Electrician run over by 170 ton truck in Wyoming.
NIOSH 1994 Mar; :1-3
A 49 year old male died from injuries suffered when the pickup in which he was sitting was rolled over by a 170 ton haulage truck that rolled from a parked position on a muddy 8% grade ramp. The victim was repairing an electrical defect to the propulsion system of the hauler, and had backed his pickup up a muddy ramp with an 8.3% grade to the rear underside of the hauler to use as a platform to enter the rear axle box housing opening. This opening is 2 feet square and sits 51" from ground level. The operator of the hauler had applied both the dump and park brake systems, and had installed chocks behind two of the rear wheels. The hauler's brake system failed while the victim was sitting in the cab of his pickup, and the hauler rolled down the incline, overrunning and crushing the pickup and continuing on down the incline and striking the face of a highwall some 160' past the original position of the hauler. Employers may be able to minimize the potential for occurrence of this type of incident through the following precautions: 1. Insure that employees take extra precautions when weather affects otherwise safe activities. 2. Instruct employees in the hazards of using vehicles as a platform for performing activities. 3. Review preventive maintenance procedures to determine if they are adequate for best practical safety practices.
