On March 9, 1998, a 38-year-old temporary laborer (the victim) was run over and crushed by an off-road dump truck while he was working at a santiary landfill. The victim had been assigned to pick up litter which fell from refuse collection vehicles traveling the landfill access road. He performed this task for about 2 1/2 hours and was then assigned to act as a traffic guide, directing trucks to the proper dumping location along the landfill working face. Approximately 45 minutes after the victim began this assignment, co-workers noticed he was no longer in visual or audible contact with them and began a search. A loader operator saw the victim lying near a stockpile of cover-dirt and notified the foreman, who contacted the local emergency services. A local rescue squad, sheriff's department, and the coroner responded. The victim was pronounced dead at the scene. NIOSH investigators concluded that, to prevent similar incidents, employers should: Ensure that workers follow procedures that minimize or eliminate pedestrian exposure to hazards from moving vehicles and mobile equipment. Consider the use of electronic signaling devices or sensors to warn equipment operators of the presence of pedestrians in the blind spots of mobile equipment. Ensure that routes of pedestrian travel are located to minimize worker exposure to hazards of vehicle movement during access and egress from rest rooms and similar facilities.
