近年来,油厍单罐面积越建越大,油库火灾爆炸发生的次数和损失与2000年以前相比急剧增长,发生火灾爆炸后,损失大、扑救难、污染重.通过分析近年来发生的4起扑救较为成功的油库火灾案例发现,火场燃烧面积大,燃烧热值高,油罐变形严重,火灾现场复杂,扑救难度大是油库火灾的现场特点；第一时间灭火力量充足、装备精良、战术运用得当、战勤保障有力是大型油库火灾扑救成功的主要原因.研究大型油库火灾特点和扑救战术,对大型油库火灾扑救现场存在的问题进行分析并提出相关措施,对减少油库火灾事故的损失具有重要价值和意义.%Over the past ten years, the single pot area of oil tank is more than before . There is a great increase than 2000 AD before about the number of fire and explosion. Fire and explosion bring large loss, hard fighting, and heavy pollution. By analyzing 4 depot fire cases in recent years, It was found that the large area of fire burning , high burning calorific value, serious oil tank deformation, the complex scene of the fire, the difficult surpression are the scene features of depot fire. Sufficient first time fire fighting force, well equipment, proper tactics, combat support in the first contact are the main reasons for the success. Study on the characteristics of large oil depot fire extinguishing and tactics of large oil depot fire fighting field, analyzing existing problems and giving some suggest to large oil depot fire fighting and rescue site are of great value and significance to reduce the heavy losses caused by the oil depot fire accident.
