Name three common types of synthetic fiber slings and one safety consideration for each.

• A. Nylon, polyester, and polypropylene slings; safety: avoid heat exposure, protect from sharp edges, and inspect for cuts or fraying.
• B. Nylon, Kevlar, and cotton slings; safety: avoid heat exposure, protect from sharp edges, and inspect for cuts or fraying.
• C. Nylon, polyester, and steel slings; safety: avoid heat exposure, protect from sharp edges, and inspect for cuts or fraying.
• D. Cotton, polyester, and polypropylene slings; safety: avoid heat exposure, protect from sharp edges, and inspect for cuts or fraying.

Answer: (A)

Synthetic fiber slings are commonly made from nylon, polyester, and polypropylene. For safety, nylon slings should avoid heat exposure because heat can weaken or melt the fibers. Polyester slings require protection from sharp edges to prevent cutting or abrading the fibers. Polypropylene slings should be inspected for cuts or fraying to catch damage before it leads to failure. The other options mix in non-synthetic materials or metals, or include natural fibers, which aren’t the typical three common synthetic options.
