现代科学分析证明,火灾发生后,大量物质燃烧后主要产生一氧化碳、二氧化碳、二氧化硫、氮氧化物及少量的氮化氢气体等.这些气体高浓度时,不仅能直接伤害人的肌体,还因浓度太高造成局部区域氧气含量下降而使人窒息死亡,然而,上述气体对人员的伤害均有一个过程,不含在短时间内造成人员死亡.但近年来国外有关专家发现,在一些火灾死难者中,大多数人往往在极短时间内就昏死过去,根本来不及抢救,无法用一氧化碳等有害气体中毒来解释清楚.在一些居民住宅火灾案例中,消防人员在几分钟内就赶到现场投入扑救,在起火的住宅内抢救出来的竟都是
Modern scientific analysis shows that after the fire broke out, a large amount of material burned mainly produces carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides and a small amount of hydrogen nitride gas, etc. The high concentration of these gases not only directly injures the human body, but also because of the concentration However, the above-mentioned gas has a process of human injury, which does not cause death in a short time, but in recent years, foreign experts found that in some of the victims of fire , Most of them are often fainted in a very short period of time, simply could not rescue, can not be explained by the poisonous gas such as carbon monoxide poisoning.In some residential fire cases, firefighters rushed to the scene in a few minutes Save the fire, rescued in the fire in the house are actually
