What minimum operating temperature should synthetic web slings not be exposed to?

Explanation:
Synthetic web slings have a temperature rating because the polymer fibers change their behavior in the cold. When temperatures get very low, nylon and polyester fibers become stiffer and more brittle, reducing their ability to absorb shock and distribute loads. Moisture trapped in the fibers can also freeze, further weakening the sling. These factors can lead to fiber rupture or failure under load. Because of this, manufacturers specify a lower operating limit, commonly -40°F (-40°C) for many synthetic slings. Exposing a sling to colder temperatures can compromise safety. The other temperatures listed are not as cold and stay above that critical threshold, so they don’t present the same risk level.
