The injured employee was changing a coil on a coil threader. As the employee walked toward the machine, his right leg contacted a compressed air line that was mounted to the side of the machine, causing him to fall toward drive rollers on the flex line coil threader. As he fell, his right hand entered the machine's point of operation. The employee suffered injuries that required the surgical amputation of the right index finger and ring finger, and a partial amputation of the right middle finger.
