油库储油罐火灾爆炸事故树分析

Fault Tree Analysis of Fire and Explosion in Oil Storage Tank

油库储油罐储存的油料具有易燃易爆性且存储量大,一旦发生事故后果严重.针对油库储油罐安全管理点多面广的特点,分析储油罐火灾爆炸事故的相关影响因素和条件,建立完善的事故树模型.通过定性分析理清火灾爆炸事故与基本事件的逻辑关系,定量分析获得顶上事件发生的概率和各基本事件的结构重要度顺序,找出储油罐存在火灾爆炸事故隐患的重点部位,制订科学合理的安全信息监控点策略,为油库安全管理手段向信息化迈进,预防事故的发生提供决策依据.

Large quantity of oil in oil storage tank is highly flammable and explosive. If any accident happens, consequences are beyond measure. According to characteristics of broad area of the security management in oil storage tank, and by analysis of the influencing factors and conditions related to fire and explosion accident in the oil storage tank, integrated fault tree model is established. The logical relationship between the accident and the basic events is clarified by carrying out qualitative analysis, while the structure importance factors of the basic events are ranked by carrying out quantitative analysis. Therefore the emphasis part in which there is potential of fire and explosion is found, and reasonable strategy for setting the security monitoring points is worked out. provide basic for decision-marking of informational application in security management.
