一、前言 火灾时伴有大量浓烟。由于烟阻碍视力,包含毒性和对人精神上造成威胁,所以火灾中的死亡者中相当一部分并非死于火,而是死于烟。目前我国的建筑材料和家具材料已开始采用塑料和各种合成材料,这种状况大体上与西方六十年代相同。塑料和各种合成材料在火灾时迅速产生大量毒性很强的浓烟,是造成火灾致命的主要原因之一。现在西方国家住宅火灾中死亡者一半以上死于烟。表1中给出了英国六十年代初到七十年代初的火灾致命原因的统计资料。
First, the foreword accompanied by a large number of smoke in the fire. Since smoke blocks vision, contains toxicity and poses a threat to the human spirit, a significant proportion of those who died in the fire did not die of fire but died of smoke. At present, China’s construction materials and furniture materials have begun to use plastic and various synthetic materials, this situation is generally the same with the Western sixties. Plastic and all kinds of synthetic materials in the fire quickly produce a large number of highly toxic smoke, is one of the main causes of fire fatal. More than half of all deaths in residential fires in western countries have now drowned. Table 1 shows the statistics of the fatal causes of fires in the United Kingdom from the early 1960s to the early 1970s.
