Amputations, avulsions, enucleations unspecified

An employee was loading components into fixtures on an automated CNC Line. He was moving a J-Hook lifting apparatus by hand from its storage location to the raw material area in order to pick up a piece of steel. The employee had the crane remote and the neck of the J-Hook apparatus in his right hand. When he went to set the J-Hook down on the floor, he placed his left middle finger inside of the lifting loop of the magnet. As he manually lowered the J-Hook to the floor by the neck, it fell. As the neck dropped to the floor, the magnet shifted and the lifting loop of the magnet retracted into the bracket of the J-Hook, fracturing and amputating the fingertip.
