Mine Safety and Health Administration Metal and Nonmetal Mine Safety and Health Report of Investigation: Surface Nonmetal Mine (Sand and Gravel). Fatal Falling Material Accident, November 10, 2006. Seppi Brothers Concrete Products Corporation, Jammer

摘要

Christopher M. Luecken, loader operator, age 41, was fatally injured on November 10, 2006. He was struck by the head pulley work platform of a mobile radial stacker conveyor when the main truss failed. The failure of the truss caused the conveyor to buckle, allowing the head pulley section to fall to the ground. The conveyor was being prepared for movement to another location when the accident occurred. The accident occurred because management modified the manufacturer's field conveyor design and compromised the structural integrity of the conveyor. Management did not consult the manufacturer of the conveyor or follow established engineering principles when making the modifications.
