Avulsions, enucleations

The wiring for an argon oxygen decarburization (AOD) motor caught fire and the AOD had to be operated manually. An employee attempted to insert a crank handle into the AOD crank. As the employee was manually tilting the AOD, it moved beyond the center of gravity and the crank handle started spinning rapidly. When the employee tried to grab the crank handle, his right middle finger was caught in the chain and sprocket, de-gloving the fingertip. The chain and sprocket was unguarded at the time of the incident.
