Description: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. NIOSH investigators concluded that, to help prevent similar occurrences: 1) employers, crane owners, and operators should ensure that cranes are operated within their safe lifting capacities as recommended by the crane manufacturer's load chart; 2) crane owners should ensure that monitoring instruments used for guidance during hoisting operations are accurately calibrated and operating correctly; 3) employers should develop and implement safe work procedures to ensure that workers in or near the landing area of hoisted loads are notified when loads are in the air; 4) employers should develop and implement safe work procedures to ensure that workers and crane operators have a clear and complete understanding of the landing locations before loads are hoisted.
