During the fall of 1999, a 53-year-old construction worker was killed after he unloaded sand from a dump truck. He partially raised the box of his truck to dump out a portion of wet sand at a work location, then leaned under the box to manually trip the hydraulic linkage to bring the box down. The hydraulic linkage was located at the hydraulic pump, behind the cab between the main frames of the truck. This action was apparently a habit to save some time from walking around the truck to push the dump lever inside the truck cab. However, this time, because of the heavy load of sand, and because the box was only partially raised, the truck box came down immediately pinning the man between the box and the frame of the dump truck. The man suffered massive head injuries and was dead at the scene. The deceased truck driver had several years of experience with machinery and was the lead man for the small construction company. Recommendations based on our investigation are as follows: 1. Workers should use proper machine controls rather than actuating machine functions at hazardous locations. 2. Employers should train and supervise workers adequately to ensure that safe procedures are followed. 3. Manufacturers of dump trucks should consider options to discourage unsafe use of dump box hydraulics, such as placement or shielding of controls.
