On September 6, 2003, a 75-year-old logger, working as a bulldozer operator, was killed when the D6H Caterpillar crawler tractor he was operating tumbled off a steep skid road into a ravine. The operator was climbing a 20-25 degree slope while reopening an old skid road. The bulldozer slid off of the road against a tree while on a hard rock face covered by a 4-inch surface of scrabble rock. The operator apparently regained control, and may have been trying to get the bulldozer back up on the road when it slipped off the 60-70 degree sidehill and tumbled about 150 ft to a logging road, where the operator was ejected. The bulldozer bounced another 450 ft into a ravine. The event was not witnessed. Fatal injuries probably occurred when the victim was thrown around in the cab, before being ejected. Recommendations: 1. Develop a site-specific safety plan that includes an assessment of hazards and plans to minimize the risks. 2. When operating off-road work machines, wear the seatbelt, or utilize some other form of personal safety restraint. 3. Seek assistance when needed. 4. Drop the blade to help control or stop a slide. 5. Manufacturers should evaluate operator restraint systems for mobile equipment to design improvements that facilitate use of seatbelts and harnesses.
