OSHA PSM (29 CFR 1910.119) applies to facilities handling highly hazardous chemicals above threshold quantities. The 14 elements cluster around a few high-citation areas: process safety information (element 2), process hazard analysis (element 4), mechanical integrity (element 8), and management of change (element 10).
Element 2 (Process Safety Information) is foundational — without accurate P&IDs, relief system designs, and chemical hazard data, every other element fails. Element 4 (PHA) requires revalidation every 5 years. Element 8 (Mechanical Integrity) is the most-cited element.
