Synthetic lifting slings commonly are used for rigging.
The most commonly used synthetic slings are made of nylon or polyester yarns that protect the load, have adequate strength, are convenient, and economical.
Each sling will be marked by the manufacturer to include the rated load capacity for each type of hitch used and the type of synthetic web material.
A qualified person should inspect synthetic slings prior to each use.
Synthetic slings should be removed from service, if any of the following are visible:
Missing or illegible sling identification.
Acid or alkali burns.
Melting, charring, or weld spatter on any part of the sling.
Holes, tears, snags, or embedded particles.
Excessive or abrasive wear.
Knots in any part of the sling.
The presence of red core yarns.
Safe Practices for Synthetic Web Slings
Consider the following safe practices prior to and while using synthetic web slings:
Determine the weight of the load and ensure that it is within the sling’s rated capacity.
Select a sling appropriate for the type of load, hitch, and environment.
Protect the sling from being cut by sharp corners, edges, protrusions, or abrasive surfaces.
Do not drag slings on the floor or other abrasive surfaces.
Do not twist, tie into knots, or join by knotting.
Keep personnel and body parts away from the area between the sling and the load.
Ensure that personnel stand clear of the suspended load.
