What is Lockout/Tagout (LOTO) and why is it critical for lifts in electrical work?

• A. A set of procedures to isolate and verify zero energy and to prevent accidental re-energizing during work.
• B. A maintenance schedule.
• C. A method to tag loads for identification.
• D. A training course.

Answer: (A)

Lockout/Tagout is a safety practice that ensures electrical equipment is completely isolated from its energy sources and cannot be energized while maintenance or repair work is being done. It involves locking the energy-off device (so it cannot be turned back on) and placing a tag to warn others not to restart the equipment, along with confirming there is zero energy present. This prevents unexpected startup or the release of stored energy that could injure a worker.

For lifts, this is crucial because a machine or its control circuits could move, drop, or energize unexpectedly if power is restored during service. Lockout/Tagout protects technicians as they inspect, repair, or adjust hoists, motors, or control panels, ensuring only the person who applied the lock can remove it and re-energize the system after safety checks.

This isn’t merely a maintenance schedule, nor is it just tagging for identification or a training course. It’s the actual procedure to isolate energy and prevent re-energizing during work.
