Coverage
OSHA 29 CFR 1910.119 (PSM) applies to processes that contain a threshold quantity of a highly hazardous chemical. EPA 40 CFR Part 68 (RMP) layers on top for the same chemical list but with community-impact reporting. If you are PSM-regulated, you are almost always RMP-regulated.
The 14 elements
- Employee participation — written plan, workforce consulted on PSM activities.
- Process safety information — chemical, technology, equipment documentation.
- Process hazard analysis (PHA) — HAZOP / What-If / FMEA every 5 years.
- Operating procedures — written, current, accessible.
- Training — initial + refresher on process and procedures.
- Contractors — selection, training, audit.
- Pre-startup safety review (PSSR).
- Mechanical integrity — equipment inspection and testing.
- Hot work permit.
- Management of change (MoC).
- Incident investigation — recordable process-safety incidents.
- Emergency planning and response.
- Compliance audits — every 3 years.
- Trade secrets — protected but disclosable to those who need it.
