Fatality Assessment and Control Evaluation (FACE) Report: Carpenter Dies After Being Struck by Uncontrolled Concrete Bucket When Crane Tips Over in Ohio

摘要

On October 13, 1999, a 50-year-old male carpenter (the victim) at a municipal construction site died after he was struck by a loaded concrete bucket during a crane tip-over. The victim was removing forms from a newly constructed concrete wall while a concrete finishing crew was filling empty forms about 15 to 20 feet away. Concrete was being hoisted from street level with a crawler-mounted mobile crane and landed under the direction of a roof-top spotter. As the crane operator hoisted a bucket load of concrete, swung it over the roof, and boomed out toward the empty forms, the crane lost stability, tipping toward the victim. When the crane operator realized what was occurring, he radioed a warning to the spotter who relayed the warning to roof-top workers. The victim had started to move when the uncontrolled concrete bucket swung toward him, striking his head and shoulder. Workers notified emergency personnel who responded within 6 minutes. The victim was pronounced dead at the scene.
