ASME B30.10: Any hook that has any visible bend or twist from the plane of the unbent hook shall be?

• A. Repaired or replaced
• B. Recycled
• C. Reclassified
• D. Discarded

Answer: (A)

Visible bend or twist in a hook means the load path and geometry may be compromised, increasing the risk of fatigue cracking or sudden failure under load. ASME B30.10 requires that any hook with such deformation be removed from service and handled in a way that restores or preserves safety. If the hook can be brought back to its proper shape and its integrity restored, it can be repaired by a qualified person and then re-inspected (and tested as required). If the damage cannot be safely repaired, the hook must be replaced. This approach protects lifting operations by ensuring the hook either returns to its intended geometry and strength or is taken out of service entirely. Recycled, reclassified, or simply discarded without repair do not align with the standard’s emphasis on maintaining a safe, functional hook through repair or replacement.
