冷库及地下工程(如利用人防工程改建的商场、旅社、工厂、餐厅等)发生的火灾,由于其出入口少,且仅有有限的几个孔与大气相通,故可统称为大型封闭空间内的火灾。 由于这类建筑物坚固,层次较多,内部空间大,门窗少,氨及燃烧生成气体有毒有爆炸危险且不易排除。常规的水、干粉等灭火手段往往难以凑效。在遇难人员脱险后,快而有效的灭火方法是——惰气灭火。

Fires in cold storage and underground works (such as shopping malls, hotels, factories, restaurants, etc. rebuilt by using civil air defense works) are collectively referred to as large-scale enclosed spaces because of their small number of entrances and exits and their limited number of holes communicating with the atmosphere Fire. Due to the sturdiness of these buildings, more levels, large internal space, less doors and windows, ammonia and combustion gases are dangerously toxic and can not be ruled out easily. Conventional water, dry powder and other means of fighting fire often difficult to work together. A quick and effective method of extinguishing fire after expelling a victim is - Inert gas fire extinguishing.
