Fatality Assessment and Control Evaluation (FACE) Report: Welder Dies After BeingStruck by a Three-Ton Steel Roof Truss, South Carolina, February 29, 1996

摘要

A 27 year old man working as a welder died after being pinned under a 3 ton, 65foot long steel roof truss in South Carolina. The victim had worked for a steel erection company for one and a half weeks prior to the accident. The company was contracted to fabricate and erect steel roof trusses for the roof of an airplane hangar. Trusses had been cut in half for shipment to the site. At the work site, 12 trusses had been welded and placed on support beams for the roof of the hangar. One half of a truss was being lifted with a crane. When the crane cable contained enough slack, the victim lossened the chokers and slid them outwards toward the truss ends. The truss half tipped and fell toward him, pinning him against a pile of tubular steel. He was pronounced dead at the scene; his death was due to massive crushing chest injuries. It was recommended that materials being lifted or positioned by a crane or other lifting machine be supported at all times, that access and egress routes at a work site be free from unnecessary materials, and that ways to perform all tasks be evaluated during prejob planning to arrive at the safest work environment.
