- The objectives for this module are that, by the end, learners should be able to (1) describe the agencies and organizations that regulate occupational health and safety, (2) locate regulations and guidelines relevant to a particular workplace hazard, and (3) apply occupational exposure limits to assess exposure risks.
This lecture is highly appreciable. Thank you so much sir.
good work prof
Hi, this was fantastic. ACGIH is not a consensus group, and TLVs and BEIs are not consensus standards.
Professor Peters: Thank you for your obvious investment of time and expertise....very much appreciated!
I need your additional help to understand "non-traditional" (10-12hr sampling).
My assumption is that after adjusting the OEL (PEL, TLV), via the Brief & Scala or the OSHA formula; one would simply modify the 8-hr TWA formula, substituting a 10hr or 600 minute sampling period with assumptions (as described: zero exposure; average exposure; worst case exposure) for non-sampled periods. Am I correct in my understanding? ...if not...could you please clarify? Also...considering that NIOSH REL's are based on a 10-hr work shift...am I correct in concluding that when applying a REL to a 10-hr shift; no adjustment is necessary. But...if sampling a standard 8-hr shift, the REL (10-hr) must be adjusted "downward" from 10-hr to 8-hr.
Thank you in advance for your time to reply.
Respectfully,

Glad you liked the video. You are correct in your understanding. Also, no adjustment would be needed for NIOSH REL's. I looked for information on adjusting downward and could not find anything. I recommend not adjusting the REL downward for a shorter time.
Exposures are typically log-normally distributed, which means that sometimes various workplace and production factors come together to produce a small number of high exposures. Thus, I recommend taking action if exposures commonly exceed ~10% of the OEL.
