Under the International Fire Code (IFC), N-Methyl-2-pyrrolidone (NMP) is not classified as a “Toxic” or “Highly Toxic” material. While NMP is legally classified as a toxic substance under environmental and labor laws (such as the EPA’s TSCA and OSHA’s Hazard Communication Standard) due to its health effects, the IFC uses a very specific, narrow definition…...
I’m in Grand Rapids this week working with a client on a flammable liquids process that is under the PSM TQ, but over the Maximum Allowable Quantity for “outside”. The city began adopting the IFC in 2006 and is now using the 2021 edition. I am sharing the PPT file for the management presentation/training, if…...
The short answer is NO, but if we do, there’s a significant catch regarding its protection rating. Under OSHA standards (29 CFR 1910.134), you are technically allowed to perform a Qualitative Fit Test (QLFT) on a full-face respirator, but doing so limits its Assigned Protection Factor (APF) to 10. Here is the breakdown of why…...
The short answer is no. Radiographic Testing (RT) and pressure testing (Hydrostatic or Pneumatic) serve two (2) fundamentally different purposes in piping integrity. While it might seem like “over-testing,” they are not interchangeable in ASME B31.3 (Process Piping) or ASME B31.1 (Power Piping). Here is the breakdown of why 100% RT does not exempt you…...
Respondent owns and operates two (2) anhydrous ammonia distributing facilities. EPA Region 7 conducted inspections at the one (1) facility in August 2023 and at the other facility in December 2024 to determine compliance with Section 112(r) of the CAA and 40 C.F.R. Part 68. Information gathered during the EPA inspections revealed that Respondent hadcgreater…...

I was playing around with Google Gemini and wondered about its limitations and accuracy. One of the problems in my HAZMAT courses is showing just how small an amount of Cl2 it takes to achieve an IDLH concentration in a given space. So I asked it.. How many pounds of Chlorine Gas will it take…...
When I explain this to a group, I always get a challenge from some engineer that what I am saying is not accurate. And after all, they are the “engineers.” So today I asked Google Gemini to explain it to me… Q: Can a human hold up a wall that is 20′ long and 8’…...
We have a long-time client for whom we have now completed OSH and/or PSM/RMP audits at all of their North American facilities over the past 8 years. And this last audit was a “deal breaker” for many clients, as they were fit to be tied after the audit. Seems the facility had run its Safety/PS…...
I share this, as many may not recognize the power of a vacuum as a form of hazardous energy. ZERO = 0 and a vacuum is NOT zero, its actually LESS THAN ZERO! I added this video to the library this weekend. It demonstrates the power of a vacuum and why ALL energy sources MUST…...
