  其次,在七氟丙烷灭火时的热分解毒性上,必须说明的是:所有火灾都会产生有毒和腐蚀性燃烧产物,其浓度受燃烧物的特性、系统动作时的火灾大小、探测系统的灵敏度与探测器的间距、为人员疏散所设计的延时时间、灭火剂的喷射时间、火灾增长速率、防护区容积及灭火剂的设计浓度等许多因素影响。七氟丙烷在高温下进行分解所产生的分解物可能具有的危害性,这种分解物主要是灭火剂中的氟,在有氢元素存在的情况下会产生具有辛辣气味的氟化氢(HF)。氟化氢能给人体带来不适和伤害。但国外有关试验证明,只要七氟丙烷的喷射时间和灭火时间能按要求得到控制,灭火过程中只有少量七氟丙烷分解并形成氢氟酸(HF)。在正常通风情况下,对人体的伤害是微乎其微的。 所以你是不用担心七氟丙烷毒性的,七氟丙烷是否有毒这个要看设计浓度,如果是指七氟丙烷灭火剂hfc227ea的话是高于10%浓度是低毒,但是我国的七氟丙烷气体灭火在设备生产的时候浓度已经控制在10%以内的了,所以你能在市面上看到的七氟丙烷灭火设备都是无毒的了,七氟丙烷中毒了怎么办,理论上是不会发生七氟丙烷中毒的,因为所有七氟丙烷灭火设备设计的时候浓度已经控制在无毒范围内了。
