On January 29, 2002, a 34-year-old roadway construction worker (the victim) was killed when he was backed over by a dump truck. The victim was walking along the side of a road grader picking-up centerline lane reflectors when a dump truck loaded with asphalt backed over him. When notified by CB radio that the paving machine was ready for him, the driver exited the staging area, entered the work zone and started backing-up towards the paving machine. As he backed, he reported that he did not see the victim and thought that the victim had moved out of the way. While backing, the dump truck operator said that he heard a voice over his CB radio yelling for him to stop because he had hit someone. Instead of stopping, the truck driver moved his truck forward approximately 20-feet, and again was told to stop because he had hit someone. Local Emergency Medical Services (EMS) responded within minutes. EMS determined that the victim was deceased and contacted the county coroner who pronounced the victim dead at the scene. NIOSH investigators concluded that, to help prevent similar incidents, employers should: 1. ensure that workers on foot remain clear of moving equipment by developing and utilizing an "Internal Traffic Control Plan" for each highway and road work project; 2. consider the use of electronic signaling devices or sensors to warn equipment operators of workers on foot in the immediate work area; 3. ensure that during planning phases of roadway construction projects, staging areas are planned so as to minimize backing distances through workzones; 4. consider the use of a spotter for assistance when backing trucks into a work zone; 5. ensure that all workers on site are trained to follow standard operating procedures for entry and exit in the workzone; and, 6. ensure that work is scheduled to allow for sufficient rest periods for workers.
