Process Safety Management, outlined in 29 CFR 1910.119, governs high-hazard chemical processes. While most SMBs fall below the 10,000-pound thresholds, cannabis extraction labs and cold storage facilities can trigger PSM-like expectations from insurers or state agencies. Elements include process hazard analyses, operating procedures, mechanical integrity, and emergency planning. Documenting scaled-down PSM elements shows regulators you understand the risk profile even if the full standard does not formally apply.
