A worker was run over and killed on a busy worksite when a dump truck and trailer backed over him. Several factors contributed to this fatal accident. The truck was backing up without guidance from a traffic control person. The victim had his vision obstructed by a hooded rain jacket, and he was talking on a cellular phone. The noise level on the site was very high at the time of the accident.

Safe work practices:

• Develop safe work procedures based on hazards specific to the worksite, and make sure they are enforced.
• Ensure that workers receive orientation to the worksite and are trained and supervised in site-specific safe work procedures.
• Ensure that mobile equipment operators are directed by a worker with an unobstructed view of the area that the vehicle is backing into.
• Establish procedures for use of cellular phones in high-hazard areas.
