大型油罐区火灾风险严重度指数评价

摘要

Against the high fire risk and extinguishing difficulty of large oil tank farm, the typical fire accident scenarios and accident frequency were analyzed and identified, and fire risk severity index was introduced to assess the relative fire risk level and rank. Moreover, estimation methods of specific risk severity index for pool-fire, tank-fire and VCE (vapor cloud explosion) were illustrated and described, and the example was assessed. This research provided a basis for oil storage tank area planning, management, accident prevention and emergency rescue.%针对大型油罐区火灾风险高、扑救难度大的特点,分析典型火灾事故场景及发生频率,引入火灾风险严重度指数来评价罐区火灾风险的相对影响水平和等级,给出池火、油罐火和蒸气云爆炸场景的火灾风险严重度指数评价方法,并以实例剖析.该研究可为大型油罐区火灾风险防范、消防规划和应急救援提供依据.
