On July 22, 2005, a 56-year-old machine operator (the victim) died after he was struck by a flying guard from a wood chipper. The victim was working alone when he shut down the chipper. The chipper was a machine used to reduce wood edging and other wood waste into wood chips. The victim shut down the chipper and the blade continued to rotate for up to thirty minutes. The victim was found by one of the sawmill partners at approximately 6:00 p.m. The partner notified Emergency Medical Services (EMS) at 6:11 p.m. They arrived at 6:17 p.m. The EMS took the victim to the hospital located 20 to 25 miles away, at 6:23 p.m. The local EMS requested a paramedic intercept with a larger, better trained and more experienced crew. The EMS arrived at the hospital at 6:46 p.m. A doctor in the hospital declared the victim dead at 6:57 p.m. The FACE investigator concluded that to help prevent similar occurrences, employers should: 1. ensure that guards are properly replaced or repaired; 2. ensure that rotating machine blades are stopped and hazardous energy is dissipated before blade removal begins; 3. ensure that workers are trained to recognize the hazards associated with working near or around rotating chipper blades; 4. implement an effective Lockout Tagout program that at a minimum, meets standards set by the Occupational Safety and Health Administration (OSHA) in General Industry Regulation 29 CFR 1910.147.
