• Description:
  A 22-year-old male maintenance machinist trainee (the victim) died after becoming entangled in a rotating shaft of a vertical boring mill. He was drilling holes in the concrete perimeter walls of a 32 inch deep machine pit that contained the boring machine. A 2 1/2 inch diameter shaft extended vertically 9 feet from a baseplate on the floor of the pit to the upper portion of the machine. The shaft was unguarded and centrally located 16 inches from the machine edge, and 16 inches from the pit wall, and was rotating at a rate of 3-4 rotations a minute. The victim was apparently positioned adjacent to the shaft when the sleeve of his jacket was caught and pulled by the shaft and he was whirled around the shaft and his head struck the machine edge. A co-worker heard the victim yell, turned in his direction, and saw him caught on the shaft. The co-worker ran to the control panel, hit the emergency stop button, and went to his office to call 911. Another co-worker ran to the victim's aid and attempted to suspend his body until rescue workers arrived. He was transported to the emergency room, where he was pronounced dead. The FACE investigator concluded that, to prevent similar occurrences, employers should: 1. Enclose/guard mechanical power-transmission equipment (e.g., vertical drive shafts), where the potential exists for an employee to become entangled or caught in the equipment. 2. Develop, implement and enforce a written safety program which includes, but is not limited to, worker training in hazard identification, avoidance and abatement. 3. Designate a competent person to conduct regular safety inspections.
