During the fall of 2002, a 31- year-old man was killed when a skid-steer loader backed into a dump truck, pinning him between the dump truck and the skid-steer loader. The man was part of a construction crew preparing to pour a concrete foundation for a residential garage in a neighborhood. One man was operating a skid-steer loader, leveling the ground when another employee just arrived in a dump truck with a fresh load of gravel. Two other younger employees, one of whom was the victim, were locking down the tailgate so the truck could dump gravel on the ground. The operator of the skid-steer loader was not aware the dump truck had returned, and continued working with the loader facing in the opposite direction. At one point, the skid steer backed up to get another load of gravel. While working with the tailgate of the truck, with his back to the loader, the victim was struck from behind by the skid steer loader, and was crushed between the back of the loader and the back of the dump truck. The man staggered a bit, then dropped to the ground. He quickly became unresponsive and died shortly after from severe internal injuries. His co-worker was uninjured. The operator of the skid-steer loader was not initially aware of striking the man, for he did not make contact with the truck while backing up. Recommendations based on our investigation are as follows: 1. Employee safety training and education must be an integral component of every business mission, regardless of size or number of employees. 2. Employers must insure that employees are aware of hazards, limitations, or potentially dangerous conditions associated with using specific equipment on the jobsite. 3. Backup alarms with variable intensity and frequency should be installed on all skid-steer loaders, and owner/operators should ensure that mufflers are working properly to reduce machine noise.
