Crushing injuries

An employee had loaded several 6-foot by 6-inch guardrail posts onto the lift gate of a truck with a covered bed on the back. The employee was riding on the lift gate as the truck was driven at about 5-mph to an installation site 100 yards away. When the truck turned onto a median to change directions, one of the posts slid towards the ground and became caught between the ground and the bracketing. The employee's left leg was pinned between the post and the truck bed, causing crushing injuries and lacerations to the lower leg. The employee was hospitalized.
