DANGERS

What Should You NOT Do 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. DO NOT operate a damaged, malfunctioning or unusually performing hoist. DO NOT operate the hoist until you have thoroughly read and understood the manufacturer's Operating and Maintenance Instructions or Manuals. DO NOT operate a hoist which has been modified without the manufacturer's approval. DO NOT lift more than rated load for the hoist. DO NOT use hoist with twisted, kinked, damaged, or worn load chain or wire rope. DO NOT use the hoist to lift, support, or transport people. DO NOT lift loads over people. DO NOT operate a hoist unless all persons are and remain clear of the supported load. DO NOT operate unless load is centered under hoist. DO NOT attempt to lengthen the load wire rope or chain or repair damaged load wire rope or chain. DO NOT operate hoist when it is restricted from forming a straight line from hook to hook in the direction of loading.

What You Should Do While Operating A Hoist. Take up slack carefully - ensure load is balanced and load holding action is secure before continuing. 2. Shut down a hoist that malfunctions or performs unusually and report such malfunction. 3. Warn personnel of an approaching load. 4. Check brake function by tensioning the hoist prior to each lift operation. 5. Use hook latches. Latches are to retain slings, chains, etc. under slack conditions only. 6. Ensure the hook latches are closed and not supporting any parts of the load. 7. Ensure the load is free to move and will clear all obstructions. 8. Avoid swinging the load or hook. 9. Ensure hook travel is in the same direction as shown on the controls. 10. Inspect the hoist regularly, replace damaged or worn parts, and keep appropriate records of maintenance. 11. Use the hoist manufacturer's recommended parts when repairing the unit. 12. Lubricate load wire rope or chain per hoist manufacturer's recommendations. 13.

A PAD EYE LIFTING LUG

Case History #8 Welder Struck by Plate A welder was working with the ship repair crew which was fitting a new 0. 5 -inch thick steel plate on the bottom hull of a tanker. The crew was working on an 8 -foot by 40 -foot plate which would patch the outboard port side between the center line and the bilge. Three chain-falls were used to lift the plate: two, 3 -ton capacity chain-falls and one, 1 ton chain-fall.

When the plate was raised, it was off by six inches and did not fit up to the hull. The welder began welding a pad eye to the edge of the plate so that a come-along could be attached and allow the plate to be pulled into position. While the welder was welding the pad eye, one of the interior pad eyes failed, resulting in a chain reaction that caused the plate to drop on the welder, crushing him.

The weight of the steel plate Using an online steel plate calculator I determined that the steel plate being installed by the ships repair crew weighed 6527. 2 LBS

Possible ways to prevent this type of accident: Do not work under suspended loads. Complete pre-work plan including hazard assessment, sequence of events and possible danger areas. Use blocks or shoring to support the load while work is being done. Ensure that the lift plan is approved and utilized.

Ensure that rigging equipment meets or exceeds requirements of lift and that a safety factor has been built in. Ensure that chain-falls are the same capacity when positioning loads. Ensure that the pad eyes are the appropriate size for their intended use and that the pad eyes are welded, not tack welded.
