Exposure to which type of light can damage synthetic ropes?

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

Answer: (B)

UV radiation from sunlight is the main threat to synthetic ropes. The polymers in these ropes absorb UV photons, triggering photo-oxidative reactions in the presence of air. This process breaks polymer chains and causes embrittlement, color fading, and a drop in tensile strength over time, especially with outdoor exposure. Heat from infrared light can speed up aging but doesn’t cause the same direct chemical damage, and incandescent or fluorescent lights emit mostly visible light with little UV, so they’re not the primary culprits.
