PSM — Process Safety Management

A systematic management framework for preventing major process-related incidents involving hazardous materials.

Definition

Process Safety Management (PSM) is a structured management framework that integrates engineering, operational and organizational practices to identify, evaluate and control hazards associated with hazardous process materials and operations. It establishes the policies, procedures and management processes required to prevent major accidents and continually improve process safety performance throughout the asset lifecycle.

Why It Matters

Process Safety Management provides the organizational framework for preventing major process-related incidents and continuously improving process safety performance.

In Practice

Process Safety Management was formalized through OSHA 29 CFR 1910.119 (Process Safety Management of Highly Hazardous Chemicals), which established the foundational management framework subsequently adopted and expanded by organizations such as CCPS, API and regulatory authorities worldwide. Modern PSM systems commonly incorporate Process Safety Information, Process Hazard Analysis, Management of Change, Mechanical Integrity, Operating Procedures, training, incident investigation and emergency preparedness.

Common Misuse

Process Safety Management establishes the management framework for controlling process hazards, whereas Process Safety Information provides the technical information supporting those activities.
