Abstract: Employee #1 was standing in the center of a street diverting traffic to allow a caterpillar front-end loader to back up. This front - end loader has Model Number 920, vehicle Identification Number 76-920a, and Serial Number 62K3182. Employee # 2, the operator of the front-end loader, lost eye contact with Employee #1 as he backed up the front - end loader into the middle of the street. Employee #2 steered the front- end loader directly at Employee #1, running over him with the left wheel of the loader. Workers were in the process of unloading 8- inch pipes from a truck at the time of the incident. Employee #1 sustained multiple fractures of the pelvic bone. The front-end loader was equipped with a back-up warning device, but at the time of the incident, the warning device was not operating.
