Inspection
Check for burn marks or melting that may have occurred around welding activities. Slings that are used around welding should be protected from the heat and the sparks and should never be installed on hot iron.
Check for corrosion from chemicals or exposure to water.
Look for flattening or crushing of the cable that would indicate damage to the internal wire rope core. Any damage to the internal core would be cause to take the sling out of service.
Some companies use a color code system to identify what year a sling was inspected. Some larger slings may last for many years and would need to be inspected, recorded, and color coded for the current year.
