Abstract: On June 27, 2013, Employee #1 was milling an aluminum part on a Bridgeport Mill machine (Number 341). The machine was located in a fabrication-engineering workshop. While operating the machine, he used his right hand to crank its handle and his left hand to reach across and adjust a coolant spray hose. The hose sprayed out pressurized air in a radiant shape to cool the milling part. It had to be aimed at the milling point. As he moved the hose, his left middle fingertip accidentally contacted the milling part and was trapped between the work piece and the cutter, causing its amputation. Employee #1 was transported to a medical center, where he was received treatment and was then released.
