In lockout/tagout, what step comes after completing the work and before power is restored?

• A. Remove lockout/tagout devices
• B. Notify supervisor only
• C. Restore power
• D. Document the work and verification of zero energy

Answer: (A)

In lockout/tagout, the sequence centers on keeping energy isolated while work is done and then safely restoring power. After the work is finished and you’ve confirmed zero energy, the next step is to remove the lockout/tagout devices. This removal allows the equipment to be energized again and is normally done by the authorized person who applied the devices, ensuring the area is clear and all tools or other hazards have been addressed. Only after the devices are removed and clearance is confirmed should power be restored. Notifying the supervisor or documenting the work are important parts of the process, but they do not by themselves enable re-energizing the equipment. Restoring power without removing the devices would defeat the safety controls.
