氯乙烯CH2=CHCl气体测毒管132SC VINYL CHLORIDE 0.1-12.0ppm

简要描述:

氯乙烯CH2=CHCl气体测毒管132SC VINYL CHLORIDE 0.1-12.0ppm,应急处理: 迅速撤离泄漏污染区人员至上风处,并进行隔离,严格限制出入。切断火源。建议应急处理人员戴自给正压式呼吸器,穿防静电工作服。尽可能切断泄漏源。用工业覆盖层或吸附/ 吸收剂盖住泄漏点附近的下水道等地方,防止气体进入。合理通风,加速扩散。喷雾状水稀释、溶解。构筑围堤或挖坑收容产生的大量废水。如有可能,将残余气或漏出气用排风机送至水洗塔或与塔相连的通风橱内。漏气容器要妥善处理,修复、检验后再用。
