Abstract: An employee was working on a Blue Valley Circle Shear, Model number 65B, Serial number 102, which had a 0.375 in. capacity. He was positioned on the out-feed side of the machine and another employee, who is a machine operator and his supervisor, was standing on the other side of the shear. He was manually flexing a 10-gauge sheet of stainless steel when it broke free from the sheared sheet stock. This piece struck the employee on his lower left arm near his wrist causing a deep laceration that severed muscles and nerves. He was not trained on this particular machine or assignment and was not wearing protective clothing for this operation. The employee was hospitalized.
