Factors Reported in Amputation and Other Injury Cases at Mechanical Power Presses between 1976 and 1984.
Trends in Ergonomics/Human Factors V, Proceedings of the Annual International Industrial Ergonomics and Safety Conference, New Orleans, Louisiana, June 8-10, 1988 1988:629-638
A discussion was presented on injury factor analysis using a NIOSH computerized data base of information on reports submitted to OSHA between 1976 and 1984 concerning amputations and other worker injuries occurring at mechanical power presses. The analysis included the effectiveness of two hand devices as a safeguard, production status at occurrence of injury, feeding method, type of safeguard, and means of actuating the press stroke. In the 652 injury cases in which a two hand device was used as a safeguard, repeat of press and failure of press ranked first and second, respectively, at 25 and 17 percent; in another 17 percent of theses injury cases said safeguard was not used. Use of a two hand device grew from slightly over 20 to over 40 percent of injury cases from 1976 to 1984. Injury during normal operation was much more common, 86 percent, than during setup, 14 percent. There were about as many injuries with the hands in die (HID) as with the no hands in die feeding method. The injury trend increased slightly when HID was the feeding method. In the 2184 cases of normal operation injuries, the use of two hand devices and fixed guards ranked first and second, respectively, at 29 and 25 percent. In 1495 normal operation injury cases with foot control actuation, the three leading safeguards were fixed guard, pullout/restraint, and no safeguard, at 33, 29, and 17 percent, respectively.
