Which conditions require compression hardware to be removed from service according to ASME B30.26?

• A. ALL OF THE ABOVE
• B. Missing or illegible identification
• C. Bent, twisted, distorted, stretched or cracked components
• D. Excessive pitting or corrosion

Answer: (A)

Under ASME B30.26, any condition that compromises the strength, integrity, or traceability of rigging hardware means it must be removed from service. Missing or illegible identification prevents verification of the correct rating, size, and inspection history, so you can’t confirm it’s safe to use. Bent, twisted, distorted, stretched, or cracked components indicate structural damage that can fail under load or unexpectedly, posing a serious hazard. Excessive pitting or corrosion eats away material, reducing strength and fatigue resistance, which lowers the margin of safety. Because each of these situations alone justifies taking the hardware out of service, all of the listed conditions together are reasons for removal. In practice, inspect before use, tag and isolate damaged items, and replace them rather than attempting to repair for continued service.
