Lockout/tagout programs are designed to prevent accidental startup of machines or equipment, and to prevent the release of stored energy during servicing or maintenance. Through the use of specific procedures that involve applying locks and/or tags as direct controls, equipment is isolated from energy sources and injuries to workers are prevented.

The Occupational Safety and Health Administration (OSHA) requirements for the Control of Hazardous Energy (Lockout/Tagout) apply to all servicing and maintenance of equipment where accidental startup or unexpected release of energy can occur. Departments involved in these activities are responsible for the development and implementation of a lockout/tagout program. Lockout/Tagout requirements do not apply to work on cord and plug connected equipment if you can maintain personal control of the plug.
