An employee was working with a driver who was backing a box truck into the garage of a newly built home to unload construction materials. He was standing behind the truck guiding the driver towards the garage. The ramp had been pulled approximately 8 feet out of the back of the box truck at the time. As the driver was attempting to position the truck, the employee was pinned between the ramp and the inside door jam of the garage door, fracturing his upper leg. He was hospitalized.
