Abstract: Employee #1, a delivery truck driver with three months experience on the job, was using a pallet jack to off-load palletized books at a customer's location. He was backing the loaded pallet jack out of the truck and onto the powered tailgate when the vehicle's batteries went dead and he had to apply more effort than normal. As Employee #1 reached the tailgate, he lost his balance and began to fall sideways off the gate. His foot became stuck under the pallet and he ended up falling on his head. Employee #1 was transported to the hospital, where he underwent surgery to treat his head injuries.
