Employee 1 was using a forklift to unload engines and transmissions from a truck. The forklift couldn't get to the engines into the back of the truck, so employee 2 moved the engines to the edge of the truck with a pallet jack. Employee 1 reached to grab the pallet while employee 2 pushed with the pallet jack. When the pallet hit the sheet metal strip of the truck, the engine shifted onto employee 1's finger, resulting in a partial amputation.
