Lockout/Tagout refers to the procedures established for Control of Hazardous Energy, as described by the Occupational Safety and Health Administration (OSHA) under Federal Registry 29 CFR 1910.147.
Lockout/Tagout ensures employee safety during inspection, Maintenance, or service of equipment by controlling all energy flow to and from the equipment.
To achieve system Lockout, all energy sources are turned off or disconnected, and Stored Energy is released, restrained, or Dissipated. A lock or Lockout Device applied to each Energy Source prevents accidental startup.
Tagout refers to application of warning tags to energy sources to ensure the equipment is not restarted until service has been completed. Tags may be used with locks for enhanced safety assurance. Where Lockout is not possible, tagout may be an alternative. Tagout alone is not as secure as is lockout.
