Abstract: Employee #1 was working in the tank house on the #1 trimmer machine. Copper starter sheets are fed into the machine, which squares them up. During the squaring up process, strips that are cut off the sides of the sheet drop down a chute into the chopper, where they are chopped into small pieces and then dropped into a bin. Frequently, the strips become hung up in the chute and need to be either pushed down through the chute or pulled back up out of the chute. A push stick is used to push the strips down; pulling the strips out is done by hand. Employee #1 needed to pull some strips out of the chute. While the machine was running, he cleared the chute and was removing his hand from the machine when his glove became caught by the chain and sprocket that was driving the feed roller. His fingers were pulled into the nip points and three of them were amputated.
