Why is edge protection important when rigging, and what measures are common?

• A. Edges can cut or damage slings; use wooden edge protection, rubber mats, steel plates, corner guards, or padding; ensure protection is sized for the load path and environment.
• B. Edges have no effect on slings.
• C. Only use steel plates.
• D. Padding alone is sufficient.

Answer: (A)

Edges can cut or abrade slings, especially under load, which weakens the sling and can lead to a failure. Protecting the contact area preserves sling strength, maintains safe lifting capacity, and reduces the risk of the load shifting or slipping due to damaged rope or strap. Common measures include edge protection placed along the contact path: wooden edge protection with hardwood boards to give a solid, smooth surface; rubber mats or padding to cushion contact and reduce friction; steel plates or angle irons to span sharp edges and distribute the load; corner guards to cover exposed corners and prevent snagging. The protection should be sized to fit the exact load path and environment, meaning it must cover the full contact length, withstand the expected forces, and be appropriate for temperatures, chemicals, or outdoor conditions. Securing the protection so it stays in place during lifting is also essential. Using these protections together, chosen for the specific edge and load, helps keep slings in good condition and supports safer rigging operations.
