What is the typical weather-related hazard to consider in rope operations?

• A. Dry conditions can cause more friction.
• B. Wet or icy surfaces reduce friction and moisture can degrade rope performance.
• C. High winds destroy rope.
• D. Sunlight weakens rope.

Answer: (B)

Weather affects rope operations mainly through how moisture and surface condition change friction and rope performance. When surfaces are wet or icy, friction between the rope, anchors, and equipment drops, so the rope can slip more easily and control becomes harder. That increased slip risk is a primary safety concern during any rope maneuver, whether lowering, hauling, or ascending. At the same time, moisture can affect the rope material itself—softening, swelling, or promoting wear over time—reducing strength and altering handling characteristics. So the combination of slick, wet surfaces and moisture-related rope effects creates the most significant weather-related hazard to manage. By comparison, dry conditions tend to increase friction rather than reduce it, which can change handling but isn’t the same hazard as slipping on wet surfaces. Wind and sun exposure can influence operations, but they don’t impact rope performance as immediately or directly as moisture and slickness do in typical rope work.
