The majority (67%) of hospitalized injuries among Alaska commercial fishermen are associated with deck machinery. This paper describes the "Prevention Through Design" process to mitigate one serious machinery entanglement hazard posed by a capstan deck winch.
After observing that the capstan winch provides no entanglement protection and the hydraulic controls are usually out of reach of the entangled person, NIOSH personnel met with fishermen and winch manufacturers to discuss various design solutions to mitigate these hazards.
An emergency-stop ("e-stop") system was developed that incorporated a momentary contact button that when pushed, switches a safety-relay that de-energizes the solenoid of an electro-hydraulic valve stopping the rotating winch. The vessel owners that had the e-stop installed enthusiastically recommend it to other fishermen. NIOSH entered into a Proprietary Technology Licensing Agreement with a company to develop the system for commercial use.
This is an example of a practical engineering control that effectively protects workers from a hazardous piece of equipment by preventing injuries due to entanglement. This solution could reduce these types of debilitating injuries and fatalities in this industry.
阿拉斯加商业渔民住院受伤事件中，大部分（67%）与甲板机械有关。本文描述了“通过设计进行预防”的过程，以减轻绞盘式甲板绞车带来的一种严重机械缠绕危险。
在观察到绞盘式绞车没有防缠绕保护且液压控制装置通常在被缠绕者够不着的地方后，美国国家职业安全与健康研究所（NIOSH）人员与渔民和绞车制造商会面，讨论减轻这些危险的各种设计解决方案。
开发了一种紧急停止（“急停”）系统，该系统包含一个瞬时接触按钮，按下该按钮时，会切换一个安全继电器，使电动液压阀的螺线管断电，从而停止旋转的绞车。安装了急停系统的船主热情地向其他渔民推荐该系统。NIOSH与一家公司签订了专有技术许可协议，以开发该系统用于商业用途。
这是一个实际工程控制的例子，通过防止因缠绕导致的伤害，有效地保护工人免受危险设备的伤害。这种解决方案可以减少该行业此类使人衰弱的伤害和死亡。
