Slings require special attention because they may be subjected to:

Slings must be watched closely because their strength can be compromised by a range of damage modes that can occur during lifts. The best choice highlights the combination of severe wear, abrasions, impact loading, crushing, and overloading. Each of these can weaken the sling or create hidden flaws: wear and abrasion thin the material or remove protective layers, abrasions can cause cuts that propagate under load, impact loading introduces sudden peak forces that can initiate cracks, crushing happens when the sling is pinched or pressed against sharp edges, and overloading pushes the sling past its rated capacity. Any one of these issues can lead to unexpected failure even if the sling appears fine at a glance. Heat exposure, wind loading, or chemical corrosion can affect slings too in certain situations, but they don’t cover the full spectrum of damage mechanisms that require heightened vigilance like the listed combination does.
