Lockout/tagout for safety during maintenance, service and repair work

A person can be seriously injured, even killed, when working on a machine or equipment if the hazardous energy sources are not controlled.

When performing maintenance, service or repair work on equipment, processes or systems, all hazardous energy sources must be controlled using lockout/tagout procedures and OSHA-approved locks and tags to protect those impacted from the unintended start-up or release of stored energy. Common hazardous energy sources include electrical, hydraulic, pneumatic, mechanical, thermal, chemical or gravitational.
