According to ASME PCC-2, Mandatory Appendix 501-III, determining safe distances for pressure testing—specifically,...

So I asked Google Gemni + to calculate the pressure wave in a room that is 40′ X 40′ X 20′ tall with a 5,000-gallon pressure vessel 85% full of liquid NH3, and it catastrophically fails. How much of a pressure wave will this event create in psig? I promise you this… No Engine Room I have ever been in could withstand this event! Google Gemini + equated it to TNT!

In section 2, element 2.5, of an RMP, facilities must report the quantity of toxic chemical that the facility used for the worst-case analysis. When reporting this data element in RMP*eSubmit for a mixture, should facilities report the entire weight of the toxic mixture potentially being released or only the amount of the regulated toxic substance in the mixture?

Under Cal/OSHA’s Process Safety Management (PSM) standards (specifically Title 8 §5189.1 for refineries and §5110.16 for other facilities), the Hierarchy of Hazard Control Analysis (HCA) is a formal, documented requirement that goes significantly beyond the traditional OSHA “inverted pyramid.”
While standard safety protocols often treat the hierarchy as a suggestion, Cal/OSHA makes it...

A new report from the EPA Office of Inspector General (May 6) highlighted that the U.S. Chemical Safety Board (CSB) is currently operating at only 40% board capacity (two out of five members), which restricts its ability to formally approve investigation reports and safety recommendations. The Clean Air Act Amendments of 1990 established that the CSB’s board shall consist of five board members, including...

The revised Heat National Emphasis Program (NEP), relaunched on April 10, 2026, represents a major shift in how OSHA handles heat-related enforcement. This isn’t just a renewal of the 2022 program; it is a full five-year directive (running through 2031) that gives inspectors more power to enter workplaces without a prior complaint.
OSHA no longer waits for a heatwave to act. The program defines...
