An employee was working on a portable stainless-steel vessel equipped with a butterfly valve at the bottom. The employee used a crane to raise the vessel and connected an airline to the valve control. Upon activating the compressed air supply, the valve opened. While holding the bottom of the vessel with their left hand, the airline disconnected and the valve closed on their left index fingertip. The employee sustained an avulsion of the fingernail, an open nondisplaced fracture of the distal phalanx, and partial amputation of the fingertip.
