From 1980-1989, Alaskan workers died at a rate approximately five times the U.S. national rate, due in large part to accidents in the commercial fishing industry. In response to this problem, in 1991, the National Institute for Occupational Safety and Health (NIOSH) established the Alaska Field Station (AFS) in Anchorage, Alaska. A principal goal of AFS is to gather and analyze fishing fatality and injury data and make recommendations for research to address problem areas. One area that AFS staff identified was hazards related to deck machinery, specifically the capstan winches typically found on purse seine fishing vessels. For example, fishermen can become entangled in the ropes and can't shut-off the winches. In 2004, Spokane Research Laboratory (SRL) of NIOSH, in collaboration with AFS, began development of an engineering intervention to improve safety for such a winch. SRL staff met with vessel owners, seine fishermen, and winch manufacturers to discuss various design options. The final design, an emergency-stop (e-stop) system, incorporates a momentary contact switch mounted directly on the winch and an adjunct electro-hydraulic control circuitry. The prototype e-stop system was installed on an operating purse seine vessel and tested successfully during the summer 2005 fishing season in Alaska. The system is currently being refined in preparation for additional testing in 2006. This presentation discusses the basis for research into deck machinery safety, engineering intervention options, details of the SRL e-stop system as installed, initial results of field tests, and recommendations for additional development.
