Abrasions, scratches

An employee was loading empty carts into a semi-trailer using the lift gate mounted on the rear of the trailer. While he was riding the lift gate up and demonstrating this process to a trainee, he tried to reposition his feet, shifting from one foot to the other. In doing so, he stepped over the lip at the side of the lift gate. His foot then hooked onto one of the bars that allows the lift gate to travel up and down and his leg became caught, causing a scrape and swelling to the calf. He was hospitalized.
