Abstract: Employee #1 removed his hard hat so he could wear the goggles required for using the cutting torch and proceeded to remove the footing of a raceway from the metal plate on the floor. He turned to a coworker and asked him to wiggle the raceway with the 3-ton overhead crane. Employee #1 stood up and stepped back as the coworker pushed the UP button to the overhead crane. The chain they were using to move the raceway broke, sending the rigging (block and hook) upward. When the rigging came down, it struck Employee #1 on top of the head. He fell backward and struck his head on the concrete floor. Coworkers came to his aid and contacted emergency help. Employee #1 was transported to Sacred Heart Hospital and admitted for a fracture to the skull.
