Chemical Process Safety (PSM/RMP)

On December 14, 2023, OSHA published its revised Compliance Directive for Process Safety Management standard 1910.119, effective January 26, 2024. This new version is in Q7A format and was done nicely, although there are a number of things in the answers that I am sure will be challenged.  I have highlighted some of the interesting…...

Sweating the “small stuff” matters in process safety management.  Meeting the details of our chosen RAGAGEPs matters!  Although I am often told, “That is a picky audit finding,” it is what it is.  Far too many facilities believe that designing their process piping to be bolted flange assembly vs. welded joints is somehow easier; in…...

We have discussed the critical role of “torque” in constructing our chemical processes.  I catch a lot of flack for my insistence on this critical function, for which I am genuinely surprised.  But our piping design and construction RAGAGEP (ASME B31.3) is pretty clear on the matter, and now OSHA and EPA have “caught on”…...

Another pressuring test “gone bad”.  I want to remind anyone who wonders how to DEFINE and QUANTIFY a “safe distance” when piping is being pressure tested, especially when that test is a “pneumatic” test.  ASME PCC-2–2022, Repair of Pressure Equipment and Piping, Mandatory Appendix, 501-III, Safe Distance Calculations for Pneumatic Pressure Test is an EXCELLENT resource to…...

Over the next 2.5 hours, the entire 178,400-pound chlorine load was released,…...

I think most businesses are familiar with “backup power” sources, from battery packs on exit signs and egress lighting to UPSs on servers for their IT needs. But for facilities that store, handle, and process hazardous materials AND with safety systems associated with the storage, handling, and processing of those HAZMATs, there are some additional…...
