Which statement best describes the purpose of Lockout/Tagout (LOTO) during maintenance near energized equipment?

• A. Increase power supply to verify function.
• B. Prevent unexpected energization and ensure a safe work environment.
• C. Document maintenance records only.
• D. Allow doors to operate during maintenance.

Answer: (B)

Lockout/Tagout protections during maintenance near energized equipment are about preventing unexpected energization and ensuring a safe work environment. By isolating the energy source, applying a physical lock to keep power off, and attaching a tag to warn that service is in progress, we make it clear that the equipment must not be operated until the lock is removed and the area is verified safe. This prevents the machine from starting up unexpectedly, protects workers from shock or arc flash, and controls the release of any stored energy when service is being performed. The process also involves verifying de-energization and ensuring only the authorized person who applied the lock can remove it, maintaining control over when the equipment can be re-energized. Other ideas aren’t aligned with this safety purpose. Energizing the system to verify function defeats the protection in place. Merely documenting maintenance records, while important, does not address the hazards of unexpected energization. Allowing doors or other moving parts to operate during maintenance ignores the risk of injury from unexpected movement and stored energy.
