不久前,在我市某化工厂发生一起急性氮气合并氯乙烯气体泄漏中毒事故,死亡工人两名。气体泄漏在地平面下一个4×4×2m~3的空间内。一名工人下去工作后已经死亡,当班工人发现后立即组织抢救,一名工人戴着过滤式防毒面具下去救人,岂不知,当时在泄漏气体的空间内已成为高度低氧环境,所戴的防毒面具在下面不能发挥供氧的作用,结果,在抢救过程中又造成这名工人死亡。我们在事故现场询问抢救人员有关防毒面具方面滤料成份、滤毒罐的标色可预防哪些有害物质、防毒面具的使用条件等基本知识,工人知之甚少。 Not long ago, in a chemical plant in our city, an acute nitrogen gas poisoning accidental leakage of chlorine gas occurred and two workers died. Gas leakage in the ground plane under a 4 × 4 × 2m ~ 3 space. A worker who died after going to work and immediately after the workers on duty were found to be rescued and rescued. A worker wearing a filtered gas mask to save people did not know it. At that time, it had become a highly hypoxic environment in the space where the gas leaked. Gas masks below can not play the role of oxygen, as a result, in the rescue process caused the death of the worker. At the scene of the accident, we asked the rescuers about the basic knowledge of the filter ingredients in gas masks, the color of the canister to prevent any hazardous substances and the conditions of use of the gas masks, and little is known to the workers.
