Incident on Jan 12, 2004: Employee amputates fingers while operating punch press
On January 12, 2004, Employee #1, a punch press operator, was working in the met al fabrication department of a glass door manufacturing facility. His supervisor instructed him to perform a lockplate operation, which involves placing three s mall components together. Once the components are placed into the die mold, the punch press comes down and mashes the rivet shaft which keeps the pieces togethe r. The 22-ton partial revolution punch press, manufactured by Bliss, Model Numbe r C-22, experienced a problem with its light curtain a few months earlier, which required the employer to install a new light curtain with a controller box. Fol lowing the repair, the employer tested the machines performance and it was deter mined operational. Additionally, while performing the lockplate operation, the l ight curtain was functioning properly. The punch press is always operated by a p ress pedal. If the foot pedal is not depressed and the operator's his hand enter s the light curtain, the press will stop. If the operator depresses the foot ped al while his hand is breaking the light curtain, the press will not cycle. Howev er, if the employee continually depresses the foot pedal, and places his hand th rough the light curtain, the press will cycle itself, depending on the location of the ram. There is no anti-repeat function. For some reason, a malfunction occ urred and Employee #1's right hand came into contact with the press. He received lacerations on his right index and middle fingers, as well as loss of bone on h is middle finger. Employee #1 was hospitalized and treated for his injures, whic h required partial amputation of his right middle and index fingers. Employee #1 was experienced and knowledgeable in the proper operating procedures having ope rated the press for 7 years. An investigation determined the employer could have prevented the accident by implementing a more effective energy control procedur e, properly identifying the function of all control buttons and switches on the power operated presses, color code all control buttons and to conform to the cod e, and instating tonnage and stroke requirements. Also, the control system was n ot constructed so that a failure within the system would not prevent the normal stopping action from being applied to the press when required, but does prevent initiation of a successive stroke until the failure is corrected.
