evidence of heat damage. (wire rope with a fiber core can be used up to 200F and IWRC can be used up to 400F)

other conditions, including visible damage, that cause doubt as to the continued use of the sling

missing or illegible sling identification

acid or caustic burns

excessive wear, nicks, or gouges. Minimum thickness on chain links shall not be below the values listed.

stretched chain links or components.

bent, twisted, or deformed chain links or components.

evidence of heat damage. Alloy chain slings can be used at up to 600F on a regular basis. They can be used at up to 1000F once, but then they have to be replaced.

excessive pitting or corrosion.

lack of ability of chain or components to hinge (articulate) freely.

wear — any wear exceeding 10% (or as recommended by the manufacturer) of the original section dimension of the hook or its load pin

deformation — any visibly apparent bend or twist from the plane of the unbent hook

throat opening — any distortion causing an increase in throat opening of 5% not to exceed 1⁄4 in. (6 mm)(or as recommended by the manufacturer)

inability to lock — any self-locking hook that does not lock

inoperative latch (if required) — any damaged latch or malfunctioning latch that does not close the hook’s throat
