When inspecting fiber rope slings before use, which conditions should be checked?

• A. Discolored fibers
• B. Charred or melted spots
• C. Cuts
• D. All of these

Answer: (D)

This question focuses on recognizing damage indicators in fiber rope slings during pre-use inspection. Any sign of deterioration—discolored fibers, heat damage like charred or melted spots, or cuts—means the sling’s strength is compromised. Discoloration can indicate chemical exposure, aging, or UV damage that weakens fibers. Charred or melted areas show heat damage, which can reduce strength even if the rope looks mostly intact. Cuts create weak points where the rope can fail under load. Because each of these conditions reduces the sling’s ability to safely carry a load, all of them require removing the sling from service and using a replacement.
