Which type of slings is vulnerable to degradation from ultraviolet light?

Synthetic fiber slings are composed of materials like nylon or polyester, which have specific vulnerabilities, including degradation from ultraviolet (UV) light exposure. UV radiation can break down the chemical structure of these synthetic fibers, leading to a loss of strength, flexibility, and overall integrity of the sling. Over time, this degradation can significantly compromise the sling's performance and safety when used in rigging and hoisting operations.

In contrast, steel slings, chain slings, and wire rope slings are made from metal materials that are not susceptible to UV degradation. While these metal slings may experience other forms of wear or corrosion, they remain intact and functional under UV exposure, making them more durable in environments where sunlight is a factor.
