造成火灾中人员伤亡的主要原因是有毒烟气 ,开展对火灾烟气毒性的研究具有重要的意义。气体毒性研究的主要目的是为了评价各种建筑材料在火灾条件下的毒性 ,长期以来在如何评估火灾烟气的潜在危害和如何用实验方法得到精确数据方面一直存在争论。本文重点探讨国际上在该领域中常见的一些毒性评估和实验方法 The main cause of fire casualties is toxic fumes, to carry out research on fire smoke toxicity is of great significance. The main purpose of the gas toxicity study is to evaluate the toxicity of various building materials under fire conditions. There has been a long debate over how to evaluate the potential hazards of fire smoke and how to obtain accurate data experimentally. This article focuses on some of the most common international methods of toxicity assessment and experimentation in this area
