Process safety management (PSM) is a practice to manage business operations critical to process safety. It can be implemented using the established OSHA scheme [1] or others made available by the EPA, [2] AIChE's Center for Chemical Process Safety, [3] or the Energy Institute. [4] PSM schemes are organized in 'elements'.
Process Safety Management of Highly Hazardous Chemicals is a regulation promulgated by the U.S. Occupational Safety and Health Administration (OSHA). [1] It defines and regulates a process safety management (PSM) program for plants using, storing, manufacturing, handling or carrying out on-site movement of hazardous materials above defined amount thresholds.
Process safety is an interdisciplinary engineering domain focusing on the study, prevention, and management of large-scale fires, explosions and chemical accidents (such as toxic gas clouds) in process plants or other facilities dealing with hazardous materials, such as refineries and oil and gas (onshore and offshore) production installations ...
Permit-to-work is also a core element of integrated safe system of work (ISSOW) systems, that along with risk assessment and isolation planning, enable as low as reasonably practicable (ALARP) reduction of unsafe activities in non-trivial work environments. Permit-to-work adherence is essential in process safety management.
It is one of the elements of OSHA's program for Process Safety Management. There are several methodologies that can be used to conduct a PHA, including checklists , hazard identification (HAZID) reviews, what-if reviews and SWIFT , hazard and operability studies (HAZOP), failure mode and effect analysis (FMEA), etc. PHA methods are qualitative ...
An occupational safety management system (OSMS) is a management system designed to manage occupational safety and health risks in the workplace.If the system contains elements of management of longer-term health impacts and occupational disease, it may be referred to as a occupational safety and health management system (OSHMS) or occupational health and safety management system (OHSMS).
Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [a] It is a widely accepted system promoted by numerous safety organizations.
U.S. OSHA regulations regarding "Process safety management of highly hazardous chemicals" (especially Appendix C). FAA Order 8040.4 establishes FAA safety risk management policy. The FAA publishes a System Safety Handbook that provides a good overview of the system safety process used by the agency.
