Exposure to which type of light can damage synthetic ropes?

• A. Infrared
• B. Ultraviolet/sun
• C. Incandescent
• D. Fluorescent

Answer: (B)

Ultraviolet light from sunlight can damage synthetic ropes because it carries enough energy to break the chemical bonds in the polymer fibers. This photodegradation leads to chain scission and oxidation, weakening the rope, making it stiff or brittle, and causing surface cracks. While other light types can heat rope or contribute minor exposure, UV radiation is the primary factor in outdoor aging of synthetic rope. To protect ropes, limit direct sun exposure when possible, store them out of UV light, and inspect for signs of aging such as stiffness, cracking, or chalky surfaces after outdoor use.
