Avoid rubbing fall protection equipment on which surfaces?

• A. Abrasive surfaces / sharp edges
• B. Smooth metal surfaces
• C. Hot surfaces
• D. Wet surfaces

Answer: (A)

Rubbing fall protection equipment on abrasive surfaces or sharp edges is dangerous because those surfaces wear away the fibers of rope and the webbing of harnesses or lanyards. Abrasion and cuts create weak spots that can fail under load during a fall. Edge contact can also gouge fibers and concentrate stress, dramatically reducing strength. To keep gear intact, keep it away from rough, sharp edges and use edge guards or protective routing when edges can’t be avoided. While smooth metal, hot, or wet surfaces raise other safety concerns (slipping, burns, or general grip issues), the direct risk to gear strength from rubbing is greatest with abrasive surfaces and sharp edges, which is why this option is the correct focus.
