What is the first step in safe lockout/tagout device removal after maintenance?

• A. Verify zero energy
• B. Secure tools
• C. Inform affected workers
• D. Remove LOTO devices

Answer: (A)

Verifying zero energy is the essential first step because you must ensure the equipment cannot restart or release stored energy before any lockout/tagout devices are removed. This check confirms that all energy sources—electrical, hydraulic, pneumatic, mechanical, and any stored or residual energy—have been isolated and are in a safe state. Only after this confirmation should you proceed to remove the LOTO devices. Skipping or delaying this verification creates the risk of sudden energization and serious injury. After the zero-energy condition is verified, you then handle the remaining steps (like informing affected workers and removing tools) before reenergizing the equipment.
