Holes, tears, snags or cuts within the webbing (Red Alert yarns might be showing)
Stitching is broken or worn
Sling may be damaged by abrasion/friction
Sling continues to be tied inside a knot (it is a definite no-no!)

Red warning yarns, or “Red Alert” yarns, are occasionally sewn to the core of the webbing. If your lifting sling has been cut or damaged enough that you just see these yarns, the lifting sling should be taken out of service immediately since the cut has progressed into the load-bearing yarns. In other words, great and bad the sling has become compromised dramatically. Slings with damaged may do not be repaired, but discarded properly. If your metal fittings in the sling still seem useful but the webbing is broken, you can cut the fittings loose in the webbing and possess them sent in to some manufacturer being re-sewn with new webbing (however, the fittings has to be proof-tested for strength at this juncture).
Written documentation of periodic inspections ought to be continued file at all times. The documentation should note the sling’s identification, description and condition on every inspection. Bear in mind, “When in doubt, remove from service.”
