For that average joe, below are great tips that may render a sling “out of service”:
The tag on the sling is illegible or missing
Virtually any burns, melting, charring, or weld spatter for the sling
Holes, tears, snags or cuts inside the webbing (Red Alert yarns may be showing)
Stitching is broken or worn
Sling may be damaged by abrasion/friction
Sling has become tied in a knot (this is the definite no-no!)
Some of the metal fittings for the sling are distorted, stretched, have excessive pitting or corrosion

Inspecting the sling happen on every standby time with the sling. A fast overview looking for items above is generally suitable however the sling moves via a thorough inspection periodically through its usage.

Red warning yarns, or “Red Alert” yarns, are often sewn to the core from the webbing. In case a lifting sling may be cut or damaged enough that you simply see these yarns, the lifting sling needs to be removed from service immediately because cut has resulted in the load-bearing yarns. Quite simply, the strength of the sling has become compromised dramatically. Slings with damaged may never be repaired, but disposed of properly. If your metal fittings with the sling still seem useful but the webbing is broken, you’ll be able to cut the fittings loose from the webbing and also have them submitted in to a manufacturer to become re-sewn with new webbing (however, the fittings have to be proof-tested for strength at this juncture).
Written documentation of periodic inspections ought to be kept on file all the time. The documentation should note the sling’s identification, description and condition on every inspection. Never forget, “When uncertain, remove from service.”
