What should be done before re-energizing equipment after maintenance under LOTO?

• A. Notify management.
• B. Inspect the work area.
• C. Re-energize only after clearance.
• D. Power up immediately.

Answer: (C)

Under LOTO, the energy source must stay isolated and de-energized until it’s proven safe to resume operation. The crucial step before re-energizing is obtaining formal clearance to release the lockout and restore power. This clearance is given by the authorized person who performed the lockout (or by the supervisor) after confirming the maintenance is finished, all hazards are addressed, guards and interlocks are in place, tools are removed, and the area is clear of personnel. This authorization ensures that it’s safe to re-energize and that no one is at risk of exposure to unexpected restart or stored energy. Notifying management alone isn’t sufficient, inspecting the area is important but does not substitute for official clearance, and powering up immediately is unsafe.
