Abstract: Employee #1 was threading a wire draw machine. A steel chain was used to pull the wire from the draw box onto the revolving drum that collected the newly sized wire. The company allowed the machine to be operated when they knew that the micro-switch for the door enclosure which was part of the interlock system was broken. Employee #1's arm was pulled into and between the revolving drum and a tension wheel by a chain that was used to connect the wire to the revolving take up drum that was collecting the newly sized wire. Employee #1 suffered a broken right forearm and the amputation of a section of his right middle finger that was pinched off as it was caught between the wire and the hub of the drum. Employee #1 was hospitalized.
