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 ...
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'.

The fire led to legislation requiring improved factory safety standards and helped spur the growth of the International Ladies' Garment Workers' Union, which fought for better working conditions for sweatshop workers in that industry. February 20, 1947: O'Connor Plating Works disaster. A chemical explosion killed seventeen people in Los Angeles.
Protection through the use of safety layers. A process plant shutdown system is a functional safety countermeasure crucial in any hazardous process plant such as oil and gas production plants and oil refineries. The concept also applies to non-process facilities such as nuclear plants. These systems are used to protect people, assets, and the ...
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.
In more recent times, the expressions "occupational safety and health" and "occupational health and safety" have come into use (and have also been adopted in works by the ILO), [13] based on the general understanding that occupational health refers to hazards associated to disease and long-term effects, while occupational safety hazards are ...
Process safety management is an analytical tool focused on preventing and managing releases of hazardous materials in industrial plants. Safety margins/safety factors, for instance, a product rated to never be required to handle more than 100 kg might be designed to fail under at least 200 kg, a safety factor of two.
