A 28-year-old male owner of an excavation company (victim) was fatally injured after the bulldozer he was operating slipped over the side of a flat bed trailer. The injury occurred as a result of the victim striking his head on the bulldozer's rollover protective structure (ROPS). The seat belt in the bulldozer had been removed; the victim was not restrained in the bulldozer. At the time of the incident the trailer sat across (blocking) a 7 percent inclined roadway. As the victim backed the bulldozer toward the rear of the trailer, its metal track cleats slipped on the metal surfaced portion of the trailer over the wheels down grade toward the trailer's edge. The bulldozer slipped off the edge and overturned onto its left side. The victim struck his head on the ROPS as he attempted to jump clear. He died of the injuries he received. MN FACE investigators concluded that, in order to prevent similar occurrences, the following guidelines should be followed: 1. trailers should be level and stable before unloading equipment to prevent slippage of the equipment off trailer edges; 2. seat belts should be provided for earth moving or other types of mobile construction ;equipment; and 3. operators should be restrained with seat belts when using construction equipment to avoid the hazards of being thrown from, or injury within, it.
