一．洗眼器的定义

   洗眼器：当发生有毒有害物质（如化学液体等）喷溅到工作人员身体、脸、眼或发生火灾引起工作人员衣物着火时，采用的一种迅速将危害降到的有效的安全防护用品。
   不过，洗眼器产品只是用于紧急情况下，暂时减缓有害物对身体的进一步侵害，进一步的处理和治疗需要遵从医生的指导。
   洗眼器早在80年代就在国外发达工业国家（美国、英国等等）的绝大多数工厂、实验室和医院广泛采用。其目的用于减少遭受在工作中有毒有害物对身体的伤害，广泛应用于石油、化工、半导体工业、医药制造业和有危险物品暴露的场所。

二。洗眼器执行的标准

在中国洗眼器没有具体的法规，目前洗眼器执行的标准有两个:目前洗眼器有二个标准：一个是美国洗眼器标准ANSI Z358.1-2004，一个是欧洲洗眼器标准DIN-12899。目前国内很多洗眼器生产企业一般都采用美国洗眼器标准。
洗眼器在中国的发展有数年的历史了,生产洗眼器的厂家有20多家,但是在中国还没有洗眼器的相关标准,生产厂家一般参照美国ANSI Z358-1 2004洗眼器标准.
