Lockout/Tagout (LOTO) (Control of Hazardous Energy)
Lockout/Tagout is a safety procedure critical for the service and maintenance of machinery or electrical systems in cases where employees could be hurt by the unexpected start up, or energization of the equipment. It applies to all energy sources including mechanical, hydraulic, pneumatic, chemical, thermal, and even gravity. An effective Lockout/Tagout program can help protect workers by ensuring that machines and circuits are properly shut off (or de-energized) and not turned on(energized) again until the work is completed.
