Hazardous energy in occupational safety and health is any source of energy (including electrical, mechanical, thermal, chemical, hydraulic, and pneumatic sources of energy) that "can be hazardous to workers", such as from discharge of stored energy.
Several standards are defined for control of hazardous energy, or lockout/tagout. In 1995 OSHA was successful in promulgation of regulations for utility. [2] In 1994 were established Electrical Safety Foundation International non-profit organization dedicated exclusively to promoting electrical safety at home and in the workplace. [3]
Exposure to hazardous energy is controlled completely by unplugging the equipment from an electric outlet and where the employee doing the service or maintenance has exclusive control of the plug. This applies only if electricity is the only form of hazardous energy to which employees may be exposed.
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.
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.
Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over ...
Permit-to-work is an essential part of control of work (CoW), a structured communication mechanism to reliably communicate information about hazards, control measures, and so on. During critical maintenance activities, good communication between management, supervisors, operators, and maintenance staff and contractors is essential.
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.
