室内常用装潢材料火灾烟气毒性危险级别研究

Research on Smoke Toxicity Dangerous Level of Commonly Used Decorative Materials

火灾烟气是火灾中人员致死的主要原因之一,随着室内装饰材料的广泛应用,室内装饰材料的燃烧烟气毒性越来越受到人们关注。研究装饰材料的燃烧烟气毒性,确定产烟毒性危险级别,可以为合理选用装饰材料提供参考。室内的各种装饰材料燃烧会产生各种气体,因材料不同,产生气体成份复杂,无法用单一的气体指标来衡量。本文使用动物染毒法对选定的典型装饰材料进行产烟毒性分级,对选用装饰材料具有一定的参考意义。

Smoke in the fire is one of the main causes of death. With the wide application of decorative materials, more and more attention is paid on smoke toxicity of decorative materials. Studying smoke toxicity of decorative materials and determining its toxicity level provides a reference to selecting decorative materials. Decorative material combustion produces a variety of gases, due to the difference of materials, the gas composition is complex, and can＇t be measured by single index. In the study, method of animal contaminated was used to study smoke toxicity level for typical decorative materials. The results had certain reference significance for decorative materials selection.
