An employee was using a double pallet jack to select product and palletize goods. She had selected a batch and was proceeding to drop off two pallets at the staging area. While reversing to line up the pallets she was pinned between the pallet jack and storage racking. Additionally, freight was knocked loose and fell from the rack. The employee had difficulty breathing and sustained swelling to both arms, a bruise on the left arm, and tension in the neck.
