When is it appropriate to remove a lockout device or tag?

• A. Before starting work
• B. After the work is complete and energy sources are verified to be restored and safe
• C. Immediately after turning off the switch
• D. Never remove lockout

Answer: (B)

Lockout devices and tags are used to protect workers from unexpected energization while maintenance or servicing is done. The right time to remove a lockout device or tag is after the work is finished and you have verified that all energy sources have been isolated and are safe to restore. This means the equipment is de-energized, any stored energy (like capacitors or springs) has been released, and the system has been checked to confirm it’s safe to operate again. Only then should the person who applied the lock or tag remove it, and re-energize the equipment in a controlled way. Removing it too early or leaving it in place indefinitely both create danger or unnecessary delays.
