Alert 05 – 09 Improper Rigging Results in Fatality
WHAT HAPPENED:
During the start-up phase of a drilling program, it was necessary to stand back the diverter assembly on the drill floor. In an attempt to stand back the diverter assembly, the crew attached a snatch-block and sling to a guardrail which was then connected to an air-hoist. When the load was applied from the air-hoist, the guard rail broke free from the deck and flew across the drill floor, where it struck the IP in the head, resulting in a fatality.
