What is the correct final action in a lockout/tagout procedure after maintenance is completed?

• A. Remove locks/tags and restore energy.
• B. Re-energize equipment before removing tags.
• C. Leave locks in place until next shift.
• D. Ignore and leave system as is.

Answer: (A)

Lockout/tagout is about ensuring maintenance completes in a zero-energy, safe state and then returning the system to operation in a controlled way. The final action is to remove the lockout/tagout devices and restore energy once you have confirmed the work is finished, the area is clear, and all tools are removed. The person who applied the locks (or another authorized individual) should remove the devices only after verification that it’s safe to re-energize. After removing the devices, start-up is performed using normal startup procedures and affected personnel are informed. Re-energizing before removing tags defeats the protection the system provides and can lead to unexpected energy release. Leaving locks in place until the next shift keeps the equipment unnecessarily isolated and creates safety and startup problems. Ignoring the procedure is unsafe because it bypasses essential safeguards.
