Lockout and Tagout signs protect against the unexpected energization or start up of machines and equipment that could injure employees during service or maintenance.

Lockout signs and labels identify equipment that may not be operated for safety reasons, and describe how to render machines and equipment inoperative.

lockout procedure labels

Lockouts are used to identify equipment, controls, MCCs, breakers, etc. that have been removed from service and which may not be operated. In many cases locks are used to prevent the locked-out device from being operated.

Tagout are used when equipment is incapable of being shut down. Tagout indicate that the equipment being controlled may not be operated until the Tagout is removed.

According to OSHA, both lockout and Tagout signs need to be standardized within the facility by either color, shape or size.
