宁晋县队办仪表厂是从1971年1月开始兴办的,相继在3个公社6个大队办起15个厂。汞作业危害是常见的职业中毒,于1975年8~10月先后发生几名汞中毒患者。汞,俗称水银,白色,易流动,是一种在常温下唯一的液体金属。比重13.6,熔点-39℃,沸点356.9℃。在常温下即能蒸发,温度越高,蒸发越快。在低温时,也有少量的蒸发。防止汞蒸汽向空气中逸散,是预防汞中毒的一个重要环节。金属汞溅洒在地面或工作台形成许多细小水银珠,可增加蒸发的表面积,加速蒸发。汞污染作业场所后,可被地面、墙壁缝隙、桌椅工具、衣物和头发吸附,是形成汞的多种污染源和持续污染的主要因素。金属
Ning Jinxian team to do the dashboard factory was established from January 1971 to start, one after another in 6 communes six brigades set up 15 plants. Mercury job hazards are common occupational poisoning, from August to October 1975, there have been several cases of mercury poisoning. Mercury, commonly known as mercury, white, easy to flow, is a liquid metal at room temperature only. The proportion of 13.6, melting point -39 ℃, the boiling point of 356.9 ℃. At room temperature that is able to evaporate, the higher the temperature, the faster the evaporation. At low temperatures, there is also a small amount of evaporation. Preventing mercury vapor from escaping into the air is an important part of preventing mercury poisoning. Metal splashes sprinkle on the ground or workbench to form many tiny mercury beads that increase the surface area for evaporation and accelerate evaporation. Mercury contaminated workplaces can be adsorbed by the ground, gaps in the walls, table and chair tools, clothing and hair and are the major contributors to various sources of mercury and persistent contamination. metal
