On February 24, 1995 a 27 year old worker for an agricultural maintenance company was killed while repairing a silo bottom unloading auger. The victim was working inside a cement silo filled with corn silage, repairing a sweep auger that was damaged due to frozen feed inside the silo. The worker was lying inside on the floor of the silo behind the auger safety shield when he shouted that he was clear of the auger. A workmate outside at the electric control panel turned on the auger for approximately 15 seconds to dislodge frozen corn silage in the auger. During that time the victim apparently reached to move a trouble light hanging near the auger, and got caught in the moving auger knives, severing his arm and shoulder, and causing severe chest injury. He was taken to a local hospital and pronounced dead on arrival in the emergency room. Recommendations following our investigation were as follows: 1. Employers should develop, implement, and enforce a comprehensive written safety program. 2. Employers installing, servicing and repairing silo equipment should provide employee training and proper equipment for confined space entry. 3. Employers and workers should develop a procedure to prevent intentional and unintentional operation of the silo unloading mechanism when a worker is inside a silo or in close proximity to the unloading augers.
