In LOTO, which step is Verify the lockout?

• A. Notify Employees
• B. Shut Down Equipment Properly
• C. Verify the lockout
• D. Bring the equipment back online

Answer: (C)

Verification of lockout confirms that all energy sources are isolated and cannot re-energize the system while work is performed. After you shut down the equipment and apply lockout devices to each energy source, this step involves checking that the isolation is effective—no energy can flow and the controls cannot be used to restart the machine. Techniques include attempting to start the equipment only after ensuring all energy paths are secured, and using appropriate testing methods to verify zero energy. This ensures the work can proceed safely without unexpected energization. The other actions are part of the process, but they do not confirm that the lockout is functioning; notifying others is about communication, and shutting down starts the process, while bringing the equipment back online is the release step after maintenance.
