difference between hazard and threat is that a hazard is something that has the potential to cause harm whereas threat is something that has an intention of causing harm. STEPS IN RISK ASSESSMENT 1. Identify the hazards and threats based on the situation. 2. Understand the concept of relative risk. 3. Characterize the hazards and threats based on likelihood and consequences. A biological risk assessment allows a facility or laboratory to determine the level of risks and help guide risks mitigation decisions so they are targeted to the most important risk. Once again thank you for breaking down this topic for me ma.

In other words it is an anlytical procedure designed to characterize security risk in a laboratory. Why do we need bio risk assessment ..it allows facility or laboratory to determine the relative level of risk ...it helps guide risk mitiation Risk is said to be the likelihood of undesirable occurence that leads to death,injury or damage Bio risk characterization and evaluation involves assessing the potential risk associated with biological agents or materials. This.process involves indentifying hazards ,evaluating the likelihood of exposure and determining the consequences of such exposure Evaluating means accessing the kmpact on health,the enviroment and biosecurity measures
❤ Thank you ma for such a simplified lecture ❤
I learnt that BioRisk characterization is the determining the process of livelihood and consequences of a well defined risk within a risk assessment
Risk assessment is an analytical procedure designed to characterize biological risk facility or other types of operation dealing with potential toxins
Also assessment covers the BIOSAFETY and BIOSECURITY risk assessment which says that BIORISK ASSESSMENT is an analytical procedure designed to characterize safety risk in the lab same with BIOSECURITY but its designed to characterize security risk in a Laboratory
Things that affect biorisk assessment are
1. Method of waste disposal
2. Duration of exposure
3. Laboratory design
Risk assessment for the identification of HAZARD AND THREATS
HAZARD: is something that is potential to cause harm while
THREAT: is someone who intends to cause harm
Thank you ma, for this great lecture on Bio risk characterization and evaluation.
I understood that a biological risk assessment is an analytical procedure designed to characterize biological risks in a facility, laboratory or unit within it, or other type of operation dealing with potential pathogens or toxins.
It comprise of Biosafety risk assessment and Biosecurity risk assessment.
Biosafety risk assessment is an analytical procedure designed to characterize safety risks in a laboratory. While Biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory.
We need biological risk assessment to allow a facility, laboratory, or other operation to determine the relative level of risk it's different activities pose, and helps guide risk mitigation decisions so that these are targeted to the most important risks.
It's objective is that the support the selection of appropriate laboratory biosafety and laboratory biosecurity risk mitigation measures to reduce likelihood and consequences of breaking into the laboratory, injuries or falling ill.
Factors relevant to biosafety are:
- Method of waste disposal
- Duration of exposure
- Virulence
- Laboratory design
- Route of exposure
Factors relevant to biosecurity are:
- Motive
- Location of laboratory
- Security of the agent
- Accessibility
- Access control
- Opportunity
Factors relevant to both are:
- Training/staff competency
- Infrastructure/equipment
- Adherence to safety measures
Risk characterization is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment.
The first step in a risk assessment is the identification of hazards and threats based upon the situation.
The next step is the characterization of the hazards and the threats based upon the likelihood and consequences.
For biosafety risks, the hazards the biological material worked with in the lab. While for biosecurity risks, the threat is an adversary aiming to acquire the biological material and use it to cause harm.
Also a hazard or threat cannot in itself pose a risk without a specific situation. Conversely, a situation also does not represent a risk without a hazard or threat. Both a changing hazard or threat and a changing situation will independently alter the scenario being assessed and the change the risk.
Another consideration in characterizing risk is the concept of relative risk.
Relative risk is the value of one particular risk( in terms of likelihood and consequences) in the context of another risk.
Risk is relative due to the fact factors that go into determining the risk are not absolute.
It is important that risk characterization process be as robust as possible.
- Comparability is the ability to trust the accuracy of differences between assessment due to similarities in their bases, assumptions, procedure and protocols.
- Repeatability is the ability to conduct the same process in the same way for the same hazard or threat and situation over a period of time or for different hazards, threat and situations at the same time.
A robust risk characterization process will generate similar results when assessing similar situation, no matter who is following the methodology, where the characterization is being conducted and when it's occuring.
One available to aid in the laboratory risk assessment is the Biosafety and Biosecurity RAM( BioRAM ).
BioRAM is a computerized risk assessment tool developed by Sandra national laboratory in partnership with the international community to facilitate laboratory biosafety and biosecurity risk assessments by simplifying risk characterization. BioRAM uses one of several possible risk assessment methodology.
Risk evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risks.
It is the process of determining subjections, whether a is high or low, and whether it's acceptable or not.
There is no systematic way of evaluating risk or to determine risk acceptability. This will depend on the perception of individual, institution and the community.
The Breakdown of bio risk characterization and evaluation was really helpful. Identifying biological agents, assessing exposure, and evaluating potential impacts were well explained. The practical insights on consequence analysis and likelihood estimation for prioritizing risks. Your emphasis on continuous monitoring and adapting strategies highlighted the importance of staying proactive. This video is fantastic resources for anyone looking to understand biorisk management
Through these lectures i was able to understand that bio risk assessment is a careful procedure made to characterize biological risks in lab
Thank you so much Prof. Again for delivering an awesome lecture on *Introduction to Risk Management Performance*
To summarize the lecture:
# The Biorisk Pyramid
The goal of biorisk management is to identify and reduce risks before they evolve into near misses or incidents. The pyramid consists of:
1. Harmful incidents (e.g., laboratory-acquired infections)
2. Near misses (e.g., improper PPE use)
3. Unsafe and insecure conditions (e.g., inadequate biorisk training)
# Performance in Biorisk Management
Performance refers to how well a biorisk management system functions to manage or minimize biorisk. Characteristics of BRM system performance:
- Result of all activities and efforts of all people in a facility
- Actual performance may not match planned levels
- Performance measurement assesses differences and changes over time
# Benefits of BRM Performance
1. Determines which parts of the BRM system meet stated goals or benchmarks
2. Provides a demonstrable record of system performance
3. Supports facility certification/accreditation
4. Identifies areas for improvement
5. Provides assurance that risk is acceptable
6. Facilitates maintenance and sustainability of the system
7. Can save money and time
8. Helps prevent incidents
# Key Points
- Mitigation is not perfect; implementing one mitigation measure alone has weaknesses
- Multiple mitigation measures can reduce risk likelihood but not eliminate it
- Performance measurement is crucial to assess BRM system effectiveness
# Performance Scenario
A waste transport disposal company employee contracted tuberculosis from biohazard bags from a local TB reference laboratory. Investigation revealed performance issues, including missing records and inadequate storage of autoclave printer records.
# Potential Measurement Methods
1. Audits and inspections
2. Performance indicators
3. Observations
4. Interviews
5. Surveys and questionnaires
THANK YOU MA FOR SUCH A SIMPLIFIED AND WELL EXPLAINED LECTURE.
I LEARNT SO MUCH.
WHAT IS RISK:Risk is the likehood of an undesirable event happening that involves a specific hazard or threat and has consequences.
I learnt that BIORISK CHARACTERIZATION is the process of determing the likehood and consequences of a particular well defined risk within a risk assessment.
The lesson also showed that there are certain parameters of likehood and consequences of which BIORISK CHARACTERIZATION helps to determine route of exposure.
I also learnt that BIORISK ASSESSMENT which is an analytical procedure designed to characterize biological risks in a laboratory with potential pathogens,to determine the likelihood and consequences.The risk is characterized as BIO SAFETY RISK ASSESSMENT and BIO SECURITY RISK ASSESSMENT.
Also I learnt why we need bio risk assessment because it allows a laboratory to determine the RELATIVE level of risk it's different activities pose.
The difference between HAZARD and THREAT is that hazard is something that has the potential to cause harm whereas threat is someone that has an intent of causing harm
RISK EVALUATION: This is the process of determining, subjectively, whether a risk is high or low and whether its acceptable or not.The evaluation of risk is highly related to the concept of RISK ACCEPTANCE.
There is no systematic way of evaluating risk or to determine risk acceptability.This will depend on the perception of individuals, institutions and the community.

SUMMARY ON BIORISK CHARACTERIZATION AND EVALUATION
A biological risk assessment is an analytical procedure designed to characterize biological risk in a facility, laboratory or unit within it.
Biosafety risk assessment is an analytical procedure designed to characterize safety risks in a laboratory.
Biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory.
A biological risk assessment allows a facility or laboratory to determine the relative level of risk it's activities poses and helps guide risk Mitigation decision so that these are targeted to the most important risk.
*Risk assessment* is a process that characterize a particular situation in order to determine the likelihood and consequences of a certain adverse event( Risk Characterization) and supports decision making regarding the acceptability of the risk ( Risk Evaluation).
*Risk Characterization* is the actual process of determining the likelihood and consequences of a particular risk within a Risk Assessment.
The first step in a rush assessment is the *Identification* of hazard and threats based on the situation.
The next step is the *Characterization* of hazards and threats based on likelihood and consequences.
A *Relative Risks* is the value of one particular risk( in terms I'd likelihood and consequences) in the context of another risk. Understanding the relative risk associated with different situations or by implementing different risk mitigation strategies is important for the overall process of Characterizing risk.
It is important that the risk Characterization process be as Robust as possible so that it will generate similar results when assessing similar situation and where the Characterization is occuring.
*BioRAM*(Biosafety and Biosecurity RAM) is a computerized risk assessment tool developed by *Sandia National Laboratory* in partnership with *International Community* to facilitate lab biosafety and biosecurity risk assessment by simplifying risk Characterization.
The BioRAM tool helps determine the relative risk levels in a comparable and repeatable way.
*Risk Evaluation* is a crucial intermediary step between risk Characterization and taking active steps towards mitigation risk. The evaluation of risk is highly related to the concept of *Risk acceptance* .
There is no systematic way of evaluating risk or to determine risk acceptability. This will depend on the perception of individuals, institution and communities.

- Risk evaluation -: Is the process of determining, subjectively, whether a risk is high or low and whether it is acceptable or not. The evaluation of risk is highly related to the concept of risk acceptance.
- The varying abilities of individuals and communities to manage these risks are influenced by several factors like:
- 1). Personal beliefs and reputation
- 2). Influence of institutional regulations, legal standards and policies.
- 3). The awareness, Norma and values present within the community.
To add to this, BIO RAM is a digital toolused for conducting comprehensive biosecurity and biosafety risk assessments in laboratory environments.

Thanks Ma for this wonderful lecture, In this lecture I learnt that biorisk characterization is the process of determining the likelihood and consequences of a particular risk within a risk assessment and the first step in ris assessment is the identification of(i )Hazards and (ii) Threats based on the situation. I also understand that Risk evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risk.
And in characterizing risk under biosafety you have to adhere to;
1.The use of PPE can lower the likelihood of exposure
2.Vaccines can lower the consequences of exposure while under biosafety
3.The use of physical barriers aids in lowering the likelihood of theft
4.The availability of therapeutics can lower the consequences of Malicious release
Thanks so much mar for the wonderful lecture, I learnt that:
Biorisk characterization identifies the likelihood and consequences of biological risks through systematic assessment.
Key Areas of Risk Assessment:
Biosafety: Ensures lab safety by managing hazards (e.g., toxins, pathogens).
Biosecurity: Focuses on preventing unauthorized access or misuse of biological materials.
Factors Influencing Biorisk:
1. Waste disposal methods.
2. Exposure duration.
3. Laboratory design
Hazards vs. Threats:
Hazard: A potential source of harm.
Threat: Intentional actions to cause harm.
Effective risk management ensures safety and security in biological operations.

BIO RISK MANAGEMENT consists of assessment, mitigation and performance
BIO RISK ASSESSMENT is an Analytical procedure designed to characterize biological risk in a facility,lab or unit within it, or other type of operation dealing with potential pathogens or toxins
BIOSAFETY RISK ASSESSMENT
BIO SECURITY RISK ASSESSMENT is an analytical procedure designed to characterize security risk in a lab .
WHY WE NEED A BIOLOGICAL RISK ASSESSMENT
we need it because it follows a facility lab or other operation to determine the relative level of risk
It’s different activities pose and helps to guide risk mitigation decisions so that these are targeted to the most important risks.
RISK ASSESSMENT MANAGER is a process that characterizes a particular situation in order to determine the likelihood and consequences of a certain adverse event ( risk characterization) and support decision making regarding the acceptability of the risk (risk evaluation)

Thank you ma
This is one of the best lectures I’ve ever watched by Dr. Iya Eze Bassey, an associate professor of chemical pathology at the University of Calabar
I appreciate the effort you put in to make this lecture as understandable as possible. Bio risk management is a system of processes to control safety and security risks associated with handling biological agents and toxins.
This lecture also explains the importance of having a good bio risk management system in place, as it can help to reduce the risk of accidents and injuries. You then go on to discuss the different components of a bio risk management system, including assessment, mitigation, and performance.
There’s also some examples of how a bio risk management system can be implemented in a laboratory setting.
In a nutshell
Risk is the likelihood of an undesirable event happening that involves a specific hazard or threat and has consequences.
Bio risk management is a system of processes to control safety and security risks associated with handling biological agents and toxins."
Bio risk management is important because it can help to reduce the risk of accidents and injuries.
This is a well explained lecture on Bio risk characterization and evaluation
Thank you for this simplified lecture.
Through this lecture,I have learnt that Bio risk characterization is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment.
In characterizing risk under biosafety you have to adhere to this;
-The use of PPE can lower the likelihood of exposure.
Risk evaluation is the process of determining subjectively whether a risk is high or low,and it is hugely related to the concept of risk acceptable.It is also a crucial intermediary step between risk characterization and taking active steps towatds mitigating risk.
Note:It is important to note that precise location of the risk tolerance curve on the graph is fact arbitary and it's the essence of risk evaluation.
Thank you ma for this wonderful lecture.
Below is the summary of what i learnt
Risk is the likelihood of an undesirable event to happen which involves a specific hazard or threat that has consequences.
Risk of working in a lab with biological materials include: Infections,injuries,air pollution,disabilities,other health hazards and death.
Futhermore Bio-safety risk + Bio-security risk equals Bio risk.
Biorisk is the risk associated with biological materials in the laboratory.
Bio safety addresses the unintentional exposure to bio hazards ensuring protection and general safety. Bio security defends against intentional theft or misuse of biological agents.
Measures for bio-safety:
Engineering controls,good laboratory work pratices,personal protective equipment (PPE) and practices and procedures.
Measures for bio security:
Doors with locks,biometrics,information security,alarms etc.
Key component of bio risk management:
1.)Bio risk assessment
2.)Bio risk mitigation
3.)Performance
It is called the AMP model.
Bio risk assessment is the process of identifying hazards and evaluating risk.
Bio mitigation is the action or control measures to reduce risk associated with biological materials.
Performance is the simply the implementation of the entire bio risk management system.
Biorisk management system is a set of system that is used for reducing safety and security risk.
Advantages of good management system:
1.)condusive and safe environment
2.) Enhanced organizational performance et
Thank you ma'am the lecture was very interesting I learnt that, Biorisk characterization and evaluation are critical components of biorisk management. Here's an overview:
*Biorisk Characterization*
Biorisk characterization involves identifying and describing the biological agents, toxins, or other hazardous materials that could pose a risk to humans, animals, or the environment.
*Factors to Consider*
1. Agent characteristics: Pathogenicity, virulence, infectivity, and toxicity.
2. Route of exposure: Inhalation, ingestion, skin contact, or injection.
3. Dose-response relationship: The relationship between the dose of the agent and the resulting harm.
4. Stability and persistence: The agent's ability to survive and remain infectious outside of a host.
*Biorisk Evaluation*
Biorisk evaluation involves assessing the likelihood and potential impact of a biorisk event.
*Risk Assessment Methodologies*
1. Qualitative risk assessment: A subjective evaluation of the risk based on expert judgment.
2. Quantitative risk assessment: A numerical evaluation of the risk based on statistical models and data.
3. Semi-quantitative risk assessment: A combination of qualitative and quantitative approaches.
*Risk Evaluation Matrix*
A risk evaluation matrix is a tool used to evaluate the likelihood and potential impact of a biorisk event. The matrix typically consists of a grid with likelihood on one axis and impact on the other.
*Risk Categorization*
Based on the risk evaluation, biorisks can be categorized into different levels of risk, such as:
1. Low risk: Unlikely to occur and with minimal impact.
2. Moderate risk: Possible to occur and with moderate impact.
3. High risk: Likely to occur and with significant impact.
4. Extremely high risk: Almost certain to occur and with catastrophic impact.
By characterizing and evaluating biorisks, organizations can develop effective strategies to mitigate and manage these risks, ensuring the safety and security of their personnel, facilities, and the environment.
Thank you very much for this lecture I learnt that risk is a likehood of an undesirable event happening that involves a specific hazard or threats and has consequences
And I learnt that bio risk characterization is the process of determining the likelihood and consequence of a particular well defined within a week's assessment.
The lesson also showed that they are certain parameters of likelihood and consequence of which bio risk characterization helps to determine root of exposure.
Also I learnt why we need bio risk assessment. Because it allows a laboratory to determine the relative level of risk it's different activities pose. The difference between hazard and threat is that hazard is something that has the potential to cause harm whereas threat it's someone that has a intent of causing harm.
Overall risk evaluation plays a vital role in ensuring that risk are understood and appropriately managed contributing to safer environment in various context from healthcare to environmental policy
With all these I've got to get a clear vision on what I learnt to the area thank you very much ma god bless🙏
Thank you so much ma for this wonderful lecture
It has been said that a biological risk assessment is an analytical procedure designed to characterize biological risk in the laboratory facility or unit dealing with potential pathogens or toxins.
In other words, it is designed to characterize the security risk in the laboratory.
Why do we need bio-risk assessment?
It allows a facility or laboratory to determine the relative level of risk,
It helps to guide risk mitigation
RISK:also said to be the likelihood of undesirable event that occurs resulting to injury,death, hazard and damage etc
Bio-risk characterization an evaluation also involves assessing the potential risk associated with biological agents or materials.
This process is involved identifying hazards evaluating the likelihood of exposure and determining the consequences of such exposure.
The key points of bio-risk include understanding the nature of biological agents,it's pathogenity and the routes or transmission.Evaluation involves assessing the impaction on human health and the environment and biosecurity measures.
Note:the term HAZARD is used in biosafety while threat is used in biosecurity
Thanks again Dr for the information lecture, its really enlightening .
WHAT IS RISK:Risk is the likehood of an
undesirable event happening that involves a specific hazard or threat and has consequences.
I learnt that BIORISK CHARACTERIZATION is the process of determing the likehood and
consequences of a particular well defined risk within a risk assessment.
The lesson also showed that there are certain parameters of likehood and consequences of which BIORISK CHARACTERIZATION helps to determine route of exposure.
I also learnt that BIORISK ASSESSMENT which is an analytical procedure designed to characterize biological risks in a laboratory with potential pathogens,to determine the likelihood and
consequences. The risk is characterized as BIO SAFETY RISK ASSESSMENT and BIO SECURITY RISK ASSESSMENT.
Also I learnt why we need bio risk assessment because it allows a laboratory to determine the RELATIVE level of risk it's different activities
pose.
The difference between HAZARD and THREAT is that hazard is something that has the potential to cause harm whereas threat is someone that has an intent of causing harm
RISK EVALUATION: This is the process of determining, subjectively, whether a risk is high or low and whether its acceptable or not. The evaluation of risk is highly related to the concept of RISK ACCEPTANCE.
There is no systematic way of evaluating risk or to determine risk acceptability. This will depend on the perception of individuals, institutions and the community.
Thank you so much ma.

Another fine lecture yet again, thank you for breaking down
In summary, I learned that:
* Biological risk assessment is a process to identify, evaluate, and control biological hazards.
* It helps determine the potential risks associated with working with biological materials.
* Key factors influencing biological risk include the nature of the biological agent, the potential for exposure, and the severity of the potential consequences.
* The assessment process involves characterizing the hazard, assessing the likelihood and consequences of exposure, and evaluating the overall risk.
* Effective risk mitigation strategies can be implemented based on the assessment findings.
* Best practices for biological risk assessment include using a robust and repeatable process, considering the relative risk of different exposures, and communicating the results to stakeholders.
Thank you Ma for the lecture, I understood that:
A biological risk assessment is an analytical procedure designed to characterize biological risk in a facility, laboratory or unit within it.
Biosafety risk assessment is an analytical procedure designed to characterize safety risks in a laboratory.
Biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory.
Why we do Biological Risk Assessment:
1.It helps a Laboratory or facility to determine the relative level of risk its different activities poses and helps guide risk mitigation decisions.
Risk Characterization: is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment.
The BioRAM tool helps determine the relative risk levels in a comparable and repeatable way.
The objective of this lessons is to understand the risk characterization and evaluation processes within biological risk assessment.
NOTE: when working in the laboratory you work with a lot of risk. So it's key to understand this concept .
Risk is the likelihood of an undesirable event happening, that involves a specific hazard or threat and has consequences.
Biological risk assessment allows a facility, laboratory, or other operations to determine the relative level of its risk different activities pose, and helps guide risk mitigation decisions so that these are targeted to most important risks.
Risk characterization:
Identification: identify biological agents that pose risks.
Assessment: determine the likelihood and extent exposure to biological agents.
Risk evaluation: calculate the likelihood and potential impact of side effects.
Risk comparison: compare the estimated risk to set standard.
Thanks ma'am for your time and effort
Thank you very much ma for this wonderful lecture
With this lecture I have understood the crucial aspect of evaluating biological risk .In total summary biorisk characteriszation and evaluation involves
1 identifying and assessing biological risk.
2 Determining the likelihood and potential impact on risk.
3 Evaluating the effectiveness mitigation strategies
4 Monitoring and reviewing biorisk management performance
With this explanation I now understand how to evaluate biological risk and development effective mitigation strategies
Thank you so much ma for this lecture
In summary I have learnt that Bio risk mitigation involves strategies and measures implementation to prevent reduce or control risks associated with biological agents or toxins in research healthcare and other settings.
The five categories of mitigation control methods include.
1 Elimination and substitution.
2 Engineering control.
3 Administrative control.
4 Practices and procedures.
5 Personal protective equipment ( PPE )
Bio risk mitigation strategies involve biosafety and biosecurity measures to prevent accidental or intentional exposure to hazardous biological agents or toxins .
In conclusion the aim of biorisk management is to prevent biological accident, minimize the spread of disease and maintain safe materials for work
The Breakdown of bio risk characterization and evaluation was really helpful. Identifying biological agents, assessing exposure, and evaluating potential impacts were well explained. Bio risk characterization help us to evaluate route exposure, communicability, incubation time, and infection disease.
I also learnt that BIO RISK EVALUATION and
CHARACTERIZATION modifies pathogens, toxins and genetic materials, it also expose biological agent that can cause gems.
There are factors that drive different in capabilities between individuals and community are
1. Community awareness, norms, and values.
2. individuals reputation and believe system
3. Institution rules, legal issues, policies.
Through these lectures i was able to understand that bio risk assessment is a careful procedure made to characterize biological risks in lab
Thanks once again ma’am as it gets more clearer as we advance in each lessons.
IN SUMMARY;
BIO Risk characterization and Evaluation is the process of assessing the potential risk associated with biological agents such as pathogen, toxins and genetically modified organisms. it involves identifying hazard,threat and vulnerabilities determine the likelihood and potential impact of adverse events
Hazard refers to the intention of biological agents that can cause germs , while threat refer to the intention use these agent for malicious purpose. BIO RAM (biological risk assessment and management) is a frame work used to guide the very process considering factors such as exposure routes and mitigation strategies
What factors might drive different in risk capabilities between individuals , institution and communities
Institution ---funding, reputation, belief system
Institution ---legal issues,polices, rules and regulations
Community factor ---community awareness,norms ,and values
Risk assessment:
This a process that characterize a particular situation in order to determine the likelihood and consequences of a certain adverse event( Risk Characterization) and supports decision making regarding the acceptability of the risk ( Risk Evaluation).
Risk Characterization:
It is the actual process of determining the likelihood and consequences of a particular risk within a Risk Assessment.
The first step in a rush assessment is the Identification of hazard and threats based on the situation.
The next step is the Characterization of hazards and threats based on likelihood and consequences.
A Relative Risks:
This is the value of one particular risk( in terms I'd likelihood and consequences) in the context of another risk. Understanding the relative risk associated with different situations or by implementing different risk mitigation strategies is important for the overall process of Characterizing risk.
One further point i noted from the video is that It is important that the risk Characterization process, should be as Robust as possible so that it will generate similar results when assessing similar situation and where the Characterization is occurring.
Bio RAM also known as Bio safety and Bio security RAM is a computerized risk assessment tool developed by Sandia National Laboratory in partnership with International Community to facilitate lab bio safety and bio security risk assessment by simplifying risk Characterization.
The Bio RAM tool helps determine the relative risk levels in a comparable and repeatable way.
Risk Evaluation is a crucial intermediary step between risk Characterization and taking active steps towards mitigation risk. The evaluation of risk is highly related to the concept of Risk acceptance .
There is no systematic way of evaluating risk or to determine risk acceptability. This will depend on the perception of individuals, institution and communities.
Am grateful for this shared knowledge. I enjoyed the tiger scenerio you used, your the best.
Thank you Ma for the detailed explanation. Here is what I learnt from this lecture:
Risk characterization in biosafety is essential for assessing exposure routes, communicability, incubation periods, and infectious diseases. Through this process, I have gained an understanding of how to identify and assess emerging biological risks in laboratory settings. It also involves evaluating and modifying pathogens, toxins, and genetic materials, which can expose biological agents that may pose serious health risks.
The varying abilities of individuals and communities to manage these risks are influenced by several factors: 1) the awareness, norms, and values present within the community
2) personal beliefs and reputations, and
3) the influence of institutional regulations, legal standards, and policies. Additionally, BIO RAM is a digital tool used for conducting comprehensive biosecurity and biosafety risk assessments in laboratory environments.
Thank you mar for the wonderful lecture.
I learned about biorisk characterization and evaluation.
Where you defined the following terms:
Biorisk assessment: it is an analytical procedure designed to characterize biological risk in a facility, laboratory or unit within it, or other types of operations dealing with potential pathogens or toxins. Under which you elaborated on;
Biosecrity risk assessment which is an analytical procedure designed to characterize security risk in the laboratory.
Biosafety risk assessment which is an analytical procedure designed to characterize safety risk in the laboratory.
I learned that biological risk assessment enables a facility, lab, or other operations to determine the relative level of risk its different activities pose, and help guide risk mitigation decisions so that these are targeted to the most important risk.
Risk it is the likelihood of an undesirable event happening that involves a specific hazard or threats and their consequences.
Risk assessment is the process and procedure that characterize a particular situation in order to determine the likelihood and consequences of a certain adverse avent ( risk characterization) and support decisions regarding the acceptablility of the risk .
Risk characterization is the actual likelihood of determining the likelihood and consequences of a particular risk within a risk assessment.
Risk evaluation is the process of determining subjectively weather a risk is high or low, and weather its acceptable (proceed with work) or not(leading to implementing risk mitigation measures).
Thank you Dr. for the wonderful lecture.
Biorisk Evaluation and characterization is determining the process of livelihood and consequences of a well defined risk within a risk assessment is an analytical procedure designed to characterize biological risk facility or other types of operation dealing with potential toxins, also the assessment covers the biosafety and biosecurity assessment.
factors that affect biorisk assessment
method of waste disposal

laboratory design
risk evaluation is the process of determining subjectively whether a risk is high or low and acceptable or not. the evaluation of risk is highly related to the concept of risk acceptance, however, there is no systematic way of evaluation risks or to determine risk acceptability, this depend on individuals perception, institutions, and the community.
Before my summary, may I request your permission to appreciate you for taken time to give us an explicit lecture on the:
Topic: Biorisk characterization and Evaluation.
I was able to understand the following:
1. Biological risk assessment.
2. Introduction: A biological risk assessment is an analytical procedure designed to characterize biological risk in facility, laboratory or unit within it. Or other type of dealing with potential pathogens or toxins.
Biorisk characterization and evaluation entail a systematic approach to identifying, assessing, and mitigating biological risks associated with pathogens or toxins in facilities, laboratories, or units. The primary objective is to ensure biosafety and biosecurity.
1. *Biological Risk Assessment*: A structured process to identify, evaluate, and characterize biological hazards, considering factors like pathogen virulence, transmission routes, and potential consequences.
2. *Risk Characterization*: Quantitative or qualitative analysis of the likelihood and potential impact of biological risks, informing decision-making and resource allocation.
*Biological Risk Assessment Phases*
1. *Hazard Identification*: Recognize potential biological hazards (pathogens, toxins).
2. *Risk Assessment*: Evaluate likelihood and potential consequences.
3. *Risk Characterization*: Combine hazard and risk assessments to prioritize mitigation strategies.
4. *Risk Management*: Implement controls, monitor, and review.
*Things to consider
1. Facility design and ventilation
2. Standard Operating Procedures
3. Personal Protective Equipment
4. Biosafety levels
5. Biosecurity measures (access control, surveillance)
*Benefits*
1. Enhanced biosafety and biosecurity
2. Reduced risk of accidents and exposures
3. Compliance with regulations and guidelines
4. Improved public health and environmental protection.
Once again thank you very much Prof.
Thank you prof for this insightful lecture.
In summary:
Biorisk evaluation is a systematic process designed to categorize biological threats within laboratory settings or specific units. This comprehensive risk evaluation is bifurcated into biosafety risk evaluation and biosecurity assessment. Conducting a thorough biorisk evaluation is crucial, as it enables facilities or operations to ascertain the probability of adverse events, gauge the severity of potential repercussions, and inform strategic decisions for mitigation.
The risk evaluation process comprises the following steps:
1. Identification of potential hazards and threats
2. In-depth characterization of hazards and threats, considering underlying causes and consequences
3. Relative risk assessment
Two essential tools facilitating laboratory risk evaluation are Biosafety and Biosecurity Risk Assessment Matrix (Bio RAM). By streamlining risk characterization, Bio RAM enables a more efficient evaluation process. Risk evaluation serves as a critical intermediary step, bridging the gap between risk characterization and proactive mitigation measures.
Several factors influence variations in risk tolerance, including:
1. Individual factors
2. Community factors
3. Institutional factors
Thank you ma.
Thank you very much ma for this lecture.
IN SUMMARY:
I understood that Biorisk characterization and evaluation is the process of accessing the risk associated with biological agents such as genetically modified organisms (GMOs), etc.
The goal of Biorisk characterization and evaluation is to: Evaluate the potential impact or consequences, To develop strategies for risk mitigation and management, To assess the likelihood of adverse effects, To identify potential hazards.
Biorisk characterization and evaluation are critical in various areas including:
1. Agriculture: Assessing the risk of plant or animal diseases
2. Public health: Assessing the risk of infectious diseases or pandemics pandemics
3. Biosafety and Biosecurity: Developing strategies to prevent or migrate biological threats
4. Environmental risk assessing: Evaluating the potential impact of biological agents on ecosystem.
Biorisk assessment is an analytical procedure designed to characterize security risk in a laboratory, it's factors include:
1. Security of agents
2. Accessibility
3. Access control
4. Location of lab
Thank you for this interesting lecture Ma it has help me understand that biorisk assessment is an analytical procedure designed to characterize biorisk in a facility, laboratory or unit within it, or other type of operation dealing with potential germs or toxins
Biorisk assessment helps determine the relative level of risk its different activities poses in the lab and also helps guide risks mitigation decisions so that there are targeted to the most important risk.
The aim of biorisk assessment is to determine the likelihood and the consequences of adverse event and support decision making regarding the acceptability of the risk.
In brief, Dr. lya Eze Bassey, your session on
bio-risk characterization and evaluation left a
strong impression. I appreciate your effective
approach to simplifying risk identification and
mitigation. The breakdown of key steps, such as
outlining activities, recognizing threats, and
balancing risk with research goals, is particularly
valued. This knowledge is crucial for making
informed decisions and prioritizing safety in our
work. Thank you for sharing your expertise and
making the session impactful After the lecture,
learned that boorish characterization and
evaluation is a systematic and scientific way to
figure out the risks of biological agents. It helps
us decide what actions to take to manage those
risks.
Thank you Ma for this wonderful lesson
I learnt about Risk Characterization which is the first step in risk assessment and is seen as the actual process of determining consequences of a particular risk within a risk assessment.
Here, work activities are described, hazards & any threats are identified, also, risks are identified.
In this first step, characterization of hazards & threats are based upon the likelihood & consequences.
For hazards, likelihood of hazards to cause harm and the extent of the harm are considered.
And for threats, likelihood of threats to successfully achieve their goal & the consequences of the goal are considered.
I noted that a hazard or threat can't pose a risk without a specific situation & vice versa.
Biological Risk Assessment which is an analytical procedure designed to characterize biological risks in a facility, laboratory or unit within it, or other type of operation dealing with potential pathogens or proteins.
Biosafety Risk Assessment: is an analytical procedure designed to characterize safety risks in a laboratory.
Biosecurity Risk Assessment: is an anayltical procedure designed to characterize security risks in a laboratory.
The Need For Biorisk Assessment which is to determine the relative level of risk a laboratory, facility or operation's different activities pose, and helps guide risk mitigation decisions so dat these are targeted to the most important risks.
Risk assessment being a process that characterizes a particular situation in order to determine the likelihood & consequences of a certain adverse event (risk characterization), and supports decision making regarding the acceptability of the risk( risk evaluation)
The Objective of Risk Assessment which is to support the selection of appropriate lab biosafety & laboratory biosecurity risk mitigation measures to reduce likelihood and consequences of inner injury, falling ill sickness or break-ins (causing problems).
Biorisk Factors That Affect Biorisk Assessment:
-Method of waste disposal.
-Duration of exposure.
-Virulence in substances(highly infectious malignant or deadly substances).
-Laboratory design.
-Route of exposure.
Biosecurity Factors That Affect Biorisk Assessment:
-Motive of bad individuals.
-Location of laboratory.
-Security of the laboratory agents.
Biosecurity & Biosafety Factors Affecting Biorisk Assessment:
-Training/Staff competency.
-Infrastructure/Equipment
-Adherence to safety measures.
When Characterizing risk:
-Risk characterization process must be robust(i.e alot)
-It must be comparable
-It must be repeatable.
I got to know about Biosafety & Biosecurity RAM [BioRAM], a computerized R.A tool developed to aid in laboratory risk assessment.
Risk Evaluation which is the 2nd step in risk assessment is highly related to the concept of risk acceptance or acceptable risk. This is the process of determining subjectively whether a risk is high or low and whether it is acceptable (which leaves us to proceed with the work) or not to (leading us to implement risk mitigation measures). It is a crucial intermediary step between risk characterization & taking active steps towards mitigating risk.
Factors That Drive Differences In Risk Acceptability Include:
-Individual Factors which involve personal preferences, belief systems, reputation, funding.
-Instutution Factors which include reputation, legal issues, funding, infrastructure, management, commitment, policies, rules & regulations.
-Community factors which include community awareness, norms & values, belief systems, culture educational advancement, benefits, political & community interest, loss & damage.
I noted that only an institution can determine whether a risk is very high, high, moderate, low and very low.
I also learnt about the Risk Evaluation Graph which contains the risk tolerance curves plotted against likelihood & consequence.
With risk averse (those who don't like risks) graph slightly different from the risk default graph, and the risk tolerant (those who accept risks) graph being much more different from the risk default graph and risk averse graph.
Likelihood Adverse Institutions which are focused only on the potential (likelihood) of something bad happening but less concerned about specific level consequences.
And
Consequence Adverse Institutions which are focused about consequences, regardless of the potential for an occurrence.
Thanks for the wonderful lecture. Summary of what i learnt are as follow. Firstly i learnt biological risk risk assessment as analytical procedure design to charactise biological risk in an operation dealing with pathogens or toxins. A biosafety risk assessment is an analytical procedures in laboratory. Also biosecurity assessment which entains analytical procedures design to characterised security risk in lab. I learnt the level of repercussion associated with the risk as well as helping to guide mitigation decision. The steps involved in risk evaluation are. 1 identification of the hazards and treat. 2 characterisation of the harzard and treat. 3 Relative risk. Risk evaluation is crucial termediary step between risk characterisation and active steps taking towards risk mitigation. It weather the risk is low or high and if it acceptable or not. They are certain factors driving difference in risk acceptance they include 1 1 1individual factor. 2 Community factor. 3 institution factors. Thanks for the wonderful lecture.
This video thoroughly explains bio risk management, it's models, the need for bio risk assessment, risk evaluation and the benefits that comes with it.
Firstly, bio risk assessment is an analytical procedure designed to characterize biological risks in a facility within it. This assessment covers both bio safety and bio security risk assessment. The former is an analytical procedure designed to characterize safety risks in a lab, while the latter is an analytical procedure designed to characterize security risks in a lab.
>>The need of bio risk assessment allows a facility to determine the relative level of risks it's different activities pose, and helps guide risk mitigation decisions so that these are targeted to the most important risks.
I have also come to understand that risk assessment can be said to be a process that characterizes a particular situation in order to determine the likelihood and consequences of a certain event.
First step in a risk assessment is the ability to identify the hazards based upon the situation. The term hazard is used in the bio safety context, and threat is used in the bio security context.
~Risk evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risks. It determines whether a risk is high or low.

In summary of what I learnt about Biorisk Characterization
Biorisk assessment is an analytical procedure designed to classify biological risk in a facility, laboratory or unit within it .
Biorisk assessments is divided into two
Bio safety risk management
Bio security risk management
I also learnt that Biological risk assessment is a very important because it allows a laboratory or operation to determine the relative level of risk in it’s different activities pose , it also helps to guide risk mitigation decisions.
WHAT IS RISK : I also learnt that risk is the likelihood of an undesirable event happening that involves a specific hazard or threat and has consequences. I also learnt that the first step in a risk assessment is the identification of HAZARD AND THREAT. Hazard is something with the potential to cause harm, it’s used in the Biosafety context while Threat is someone with intent to cause harm and it’s used in the Biosecurity context.
STEPS INVOLVED IN RISK EVALUATION
1:Identification of the hazard and threat
2:Relative risk
Ma I also learnt that one of the available tools to aid in the laboratory risk assessment is the BIOSAFETY AND BIOSECURITY RAM (BIO RAM ) . BioRam is a computerized risk assessment tool developed by sandia natural laboratory, it achieves this by simplifying risk characterization.
I also learnt about Risk Evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigation risk.
Certain factors driving difference in risk are
1:community factors
2:individual factors and
3:institution factors.
Thank you ma ❤.
Thank you so much Dr Iya Eze.
I understood the breakdown of bio risk characterization and evaluation, also identifying biological agents, evaluating potential impacts and assessing exposure were well explained. The practical insights on consequence analysis and likelihood estimation for prioritizing risks. You emphasized on continous monitoring and adpating stategies highlighted the importance of always staying proactive. Due to your always detailed explanation i was able to understand that Bio Risk. assessment is a careful procedure made to characterise biological risks in the laboratory.
There is no systematic way of evaluating risk or to determine risk acceptability. It's all about the perception of the institution or individual and even communities.
I learnt that Biorisk characterisation and Evaluation is the process of assessing the potential risk associated with biological agents such as pathogen,toxins and genetically modified organisms.This involves identifying hazard threat and vulnerabilities to determine the likelihood and potential impact of adverse events.
Hazard refers to the intention of biological agents that can cause germs, while threats refer to the intention of using these agents for malicious purposes.BIO RAM (biological risk assessment and management) is a framework used to guide the very process considering factors such as exposure routes mitigation strategies
What factors might drive different in risk capabilities between individuals, institution and communities;
Institution---funding, reputation,belief system
Institution----legal issues,polices, rules and regulations
Community factor---community awareness,norms, and values and many more..thank you Ma
I recommend every one hungry for knowledge to watch these videos from Dr. Iya Eze Bassey.
A biological risk assessment is all about procedures that characterize biological risk in the laboratory, facilities or operations dealing with potential pathogens.
Biosecurity risk assessment characterize security risk in a laboratory.
Biosafety and Biosecurity RAM is one of the tools that aid risk assessment in the laboratory.
Thank you so much ma'am.
Thank you ma for yet another educative and insightful lecture.
In summary biorisk assessment is an analytical procedure designed to characterise biological risk in a laboratory, facility, unit or any other type of operation dealing with pathogens or toxins. Risk management is designed to characterise safety risk in laboratory. The main goal of risk assessment is to support the selection of appropriate laboratory bio safety and bio security risk mitigation measures so as to reduce any consequences or likelihood ( weather hazards or threats).
Biorisk characterization and evaluation goal is to ensure the safe handling, storage and use of biological materials and to prevent or minimize the risk of adverse effects on human health, the environment and economy.
Thank you ma for the superb lecture
Summary of what i learned
Biohazard Risk Assessment is a systematic process
to identify, evaluate, and control biological risks
in a laboratory setting. It involves determining
the likelihood and potential consequences of a
specific biohazard, such as a pathogen or toxin. By understanding the risks, laboratories can implement appropriate safety measures to protect personnel,the environment, and the public.
I gained a better understanding of the dangers of working in a laboratory that handles biological materials thanks to this video, which also explained what risk and biorisk are, what they mean, and what precautions to take. It allows me to comprehend and provides solutions to all the important questions of biosafety and biosecurity, which are all about management. I gained knowledge about biorisk management systems and the components of an effective management system.
Good day ma and Thank yoy for this Wonderful Insights on Bio risk Characteristics and Evaluation. i learnt a Lot o things which Includes that Biological Risks assessment is an Analytical procedure designed to Characterised Biological risks in a laboratory or other Type of Operation dealing with Potential toxins. Biosafety risk assessment has to do with safety risks in a Laboratory while Biosecurity risks assessment has to do with the Security risks in a Laboratory. Risk assessment helps reduces the Likelihood and Consequences of Injury, Sickness etc in the Lab. The first step in risks assessment is being able to identify the Hazards and Threat, the Hazards has to do with something with the Potential to cause harm while the threat has to do with and Individual with the Motive to cause Harm.
I must confess that this is one of the best lectures I have had in my life, God bless u for the wonderful section. Ma, at the end of the video I was able to pick out the following points:
Firstly, I learned that biorisk characterization and evaluation are the basic tools for risk assessment, and risk characterization has to do with the process of determining the likelihood and consequences of a particular risk happening within a risk assessment, whereas risk evaluation has to do with a crucial intermediary step between characterization and taking action towards mitigation decisions.
Secondly, I learned that before a risk can be characterized, it should be first of all assessed by identifying the hazards or threat that is involved in that particular risk, and this characterization could be a biosafety characterization in which the hazardnis a biological agents or a biosecurity characterization in which the hazard could be an adversary aiming to acquire the biological material and use it to cause harm.
Thirdly, I also came to the realization that for the biorisk assessment to be achieved, they are certain tools that need to be put in place. E.g of such tools are the biosafety and biosecurity RRM ( BioRAM) . Which is a computerized assessment tool that was developed by the Sandi national laboratories in partnership with the international community to facilitate laboratory biosafety and biosecurity assessment.
Finally, with the knowledge I have gotten from the lecture, I can now boldly say without any doubt, that risk assessment helps us to characterize our risk, evaluate it, and decide whether or not the risk is acceptable.
God bless you ma for the video, we are so much grateful and we pray u do more videos for us ... 🙏🥰💕🙏
'' Biorisk characterization and evaluation " .
I learnt that biorisk characterization is the process of determing the likelihood and consequences of a particular,well defined risk with in a risk assessment.
I also know the difference between hazard and threat is that hazard is something that has the potential to cause harm where as threat is someone that has an intent of causing harm .
I learnt that there is no systematic way of evaluating risk because it usually depends on individual, institution and community difference which plays a crucial role in determining how high or low a risk is and it acceptability . and also about the bioram application which is a computerized risk assessment tool.
Lastly,I learnt about the difference between not"Risk Adverse " & "Risk Tolerance," likelihood adverse "& consequence Adverse" and their graphical representation.
Thank you so much prof . IYA EZE for the organization of the video lesson. God bless you MA'AM.
In summary, regarding Biorisk characterization and evaluation it involves assessing the potential risks associated with biological agents or materials. This process includes identifying evaluating the likelihood of exposure, and determining the consequences of such exposure. Key points in biorisk characterization include understanding the nature of the biological agent, its pathogenicity, and the routes of transmission. Evaluation involves assessing the impact on human health, the environment, and biosecurity measures. Notable findings may include the identification of high-risk areas, vulnerable populations, and potential mitigation strategies to reduce biorisk... Overall, biorisk characterization and evaluation are essential components of biosafety and biosecurity measures to prevent the spread of infectious diseases and protect public health.
Thank you ma for all your effort to ensure that we come out with excellent grades.

Thank you so much ma for this knowledge
Thank you so much ma for this online lecture.
I was able to understand most things about bio safety risk assessment as an analytical procedure design to characterize safety in the laboratory..
I also understood the reason why we should carry out biological risk assessment, the reason is because it allows a facility, laboratory or other operations to determine the relative level of the risk, it's different activities pose, and help good risk mitigation decisions so that the are targeted to the most important risk.
I was able to know the factor that affects biosafety which includes;
1) method of waste disposal
2) virulence
3) duration of exposure.
IN RISK CHARACTERIZATION
The first and second steps in the identification of hazard and threat based upon the situation;
1) A hazard is something with the potential to cause harm.
2) A threat is someone with intent to cause harm.
This means that "hazard" is used in the biosafety context while "threat" is used in the biosecurity.
The next step in the risk assessment is the characterisations of the hazard and threat based on the likelihood and consequences.
1) For hazard, consider the likelihood of the hazard to cause harm and the extent of the harm.
2) For the threat, consider the likelihood of the threat to successfully achieve their goals and the consequences of that goal.
Thank you once again ma for this impactful lecture.
May God grant you wisdom to impact on us..

BIORISK CHARACTERIZATION
This helps to evaluate route exposure .
Characterization and biorisk evaluation modifies pathogens, toxins and genetic materials
I have also learnt that risk assessment Is characterized by
Biosafety risk assessment
Biosecurity risk assessment.....
In conclusion, there's no systematic way if determining risk acceptability,
This will depend on the perception of individuals
Thanks for the informative lecture.
I learnt that Bio risk characterization is important in evaluating the communicability of biological hazards and helps in accessing, tracing, identifying and prioritizing bio risks. Also, bio risk evaluation and characterization helps in modifying toxins and pathogens, all aimed at safety in the Laboratory. And the process of characterizing these risks is called risk assessment which also has strategies and approaches to it.
I also understood that BioRAM (Biosafety and Biosecurity RAM) is a computerized risk assessment tool which was developed by Sandia National Laboratory in partnership with International Community. Bio RAM helps in determining relative risk levels.
In conclusion, accepting that there are such dangerous risk in the laboratory is the first step towards ensuring safety in the laboratory
Thank you very much ma for this lecture
I understood that a biological risk assessment is an analytical procedure designed to characterize biological risks in a facility, laboratory or unit within it, or other type of operation dealing with potential pathogens or toxins
A biosafety risk assessment is an analytical procedure designed to characterize security risks in a laboratory
A biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory
Reasons why we need a biological risk assessment:
A biological risk assessment allows a facility, laboratory, or other operation to determine the relative level of risk it’s different activities pose
I have learned and understand that risk characterization is the process of determining the likelihood and consequences of a particular risk with a risk assessment.
While risk evaluation I'd determining whether a risk is high or low, whether it is acceptable or not which can lead to implementation of risk mitigation measures.
I learned about a BioRAM which is a computerized risk assessment tool used to facilitate biosafety/biosecurity risk assessment by simplifying risk risk characterization.
Thank you very much for an amazing lecture
Here's brief summary of what ive learnt...
I learned thst Biological risk assessment is an analytical procedure designed to characterize biological risks in a facility, laboratory or unit within it or other types of operation dealing with potential pathogens or toxins.
Biological risk assessment is categorized info Biosafety risk assessment and Biosecurity risk assessment.
Biological materials are one of the highest levels of risks.
We need biological risk assessment cause it allows a facility, laboratory or other operation to determine the relative level of risks, it helps guide risk mitigation decisions so that these are targeted to the most important risks.
In summary,the risk tolerance curves shows different levels of risks from very low to very high.
Thank you ma once again.
Thank you Ma for the enlightening lecture.
I learnt about the meaning of Biological risk Assessment, The need for Bio-risk assessment, Factors to consider during Bio-safety and Bio-security Risk Assessment, The Steps involved in Risk Assessment, The BioRAM Tool and lastly Risk Evaluation and it associated terms.
Biological Risk Assessment: is a procedure carried out to characterize biological risks in a laboratory. It cuts across that of biosafety and biosecurity risks.
Biosafety risk assessment is used to characterize safety risks while that of biosecurity is used to characterize security risks.
The need for a biological risk assessment is to allow a laboratory or facility know the risks associated with different activities (risk characterization) and helps in guiding mitigation decisions (risk evaluation).
Factors to consider during biosafety risk assessment are:
1. Method of waste disposal
2. Duration of exposure to the biological agents
3. Route of exposure
4. Laboratory Design
Factors to consider during biosecurity risk assessment are:
1. Location of the Laboratory.
2. Access Control
3. Accessibility
There are also factors that apply to both biosafety and biosecurity, they include:
Infrastructure/Equipment, Training/Staff competency and adherence to safety measures.
Biorisk Assessment involves two steps:
1. Bio-risk Characterization: This is the identification of hazards and threats based upon the situation.
Hazard is used in the biosafety context, while threat is used in that of biosecurity.
For a risk characterization to be termed as robust, it must have these qualities:
i. Comparability: the ability to trust the accuracy of the differences between assessments.
ii. Repeatability: rhe ability to conduct the same process on the same way for same hazard or threat.
In order to aid in risk assessment, the BioRAM which is a computerized tool helps to facilitate assessments by simplifying risk characterization.
2. Risk Evaluation: This is an intermediary step between risk characterization and taking active steps in mitigating the risk.
Noted is the fact that determining or evaluating risk do not involve a systematic way but depend on the perception of individuals, institutions and community.
To also communicate risk evaluation, the " risk tolerance curves" is used to show different levels of risks on a likelihood consequences graph of risk.
Terms associated with risk evaluation are:
Risk Adverse: When the graph of an institution shows more space for high risk, i.e they do not want any risk.
Risk Tolerant: When the graph of an institution shows more space for low risk, i.e they are ready to take chances.
Likelihood Adverse: When an institution focus more on the likelihood of a risk than the consequences.
Consequences Adverse: When an institution is more concerned about the consequences than the potential of an occurence.
Once again, Thank you Ma.
Thank u so much ma ❤ for this wonderful lecture.
Bio risk characterization and evaluation talks about the biological risk assessment, which is an analytical procedure designed to characterize biological risk in a facility, laboratory, or unit within it, or other type of operation dealing with potential pathogens or toxins.
Which has to do with:
Biosafety risk assessment
Biosecurity risk assessment
Biosafety risk assessment is the analytical procedure designed to characterize safety risks in a laboratory, while Biosecurity risk assessment is an analytical procedure designed to characterize security risks in a laboratory.
Why we need a biological risk assessment:
It is because it allows a facility, laboratory, or other operation to determine the relative level of risk its different activities pose and helps guide risk mitigation decisions so that these are targeted to the most important risks.
And evaluating the kind of risk we can be faced with using the likelihood and consequences and how fast we will act and the kind of protective equipment to be used.
The objective:
Biosafety and laboratory biosafety risk mitigation measures to reduce likelihood and consequences.
And also I learnt about hazards:
Hazard is something with the potential to cause harm, while threat is someone with an intent to cause harm.
And how risk are characterized into rubust, comparative and repeatability using the BioRam tool the evaluation of risk in their different understanding, thanks ma.
Thankyou ma for the lecture
I learnt that,
Bio risk management is basically a process systematically put in place before effective control safety and biorisk, it’s the likelihood of undesirable events that involves hazard, threat and consequences.
_The use of personal protective equipment can lower the likelihood of exposure.
_The use of physical barriers can lower the likelihood of theft.
The process of bio risk characterization must be Robust, Comparable and Reputable.
Components of bio risk management
-Assessment
-Mitigation
-performance.
Thank you so much ma for the wonderful lecture.
I learnt that biorisk assessment is an analytical procedure made or designed to characterise biological risks in a faculty, unit ir laboratory within it.
Risk assessment is a procedure or process that characterizes a particular situation in order to determine the likelihood and consequences of a certain adverse event and support decision making regarding the acceptability of the risk.
Risk characterization is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment.
Biosafety Risk Assessment is an analytical procedure designed to characterize safety risks in a laboratory.
Biosecurity risk is assessment is an analytical procedure designed to characterize security risks in a laboratory.
I also learnt that hazard are things with the potential to cause harm while threats is someone with the intention to cause harm.
The breakdown of bio risk characterization and evaluation was very helpful.
Risk characterization is the actual process of determining the consequences and likelihood of a particular risk occuring.. Two steps of risk characterization:
1.) Identification of hazard
2.) characterization of the hazard
Risk evaluation is the intermediate step between risk characterization and mitigation.
A relative risk is the value of one particular risk in terms of likelihood in the context of another risk.
In summary the Amp model is vital in the execution of bio risk management.
Thank you very much, Ma. Your lecture was incredibly informative.
I learned that: A risk assessment is a process that characterizes a particular situation in order to determine the likelihood and consequences of a certain adverse event (Risk Characterization) and supports decision making regarding the acceptability of the risk (Risk Evaluation).
A biosafety risk assessment is an analytical procedure designed to characterize safety risks in a laboratory. While a biosecurity risk assessment is a procedure that is designed to characterize security risks in a laboratory.
Risk is a function of both the likelihood of something happening and consequences of that occurrence.
Some of the factors that could affect biorisk assessment include:
* Training/Staff competency
* Infrastructure/Equipment
* Adherence to supply measures
Steps in risk assessment are:
* Identification of hazards and threats based on the situation.
* Characterization of the hazards and threats based upon the likelihood and consequences.
* The concept of relative risk.
Understanding the relative risk associated with different situations or by implementing different risk mitigation strategies is important for the overall process of risk characterization.
Risk Evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risk. It is highly related to the concept of risk acceptance.
Individual, Institution, and community factors might drive differences in risk acceptability.
Thank you ma for this lesson
Below are the few things I've learnt from this lesson ma
Biological risk management is an analytical procedure designed to characterise biological risks in a facility, laboratory or unit with it or other types of operations dealing with potential pathogens or toxins.
Biological risk management are two types; the BIOSAFETY RISK ASSESSMENT; which is an analytical procedure designed to characterise safety risk in a laboratory. And BIOSECURITY RISK ASSESSMENT; which is an analytical procedure designed to characterise security risks in a laboratory.
Why we need biorisk assessment is because it allows a facility, laboratory or other operation to determine the relative level of risk,it different activities pose and helps guide risk mitigation decisions so that these are targeted to the most important risk.
A risk assessment assigns values for likelihood and consequences,which allows to represent the risk of a particular adverse event on a graph.
The objective of risk assessment is to support the selection of appropriate laboratory Biosafety and laboratory Biosafety risk mitigation measures to reduce likelihood and consequences of injury, sickness or breaking into the lab to take those highly risk pathogens.
The biosafety factors includes; method of waste disposal, duration of exposure,lab design, route of exposure, virulence.
Biosecurity factors are; motive of the person, security of the agent, accessibility, location of lab,access control and opportunity.
Also,Risk characterisation is the actual process of determining the likelihood and consequences of a particular risk assessment.
We can only determine the likelihood of consequences of a very well defined risk.
Also, characterising the material allows one to determine important parameters for likelihood and consequences such as route of exposure, infectious dose, incubation time, mortality,communicability and others.
For biosecurity risks,the threat is an adversary, aiming to acquire the biological materials (hazard) and use it to cause harm.
A hazard or threat cannot itself pose a risk without a specific situation. A situation also does not represent a risk without a hazard or threat. Both a changing hazard or threat and a changing situation will independently alter the scenerio being assessed and thus change the risk.
Relative risk is the value of one particular risk (in terms of likelihood a d consequences)in the context of another risk.
It is important that risk characterisation process should be as robust as possible.
Comparability is the ability to trust the accuracy of differences between assessments,due to similarities in their bases, assumption, procedures and protocols.
Repeatability is the ability to conduct the same process in the same way for the same hazard or threat and situation over a period if time or for different hazards,threats and situations at the same time.
Robust risk characterisation process will generate similar results when assessing similar hazards or threats in similar situations,no matter who is following the methodology.
A robust risk characterisation makes a risk assessment robust.
BioRAM is the available tool to aid if laboratory risk assessment is biosafety and security RAM.
Risk evaluation is a crucial intermediary step between risk characterisation and taking active steps towards mitigating risk.
The factors that might drive differences in risk acceptability between individuals, institutions and communities are;
Individual factor; which are personal preference,beliefs system, reputation and funding
Institutional factors; which are reputation,legal issues, funding, infrastructure, management, commitment, policies,rules and regulations.
Community factors; which includes community awareness,Norms and values and belief systems, culture, educational advancement, benefits, political and community interest.
And finally, consequence averse is when an institution os only worried about the consequences regardless of the potential for an occurrence
Biorisk Characterization helps us to evaluate infectious diseases, incubation time and route exposure.
I also understand, how to identify and characterised those risks that are rising in the laboratory.
I also understand that Biorisks evaluation and characterization is the processing of assessing the potential risk associated with biological agent and it also modified pathogen, genetic material and toxins and expose biological agent that cause gems.
Bio Ram: It is a computerized risks assessment tool developed for laboratory safety and bio security risks assessment.
Thank you ma for this wonderful lecture
Thank you very much for your insightful and informative lecture on BIORISK CHARACTERIZATION AND EVALUATION.
To summarize, a biological risk assessment is a systematic process that aims to identify and evaluate risks associated with potential pathogens or toxins within a facility or laboratory. Conversely, biosafety risk assessment focuses on safety risks within a laboratory setting, while biosecurity risk assessment targets security risks.
Understanding the importance of conducting a biological risk assessment is crucial. It allows facilities and laboratories to assess the level of risk posed by their activities and make informed decisions to effectively mitigate these risks. Risk, in this context, refers to the likelihood of an undesirable event occurring, which involves specific hazards and potential consequences.
Risk assessment involves analyzing a situation to determine the probability and potential impact of adverse events. Assigning values for likelihood and consequences enables us to visualize the risk on a graph and prioritize risk management strategies accordingly.
Factors influencing biosafety include methods of waste disposal, exposure duration, pathogen virulence, laboratory design, and routes of exposure. Similarly, biosecurity is influenced by motives, laboratory location, agent security, access control, and opportunities for breaches.
Risk characterization involves assessing the likelihood and consequences of identified risks within a risk assessment framework. Comparability ensures accuracy in evaluating differences among various risk assessments, while repeatability focuses on the consistency and reliability of conducting risk assessments over time and across different hazards and scenarios.
Lastly, BioRAM, developed by Sandia National Laboratories in collaboration with the international community, is a computerized tool designed to facilitate laboratory risk assessments.
Thank you ma'am,
In this lecture I learnt that bio risk mitigation are actions and control measures that are put in place to reduce the risk associated with biological toxins and agents .
There are five basic mitigation control methods which are:
1. Administrative control : These are policies that result in providing proper guidance for safety
2. Engineering control: it has to do with the physical change in the environment that reduces or prevent hazard this method is most effective but costly measure it requires regular maintenance
3. Elimination and substitution : elimination involves the removal of hazards from biological agents completely while substitution involves replacing a hazardous substance or process with a safer alternative
4. Practices and procedures
5. Personal protective measures: This simply involves the provision of individual protective equipment such as gloves, respirators etc. This is the least preferred method because it depends only on the individual usage of the equipment however the most level method will depend on the type of risk
Bio risk characterization plays a crucial role in assessing various aspects of exposure to biological agents, including routes of exposure, communicability, incubation periods, and the potential for infectious diseases. Through this process, I have gained insights into how to identify and evaluate emerging risks within laboratory settings.
Additionally, I learned that bio risk evaluation and characterization involve the analysis of modified pathogens, toxins, and genetic materials, as well as identifying biological agents that may pose risks, such as pathogens that can spread germs.
Several factors contribute to the differing capabilities of individuals and communities in managing these risks:
1. Community Awareness:The level of knowledge, norms, and values within a community significantly influences its ability to respond to bio risks.
2. Individual Beliefs: Personal reputation and belief systems can affect how individuals perceive and react to risk.
3. Institutional Frameworks: Institutional rules, legal regulations, and policies play a vital role in establishing safety protocols.
Moreover, there are computerized risk assessment tools specifically designed for evaluating laboratory safety and biosecurity, enhancing our ability to identify and mitigate potential threats effectively.
Thank you ma for yet another wonderful lecture on Biorisk Characterization and evaluation .
At the end of this lecture I was able to understand the process of identifying and describing the biological agent, its properties, and its potential risks.
What is Bio risk assessment?
Bio risk assessment is the process of assessing the likelihood and potential impact of a biological agent causing harm.
Biosafety risk assessment:
Bio safety risk assessment characterizes safety risks in the laboratory. It also determines the level of risks that can be caused by different activities.
Biosecurity risk assessment: is an analytical procedure that is designed to characterize security risk in a laboratory.
Why do we need it?
- it allows the facility,laboratory or other operations to determine the relative level of risk and helps guide risk mitigation.
What is Bio mitigation: They are those actions or control measures that are put into place to reduce or eliminate the risks associated with biological agents and toxins.
Biorisk characterization: this determines the likelihood and consequences of a particular risk. Biorisk characterization helps us to evaluate route, exposure, incubation time and infection disease.
Bio risk evaluation modifies pathogens,toxins and genetics materials.
Steps in Biorisk Evaluation_:
1. Hazard Identification_: Identify the biological agent and its potential hazards.
2. Risk Assessment: Assess the likelihood and potential impact of the biological agent causing harm.
3. Risk Characterization_: Describe the risk in terms of its likelihood and potential impact.
4. Risk Mitigation_: Identify and implement controls to mitigate the risk.
Factors to Consider in Biorisk Evaluation
1. Agent Characteristics_: The biological agent's properties, such as its:
- Virulence
- Transmissibility
- Stability
- Reactivity
2. _Exposure Pathways_: The ways in which individuals may be exposed to the biological agent, including:
- Inhalation
- Ingestion
- Skin contact
- Mucous membrane contact
3. _Vulnerable Populations_: Individuals who may be more susceptible to the biological agent's effects, including:
- Immunocompromised individuals
- Pregnant women
- Children
- Elderly individuals
4. _Environmental Factors_: Environmental conditions that may affect the biological agent's survival and transmission, including:
- Temperature
- Humidity
- Lighting
- Ventilation
Risk Assessment Methodologies
1. _Qualitative Risk Assessment_: A subjective approach that uses expert judgment to assess the risk.
2. _Quantitative Risk Assessment_: An objective approach that uses numerical data to assess the risk.
3. _Semi-Quantitative Risk Assessment_: A combination of qualitative and quantitative approaches.
Benefits of Biorisk Characterization and Evaluation
1. _Informed Decision-Making_: Biorisk characterization and evaluation provide valuable information for decision-making.
2. _Risk Mitigation_: Identifying and evaluating bio risks enables the implementation of effective risk mitigation measures.
3. _Compliance with Regulations_: Biorisk characterization and evaluation help ensure compliance with relevant regulations and guidelines.
Thank you ma.
Thank you ma.. in summary i learnt that biorisk assessment is an analytical procedure designed to characterized safety risk in a laboratory while risk assessment is a process that characterize a particular situation in order to determine the likelihood and consequences of a certain adverse event .Risk evaluation is also taking steps towards mitigating risk..
BIO RISK CHARACTERIZATION
Thank you so much ma I really understand a lot
I understood that bio risk characterization and evolution involves the process of biosafety assessment, which is also the measure taken to identify an characterize those risks that are rising in the laboratory, which is as a result of working with biochemical specimens and also from handling laboratory equipments.
Physical risks involved in the laboratory that deals with biochemical samples as a whole. It also identifies hazards that threats base on the specific situation and one of the important tools that facilitate the assessment of laboratory risks is the BIO RAM.
Thank you ma for this teaching.
In summary, I've learnt that Bio risk allows a medical laboratory scientist to determine the relative level of risk and different activities pose and helps guide risk mitigation decisions and also got to know the difference between biosafety and biosecurity factors and I learnt that characterization and evaluation helps to identify and access specific biorisk which will further aid to prefer the right mitigation measures.
Lastly I learnt the different risk and hazards associated experiments that take place in the laboratory and one of the ways of avoiding this risks
Thank you dr Iya Eze Bassey for this simplified lecture.
Through this lecture i have learnt that bio risk characterization is the actual process of determining the likelihood and consequences of a particular risk within a risk assessment and the first step in risk assessment is the identification of ;
1. Hazards
2. Threats based upon the situation
Risk evaluation is a crucial intermediary step between risk characterization and taking active steps towards mitigating risk.
It is hugely related to the concept of risk acceptance.
Also through this lecture I got to understand that in characterizing risk under biosafety you have to adhere to this ;
- The use of PPE can lower the likelihood of exposure
- Vaccines can lower the consequences of exposure
While under biosafety
- The use of physical barriers aids in lowering the likelihood of theft.
- The availability of therapeutics can lower the consequences of malicious release
* It is also important to note that precise location of the risk tolerance curve on the graph is fact arbitrary and it's the essence of risk evaluation.
Thank you for the wonderful lecture
Here is the summary;
Biorisk characterization is the actual process of determining the likelihood and consequences of a particular adverse event....
*Steps for biorisk characterization*
Step1: identification ofa hazard and threat based upon the situation
Step2: characterization of hazard and threat based upon the likelihood and consequences.
Step3:decide whether its acceptable or not.if yes;proceed with your work and monitor
If no;close down the project....prepare a risk control action plan, implement and then review the plan
For hazard,consider the likelihood of the hazard to cause harm and the extent of the harm (biosafety risk)
For threat consider the likelihood of the threat to successfully achieve their goal and the consequences of the goal.
*Biosafety risk characterization*
The hazard is the biological material worked with in the lab.
Characterization of material allows one to determine important parameters for likelihood and consequences such as route of exposure, infectious dose, incubation time, mobility, mortality, communicability and others.
*Biosecurity risk characterization*
For biosecurity risk,the threat is adversary aiming to acquire the biological materials and use it to cause harm.characterising potential adversaries allows one to determine important parameters for likelihood and consequences such as means,motives and opportunity.
A hazard or threat cannot itself pose a risk without a specific situation and neither does a situation.both a changing hazard or threat and changing situation can alter the scenario being asssessed and this changes the risk.
The hazard or threat can affect both the likelihood and consequences of a risk,the situation will only affect the likelihood and the consequences will remain the same because the agent will not change.....
*Relative risk*
is the value of one particular risk(in terms of likelihood and consequences)in the context of another risk.
It is important that your risk characterisation is as robust as possible
It will generate similar results when assessing similar hazards or threats in similar situations no matter who is following the methodology where the characterization is being conducted and when its occuring.
BIORAM;is a computerised risk assessment tool developed by Sandia laboratories in partnership with international communities to facilitate laboratory biosafety and security risk assessment by simplifying risk characterisation.its uses only one of several possible risk assessment methodologies.it helps to determine the relative risk levels in a comparable and repeatable way.
* RISK EVALUATION*
Are crucial intermediary steps between risk characterisation and taking active steps towards mitigation risk.it helps to determine whether a risk is high or low and whether it is acceptable to proceed with or not (leading to implementation of risk mitigation)
Different institutions have different opinions for what is high or low or even what shapes of the curves are. Risk evaluation drives investment decisions in an institution particularly risk averse,it will spend more time in reducing the risk. It proceeds with procedures even if others think it dangerous...(I.e likelihood averse)
Consequences averse: an institution is worried about the consequences regardless of the potential for an occurrence.
Once again..thank you ma for the lecture
Thank you ma for this well explained lecture. I really got value.
I learnt about Risk Assessment as it tends to affect biosafety *Hazards-* biological materials that causes harm and biosecurity *Threat-* someone with an intention to cause harm.
Biological risk assessment has to do with the process of evaluating the potential risk associated with biological agents. It entails hazard identification, risk assessment, risk characterization and risk management. It comprises Biosafety risk assessment and Biosecurity risk assessment.
I discovered the factors that affect Biorisk assessment and they are: Waste disposal methods, virulence, route of exposure, motive, accessibility, access control etc.
Furthermore, I realised that Biorisk characterization is the process of determining the likelihood and consequences of a particular, well defined risk within a risk assessment. This process must be robust, comparable and repeatable.
Moreover, there are some steps to take in the Risk assessment;
• Identify the hazards and threats based on the situation.
• Understand the concept of Relative risk.
• Characterize the hazards and threats bases on likelihood and consequences.
I got to understand that *Hazard* is something (biological material) with the potential to cause harm while *Threat* is someone with the intent to cause harm. This brings about the Biorisk blackmailing.
Lastly, the 'Risk likelihood Averse' and 'Risk consequence Averse' graphs disclosed the different risk tolerance levels.
Thank you ma for the wonderful lecture
I learnt that;
1. Bio risk management is basically a process
2. The use of personal protective equipment can lower the likelihood of exposure.
3. Bio risk management is basically the process systematically put in place before effective control safety and bio risk
4. Bio risk is the likelihood of undesirable events that involves hazards, threats, and consequences
5. The use of physical barriers can lower the likelihood of theft.
The process of Bio risk characterization must be ROBUST, COMPARABLE, AND REPUTABLE.
From the wonderful lecture i waa able to deduce that
Biorisk evaluation and characterizations is an analytical procedure designed to characterise biological risks in a facility, laboratory or unit within it or other type of operation dealing with potential pathogens or toxins
A biosafety risk assessment is an analytical procedure designed to characterise safety risks in laboratory
We need biological risk assessment because it allows facilities,labs or other operations to determine the relative levels of risk activities pose and help guide risk mitigation decisions
Thank you ma for the well explianed lecture
I learnt that biological risk assessment is an analytical procedure designed to charactrize biological risk in a facility,laboratory or unit within it,or other type of operation dealings with potential pathogens or toxins
It consists of
(1) Biosafety risk assessment - is an analytical procedure designed to characterize security risk in a laboratory.
(2) Biosecurity risk assessment-allows a facility, laboratory or other operation to determine the relative level of risk its different activities pose and helps guide risk mitigation decisions so that these are targeted to the most important risk
Risk is the likelihood of an undersirable event happening, that involves a specific harzard or threat and has consequences.
Bio Ram- Biosecurity and Biosafety is computerized risk management
Tool developed for laboratory safety and bio risk assessment
Thank you so much ma for this wonderful lesson on
"Bio Risk Characterization and Evaluation",
I understand a systematic process to:
1. *Identify*: Recognize potential biological hazards (e.g., pathogens, genetically modified organisms, biological waste)
2. *Characterize*: Determine the intrinsic properties and characteristics of the biological hazard (e.g., virulence, transmissibility, stability)
3. *Assess*: Evaluate the likelihood and potential impact of exposure to the biological hazard
4. *Evaluate*: Compare the bio risk to established standards, guidelines, and criteria to determine the level of risk
This process involves:
1. *Hazard identification*: Identify potential biological hazards
2. *Risk assessment*: Evaluate the likelihood and potential impact of exposure
3. *Risk characterization*: Determine the severity and probability of adverse effects
4. *Risk evaluation*: Compare risks to established standards and criteria
The goals of bio risk characterization and evaluation are to:
1. *Determine the level of risk*: Assess the likelihood and potential impact of exposure
2. *Inform risk management decisions*: Provide data-driven insights to guide bio risk mitigation strategies
3. *Prioritize resources*: Allocate resources effectively to manage bio risks
4. *Ensure compliance*: Meet regulatory requirements and guidelines
By characterizing and evaluating bio risks, organizations can develop effective risk management strategies to mitigate potential biological hazards and ensure a safe working environment.
Thank you Ma for the wonderful teaching. I have learnt so much for this episode Like ......
Bio-risk characterization and evaluation are essential steps in bio-risk management!
Bio-risk characterization involves:
1. *Identifying* potential biological hazards (e.g., infectious agents, toxins, genetically modified organisms).
2. *Assessing* the likelihood and potential impact of an adverse event (e.g., exposure, infection, environmental release).
3. *Describing* the characteristics of the biological material (e.g., virulence, transmissibility, stability).
Bio-risk evaluation involves:
1. *Analyzing* the information gathered during characterization.
2. *Determining* the level of risk associated with the biological material (e.g., low, moderate, high).
3. *Categorizing* the risk based on established guidelines (e.g., WHO, CDC, NIH).
The goals of bio-risk characterization and evaluation are to:
1. *Understand* the potential risks associated with biological materials.
2. *Inform* decisions about handling, storage, and use.
3. *Develop* effective risk mitigation strategies.
By conducting thorough bio-risk characterization and evaluation, laboratories, organizations, and individuals can minimize the risks associated with biological materials and ensure a safe working environment
Thank you very much ma for this wonderdul lecture
I have learned alot ..
Firstly what is Risk
Risk is the likelihood of all undesireable event happening that involves a specific hazard or threat and has consequences..
I also learnt that biorisk assesment is an analytical procedure designed to classify biological riak ina facility ,laboratory,or a unit within it..
Biorisk assesment is divided into 2 namely..
1, biosafety risk management
2, Biosecurity risk management
Also biorisk characterization helps to evaluate route exposure,communicability,incubation time,and infection disease.
Biological risk assesment is also important because it allows a facility ,laboratory or other operation to determine the relative level of risks its different activities poses, and helps to guide in risk mitigation decision..
Lastly Bioram::::::;Biosecurity and Biosafety is a computerised risk assesment tool developed for laboratory safety and bio security risk assesment...
Thank you very much maam ❤
Thank you very much ma for this interesting lecture I was able to understand that biological risk assessment is an analytical procedure designed to characterize biological risk in a facility, laboratory or unit within the potential pathogens or toxins.
Risk is the likelihood of an undesirable event happening that involves a specific hazard or threat and has consequences. the first step in risk characterization is the identification of hazard and threat based upon the situation
A hazard is something with the potential to cause harm.
A threat is someone with the intent to cause harm
Risk evaluation is a crucial step between risk characterization and taking active step towards mitigation risk.
Thank you Ma for this enlightened lecture, I appreciate your effort.
After watching the video, I came to an understanding that;
Biorisk characterization help us to evaluate route exposure, communicability, incubation time and infection disease.
Biorisk assessment is very important as it allows a facility or operations to determine the likelihood of undesirable events, the level of the repercussions associated with the risk as well as helping to guide mitigation decision.
Factors that drive different in capabilities between individuals and community are;
1. Individual factors
Reputation and believe system
2. Community factors
Awareness, norms and values
3. Institution factors
Rules, legal issues, policies
BIORAM
Biosecurity and biosafety is a computerised risk assessment tool developed for laboratory safety and bio security risk assessment.
In summary,
The AMP model is vital in the execution of Biorisk Management.
A: The Biorisk assessment is divided into Biosafety and Biosecurity assessments. Biorisk Assessment is important because it helps one to have an idea of the gravity of the risk posed by agents in an environment.
Risk is majorly influenced by two factors namely; Likelihood and Consequences.
The biosafety factors and the Biosecurity factors are used in Biorisk Assessment.
In risk assessment, the identification of hazards and threats is pertinent.
Your accurate delivery of these topics in a concise manner is applaudable.
Thanks you ma for this lecture
I learnt the risk of working in a laboratory.
Risk which is the likelihood of an undesirable event happening that involved a specific hazard or threat and has consequences.
Measures taken for biosafety including engineering control,personal protective equipment and for biosecurity which include doors with locks, password/ pin.
The biorisk management model which compose of biorisk assessment,biorisk mitigation and biorisk performance. You discussed on biorisk assessment were you talked about it's characterization and evaluation, and how biorisk assessment is designed to characterize biological risks in a facility, laboratory or unit within it, we have two risk assessment taken biosafety risk assessment( hazards - something with the potential to cause harm) and biosecurity (threats- someone with intent to cause harm) . They are stepd taken to characterize the risk which are identifying your hazards and threats based on the situation then characterize the likelihood and consequences of the hazard and threat. A hazard or threat cannot itself pose a risk without a specific situation, and also wen characterizing biosafety and biosecurity risk the use of PPE and physical barrier can lower the likelihood of exposure and theft while vaccines and therapeutics can lower the consequences of exposure and theft respectively.
Risk evaluation which is the process of determining subjectively whether a risk is high or low and whether it's acceptable or not( leading to implementation of risk mitigation measures, some factors that drives the difference in risk acceptability between institutions, communities are individuals factors ( personal preference), institution factors ( reputation, policies, rules and regulations) and community factors ( belief system, norms and values, culture) .difference between a risk averse and risk tolerance is that risk averse will spend more resources on attempting to reduce the risk it faces while risk tolerant might proceed with procedures others might find too dangerous thank you ma
Thank you ma for the impactful and self explanatory lecture. For the summary:
Biorisk characterisation and evaluation are essential aspect in laboratory and facilities the deal with pathogens and toxins.
Biorisk characterisation is a process to determine the likelihood an consequences of a particular risk within a risk assessment.
The risk assessment help us to determine the biological risk in a laboratory.
In characterizing risk assessment we have Biosafety Risk assessment (procedure design to characterize safety risk in the lab) and
Biosecurity risk(procedure design to characterize security in the lab).
They are 3 major step in Risk Assessment 1 identification of the hazard and threat
2 Characterizing the hazard and threat
3 the concept of relative risk
These 3 major steps help in risk assessment.
Risk Evaluation help you to determine if a risk is low/high, Acceptable and what can be done to mitigate it
Thanks for this great impact ma.
Bio-risk assessment is the process of identifying the hazards and evaluating the risk associated with biological agents and toxins, taking into accounts the adequacy of any existing controls and deciding whether or not the risks are acceptable, bio-risk characterization is the process of determining the likelihood and consequences of a particular, well defined risk within a risk assessment.also there are certain parameters for likelihood and consequences of which bio-risk characterization helps to determine. They are as follows; Route of exposure, infectious dose, incubation time, morbidity, communicability, etc....
The difference between hazard and threat is that a hazard is something that has the potential to cause harm whereas threat is something that has an intention of causing harm.
STEPS IN RISK ASSESSMENT
1. Identify the hazards and threats based on the situation.
2. Understand the concept of relative risk.
3. Characterize the hazards and threats based on likelihood and consequences.
A biological risk assessment allows a facility or laboratory to determine the level of risks and help guide risks mitigation decisions so they are targeted to the most important risk.
Once again thank you for breaking down this topic for me ma.
Thank you ma for this wonderful lectures

REPEATABILITY:Is the ability to conduct the same process in the same way for the same hazard or threat and situation over a period of time or for different hazard ,threat and situations at the same time..
And finally,BioRAM is a computerized risk assessment tools developed by (SANDIA NATIONAL LABORATORIES)in partnership with the international community to facilitate laboratory biosafety and dis- security risk.
RISK EVALUATION; Is a crucial intermediary step between risk characterization and taking active steps towards mitigating risk...
Thanks once again Dr. Iya Eze Bassey for your enlightenment and educating section...
Once again thank you so much man for the wonderful lecture.
In summary: Biorisk characterization is the process of determining the likelihood and consequences of a particular, well defined risk within a risk assessment.
Then also in the lesson it also showed that there are certain parameters for likelihood and consequences of biorisk characterization which helps to determine
Which are: Route exposure, communicability, incubation time, infectious Dose, morbidity.
Also learnt that biorisk characterization and evolution are involves in the process of biosafety assessments.it is also the measure that is taken to identify an characterize those risk that are rising in the laboratory, in that case is a result of working with biochemical specimens and also from handling laboratory equipment. 0:37
Thank you very much ma for the great lecture
Bio risk assesment is an analytical procedure designed to characterize biological risk in a laboratory ,facility or unit .
In other words it is an anlytical procedure designed to characterize security risk in a laboratory.
Why do we need bio risk assessment
..it allows facility or laboratory to determine the relative level of risk
...it helps guide risk mitiation
Risk is said to be the likelihood of undesirable occurence that leads to death,injury or damage
Bio risk characterization and evaluation involves assessing the potential risk associated with biological agents or materials.
This.process involves indentifying hazards ,evaluating the likelihood of exposure and determining the consequences of such exposure
Evaluating means accessing the kmpact on health,the enviroment and biosecurity measures
