About PSM

Process Safety Management (PSM) is a set of interrelated principles for managing the hazards associated with process industries. These principles are designed to reduce the frequency and potential severity of process incidents that could result from the accidental release of hazardous fluids (oil, gases, chemicals) and other energy sources. PSM approaches are composed of design standards, engineering studies, equipment specification, organizational capability and operational procedures, audit programs, safety case development and a host of other methods aimed at preventing accidents that can cause serious harm to people, environment and assets. CCPS requires PSM programs to contain the following 20 key elements that provide a comprehensive management system to handle risks in chemical plants and other facilities:
