When lifting a heavy, sharp-edged item, what practices protect the rigging slings?

• A. Use edge protection and padding; select appropriate sling type; avoid direct contact with sharp edges and use protective devices.
• B. Avoid edge protection and rely on sling strength.
• C. Use only general-purpose slings with no padding.
• D. Rely on operator judgment to avoid sharp edges.

Answer: (D)

Edge protection and padding are essential when lifting a heavy, sharp-edged item because sharp edges can nick, cut, or abrade the sling as the load moves. Using edge protection such as edge guards or steel plates, plus padding to spread the load, keeps the sling material intact and maintains its rated strength. Selecting the appropriate sling type for the task and applying protective devices like corner protectors or wrap-around pads further prevents direct edge contact and distributes forces more evenly. This approach reduces the risk of sling failure by preventing concentrated cuts or abrasion that can degrade strength under load. Relying on operator judgment alone can miss damage that isn’t obvious and won’t guarantee protection, so edge protection, padding, and proper sling choice are essential for safe lifts.
