洛阳东都商厦发生火灾,309人丧生,据法医鉴定,这些遇难者全部为呼吸道灼伤窒息死亡。1993年4月,唐山林西百货大楼发生火灾,79人丧生,这些遇难者除1人系跳楼高空坠落死亡外,其余均为一氧化碳及其他毒气窒息死亡后被焚烧……大量的火灾案例表明:火灾中人员伤亡80%以上不是直接与燃烧物接触所致,而主要是由于窒息或吸入有毒烟雾致死,烟雾可以说是火灾第一杀手,因此,如何防烟是发生火灾时逃生自救的关键。 A fire broke out in Luoyang East Commercial Building, killing 309 people. According to forensic identification, all these victims died of respiratory suffocation asphyxiation. In April 1993, a fire broke out in Linxi Department Store in Tangshan, leaving 79 people dead. All but one of these victims were killed and injured when they crashed into the sky. All the others were carbon monoxide and other poisonous gases that were suffocated and died after being burned ...... A large number of fire cases showed that: More than 80% of the casualties in the fire are not caused by direct contact with the burning materials, but mainly due to asphyxiation or inhalation of toxic fumes, which can be said to be the first killer of fires. Therefore, how to prevent smoking is the key to escape from fire in the event of a fire.
