A rigger was using a tag line to help position a large piece of ship's equipment. His working surface was a grating level next to an open cargo area. When the primary rigging gear broke loose, it caught the rigger's foot, causing him to lose his balance. He fell into the water-filled cargo area (tanks) and drowned.
Analysis and Preventive Measures
The cause of the accident was a rigging failure; the line was improperly attached to the hook. However this accident became a fatality because the rigger was not tied off properly. Fall protection would have prevented his death.
