Abstract: On January 25, 2010, Employee #1, a truck driver, delivered a heavy steel pipe, used in the fire sprinkler systems and he was preparing a loading strap. A coworker was loading packs of steel pipe, weighing approximately 2000 lb. The coworker inadvertently knocked a loaded pack of pipes on the other side of the bed of the truck, a Chevrolet C7500 flat bed. The steel fell 5 ft to the ground and struck Employee #1 on the shoulder, ribs and leg. Walking around the truck, the coworker discovered Employee #1 lying on the ground with a severe back pain and with his right leg caught under the steel pipes. The coworker immediately ran back, got the forklift, and removed the pack of steel pipe from Employee #1's leg. Paramedics transported Employee #1 to a hospital, where he died from internal injuries.
