Which steps are included in securing and tagging out a crane for maintenance?

• A. Lock out all power sources, tag out with communication to all affected personnel, verify isolation, and secure the crane to prevent movement; restrict access to authorized personnel only.
• B. Power down the crane and begin maintenance without tagging or isolating power.
• C. Tag out the crane after completing the maintenance and testing.
• D. Shut off power only and continue operations with a spotter nearby.

Answer: (A)

Securing and tagging out a crane before maintenance is all about preventing unexpected energy release and movement while work is being done. The best practice starts with locking out every energy source so the crane cannot be energized. A tag is then placed to communicate that maintenance is in progress and that the equipment must not be operated. Verifying isolation using proper checks confirms that all energy paths are truly dead, leaving no stored or residual energy that could re-energize the crane. Securing the crane to prevent movement adds a physical barrier so it cannot be moved or shifted accidentally during maintenance. Finally, restricting access to authorized personnel keeps the control measures in place and prevents someone from bypassing the lockout. Together, these steps reduce the risk of injury or damage and ensure a safe maintenance environment. The other approaches miss one or more of these essential elements, such as not isolating or tagging, or attempting maintenance while power is still capable of energizing the crane.
