最近,我们施工队的一位工人师傅在下阀门井去开给水阀门时,进入井内不到一分钟,就发生有些昏厥现象。由于上井快没有出现危险。经研究分析,我们认为,主要是由于有机物腐败发生二氧化碳造成。此种气体重于空气,不易逸散,常积于井底或山洞中。应注意防止这种过量气体对人的危害。 Recently, a worker master of our construction team came into the well in less than a minute when the next valve well opened the water supply valve and some fainting occurred. As there is no danger of getting on the well. The research and analysis, we believe, mainly due to the occurrence of carbon dioxide caused by organic matter corruption. This kind of gas is heavier than the air, easy to escape, often plot in the bottom or cave. Care should be taken to prevent the harm of such excess gases to humans.
