化学品事故应急响应中危害距离的确定

Determination of hazard distance in the chemicals accidents emergency

介绍了不同国家、机构确定的毒性物质、易燃易爆物质紧急暴露限值和化学品事故中危害距离的确定方法,并以液氯钢瓶泄漏事故说明毒性危害距离的确定,以天然气管线泄漏火灾、爆炸事故说明火灾爆炸事故危害距离的确定。

This paper introduces the emergency exposure limits of toxic and flammable materials in different countries and institutes, and the method of determination hazard distance in the chemicals accidents emergency. It discusses the determination of toxic hazard distance with leakage accident of liquefied chlorine cylinder as example; the fire and explosion hazard distance with the leakage of natural gas pipeline as example.
