Materials Handling (including Gear and Equipment for Rigging) >> Shackles and Hooks
Shackles and hooks are rigging components used to attach loads and slings to lifting devices. These items along with ropes, chains, and slings make up the "rigging gear."
Note: Confined space entry is one of the leading hazards associated with barge cleaning. Review the Shipbreaking: Confined or Enclosed Spaces and Other Dangerous Atmospheres chapter for information on how to protect workers from this hazard.
Failure of shackles or hooks while loads are being lifted or moved, may cause serious injuries.
