Which of the following can damage webbing or rope lanyards?

The correct answer encompasses all of the listed factors, which can each contribute to damaging webbing or rope lanyards.

Exposure to extreme temperatures can degrade the materials used in these safety devices, making the fibers brittle or causing them to lose their strength. High temperatures can cause melting or alteration in properties, while low temperatures can make them stiff and less flexible.

Prolonged exposure to sunlight can lead to UV degradation. Many types of webbing and rope lanyards are made from synthetic materials that can break down and lose their integrity when subjected to UV rays over time. This process can weaken the fibers and reduce their load-bearing capacity.

Contact with sharp edges poses a significant risk as well; any abrasion or cutting against a sharp edge can compromise the structural integrity of the lanyard. If a lanyard gets nicked or cut, it may fail to support someone’s weight when needed.

Understanding these risks emphasizes the importance of regular inspection and maintenance of safety gear used in construction and fall prevention, ensuring that they remain effective and reliable.
