At rated capacity, a treated nylon sling stretches approximately 10%, whereas a treated polyester sling will stretch approximately 7%. Nylon's extra stretch helps to avoid shock loading. The lesser stretch of polyester makes load control easier by reducing bounce. In a chemical environment, nylon should not be used around acids or bleaching agents while polyester should not be used near aldehydes.

Dirt in a web sling can promote internal abrasion that can reduce sling strength and possibly shorten sling life.
Cleaning of synthetic slings is addressed in technical bulletin G-31 Clean r1-07
A sling that can be identified as a Lift-All sling can be retagged if it otherwise passes inspection.
Unprotected slings should not be used since the forks may cut slings under load. Single Fork Hooks
attached to forklift forks are designed specifically for this purpose.
Since the eyes are essentially basket hitches, there is no need for two-ply eyes on a two-ply sling.
