冷库火灾扑救中的极端火现象研究

Study on Extreme Fire Phenomenon in Cold Storage Fire Fighting

冷库火灾受建筑结构和保温材料的影响,极易发生轰燃、回燃、爆炸和快速火等极端火现象,这四类极端火现象是导致冷库火灾失控的主要原因,易造成严重的财产损失和人员伤亡。消防救援队伍在扑救冷库火灾时,应根据建筑结构特点和火灾发展规律,综合运用惰化窒息灭火策略、空地结合侦查灭火策略、正压式排烟灭火策略和水炮外攻灭火策略等,破坏极端火发生的条件,快速有效地扑灭冷库火灾。

Due to the influence of building structure and insulation materials,cold storage fires are prone to extreme fire phenomena such as flashover,backdraft,explosion and rapid fire,which are the main causes of uncontrolled cold storage fires,resulting in serious property losses and casualties.According to the characteristics of the building structure and the law of fire development,the fire fighting and rescue team should comprehensively use the inerting and suffocating fire extinguishing strategy,the air-ground combined investigation fire extinguishing strategy,the positive pressure smoke exhaust fire extinguishing strategy and the water cannon external attack fire fighting strategy to destroy the conditions of extreme fire and quickly and effectively extinguish the cold storage fire.
