Slings made from synthetic materials that should not be exposed to temperatures above 200°F or below -40°F are called what?

• A. Web Slings
• B. Synthetic Slings
• C. Loop Eye
• D. Sling Angle

Answer: (B)

Synthetic slings have defined temperature limits to protect their strength. Slings made from synthetic fibers can lose load-carrying capacity if exposed to heat above about 200°F, which can cause weakening, melting, or other damage to the polymer fibers. Extreme cold below -40°F can make those fibers brittle and prone to cracking or sudden failure. Because these temperature ratings apply to the material itself, the classification that fits is synthetic slings. Web slings are a common type of synthetic sling, but the question’s focus is on the material category rather than a specific construction. Loop eye and sling angle describe features or geometry, not the material class.
