An employee was cleaning a scalder. He laid the nozzle end of his water hose over the side of the scalder while he left to perform another task. When he returned to pick it up and lifted it, the hose became entangled in the running shackle line. As he tried to pull the hose out, his left middle finger was caught on the handle of the water valve nozzle attached to the hose. He pulled his finger back as the line was moving, sustaining a finger avulsion that required surgical amputation.
