Workforce reductions, restructurings, contractor staffing changes, role eliminations, and outsourcing of safety-critical functions can constitute changes that affect process safety and may therefore require MOC treatment. OSHA has increasingly addressed organizational change in the context of PSM, reflecting industry experience showing that human and organizational factors contribute to major incidents. Eliminating a process safety engineer position, reducing control room staffing, or transferring maintenance responsibilities to a contractor without evaluating the impact on safety systems are the kinds of changes these letters address.

⚡ Key Compliance Takeaway

Before announcing a restructuring, ask whether the change affects your ability to execute any PSM program element. If so, open an MOC. Include the safety impact in the business case analysis, not just in a retrofit review after the org chart is already posted.
