Worker inspecting lines and slings
Inspect lines and slings often.

Location and Type

Maintain a log of all lifting slings on the rig. Inspections prior to use and each year are required by law. Good practice instruct that slings should be marked by the manufacturer with the safe working load and the date of manufacture.

Tables of working load by size and type of wire rope should be available in case tags are damaged.

Slings should be stored in a clean, dry place where they are protected from the weather. In addition, slings should be stored away from heat and chemicals that may remove the lubricants from the cable.
