毒性是评价灭火剂的主要指标之一,特别是在封闭系统及有人场合的灭火,要求使用高效低毒的灭火剂。二十世纪初曾普遍使用四氯化碳(104),由于本体毒性及热分解产生剧毒光气,第二次世界大战中已停用。
Toxicity is one of the main indicators to evaluate fire extinguishing agents, especially in closed systems and in some occasions, and requires the use of highly effective and low toxicity fire extinguishing agents. CTC (104) was commonly used at the beginning of the twentieth century and was turned off during World War II due to the bulk toxicity and thermal decomposition of toxic carbon dioxide.
