Sharp or abrasive surfaces on a work site are hazardous because they may

• A. cause injury to self and others and damage the rope access system
• B. cause fatigue
• C. improve grip
• D. have no effect

Answer: (A)

Sharp or abrasive surfaces create real safety risks because they can injure people and damage the rope access setup. When a rope slides over a sharp edge, it can become nicked or frayed, weakening its strength and raising the chance of rope failure. At the same time, exposed skin can be cut or scraped, and gloves don’t eliminate the danger entirely. This combination—threat to personnel and threat to the rope system—makes such surfaces a primary hazard on rope access jobs. Other ideas don’t fit as well: friction-related fatigue isn’t the main hazard, edges don’t improve grip (they typically make handling more dangerous), and stating there’s no effect ignores the clear risks to both people and equipment. To reduce risk, use edge protection, route ropes away from sharp points, and regularly inspect for abrasion.
