Thanks...really informative and easy to understand the changes...
i would like to find an explanation of when HV gloves are required especially when working near high voltages -- class 4 gloves go up to 36kV, workers often assume you need gloves to meet the voltage being "worked" on. example operating 230kV manual switch. what gloves are required? the worker is only indirectly working on 230kV - operating a switch handle. another example would be testing voltage or applying grounds on 13.8kV circuits -- what gloves are required?
Hi , I like your lecture
Hey, thanks
Risk Assessments are fine and effective if and only if those performing it are genuinely trying to determine the hazards involved and the best way of eliminating or mitigating them. However in most cases, the vast majority of electrical workers just go through the motions and their assessment of risk is subjective as best. One guys thinks working on energized 120 volts is safe because he's using insulated tools while a different worker thinks his training, experience and technical skills will keep him safe. Very seldom if ever will such workers ever consider placing the equipment into an Electrically Safe Work Condition (ESWC) because it takes too long, isn't necessary for "only 120 volts" and "I've done it a hundred times and nothing has ever happened to me".
And this is where the employer, AKA managers and supervisors must perform audits of their employees to ensure they are not only following safety rules but are actively and effectively performing a risk hazard assessment using the priorities as listed in hierarchy of risk controls to determine if the hazards can be eliminated, i.e. placed into an ESWC as the first and foremost choice.
Thanks Jim
Do you have cal/cm2 for Metal Sheet based on material and thickness?

Great❤❤❤
I'm a registered PE and I've been asked if I could provide NFPA 70E training to our workforce. Who decides (state agency, federal agency) whether or not a person is qualified to provide this training and a Certificate of Completion? What is proper procedure to become certified to train?
That is a great question. There is no qualifying body for training. That means although there are some excellent trainers for NFPA 70E, the opposite is also true. On many occasions, I have conducted training at an organization only to hear someone say, wow, that is not what the last person said. Then I explain why things are they way they are having been involved with much of it along the way. They just shake their head saying the last person obviously didn’t do a good job.
The certificate is also another issue. Many will state “Qualified” in their title - referring to training for qualified workers but giving the impression that they qualify the worker. At best, there is a test and then a certificate of completion/passing the test but not actually “qualifying” a worker.
If you are going to teach NFPA 70E, read, learn, ask questions etc. Sometimes what you read on the internet may not be correct (where have we heard that before), I’ve seen this on a few occasions so check multiple sources too.
Good luck and best wishes for a successful training program. It is quite important in helping people avoid electrical hazards and the potentially terrible outcomes.
There is some additional information at my website www.brainfiller.com Check back if you have any other questions.
There seems to be an argument in our industry as to the qualifications of the individual performing an arc flash study. Does NFPA 70E mandate that you must be a licensed PE to do the study? Does OSHA require this? Another instructor told us that arc flash studies are clearly an engineering study and to perform such a study without a license is illegal in most states. Your thoughts?
Great question. I often hear of people attempting a study with limited knowledge of power system analysis etc.. Unlike other studies, if an arc flash study is incorrect, the results can affect a person's safety.
Years ago I was co-author of the first draft of IEEE 1584.1 The "dot one" standard is about specifying arc flash studies. The first draft mentioned qualifications including a P.E. We were asked to remove it. Instead, there is language referencing a person to check with the state licensing board to determine if a P.E. is required - which is frequently the case.
Many states also have an exemption if you are performing the study for your own company (not an engineering company performing work for others). So the final answer, is check the individual state's engineering licensing board.
Can anyone provide me 70E 2018 Edition PDF file?
Ibrahim Hossain You have to purchase it. Otherwise it is a copyright violation and is illegal. NFPA.org
Brainfiller Arc Flash Training no wonder they change it every 3 years...need to sell more standards.
