Synthetic slings should not be exposed to temperatures above which limit?

• A. 40°F
• B. 93°F
• C. 100°F
• D. 200°F

Answer: (D)

Synthetic slings are made from fibers that lose strength when exposed to heat. Heating these fibers can soften them and, over time, degrade coatings or any adhesives used in the sling, reducing its load-carrying capacity and raising the risk of failure during a lift. To prevent this, manufacturers specify a maximum service temperature. For most synthetic slings, that limit is 200°F (about 93°C). Staying below this temperature helps preserve the sling’s rated strength and safe performance.

The other temperatures listed don’t reflect the standard upper limit for synthetic web slings; they’re either well below the risk point or not the published maximum. If you’re working near heat sources, use slings rated for higher heat or implement protective measures to keep exposure under the 200°F limit.
