RIGGING SAFE OPERATING
PROCEDURES
All personnel involved with the use of rigging
gear should be thoroughly instructed and trained to
comply with the following practices:
1. Wire rope slings must not be used with loads that
exceed the rated capacities outlined in enclosure (2) of
the COMSECOND/COMTHIRDNCBINST 11200.11.
Slings not included in the enclosure must be used only
according to the manufacturer’s recommendation.
2. Determine the weight of a load before
attempting any lift.
3. Select a sling with sufficient capacity rating.
4. Examine all hardware, equipment, tackle, and
slings before using them and destroy all defective
components.
5. Use the proper hitch.
6. Guide loads with a tag line when practical.
7. When using multiple-leg slings, select the
longest sling practical to reduce the stress on the
individual sling legs.
8. Attach the sling securely to the load.
9. Pad or protect any sharp comers or edges the
sling can come in contact with to prevent chaffing.
10. Keep slings free of kinks, loops, or twists.
11. Keep hands and fingers from between the sling
and the load.
12. Start the lift slowly to avoid shock loading
slings.
13. Keep slings well lubricated to prevent
corrosion.
14. Do not pull slings from under a load when the
load is resting on the slings; block the load up to remove
slings.
