A specific procedure for sling inspection is the best safeguard against injury, death and property damage. It is important that you employ a three stage level of inspection to ensure that slings are inspected with appropriate frequency. It is also important that all inspections must be done by trained and qualified personnel.
To detect possible damage, you should perform a visual inspection of the entire sling by making all parts of the sling readily visible. If necessary, remove dirt and grime so wires and components are visible.
Look for any of the conditions listed in the removal from service criteria.
