An employee was using a forklift to empty a trash bin into a larger trash container. He dismounted the forklift to open the trash bin's door. When he opened the door, the release of the trash made the bin bounce on the forklift forks. His hand was on one of the forks when the bin moved, and his left index fingertip was crushed between the bin and the fork. His fingertip had to be amputated.
