Abstract: On May 10, 2006, Employee #1, a truck driver, was located at a holding storage space for recyclables to pick up recycled materials. The employer is part of a recycling process, where one trucking company offloads recyclables to the holding storage space, while Employee #1's company picks them up for disposal. Employee #1 was standing in the entryway to the recyclable drop off area, which was covered with debris. A bobcat driver was shoveling the recyclables onto a conveyor that sends the recyclables through a chute and into parked trailer trucks for disposal. As Employee #1 was watching this process, a truck entered the drop off area for a delivery. Employee #1 was killed. The accident investigation measured the noise levels in the drop off area to measure between 84 to 98 dBA with the back-up alarm of the drop off truck, that struck Employee #1, measuring between 75 to 80 dBA. Although the back-up alarm was used at the time of the accident, it was unlikely that Employee #1 would have heard it in time to move from the danger area.
