【摘要】 采用事故树分析法,建立了以发生火灾或爆炸事故为顶上事件的事故树,从分析事故发生因果关系中的顶上事件开始,直到基本事件,由果到因、自上而下地分析了某化工厂液化石油气储罐销爆过程中的危险因素。通过对液化石油气储罐销爆处理过程中潜在危险因素的系统分析,得到了事故树的各阶最小割集,确定了液化石油气储罐销爆过程中的主要危险源,提出了相应的安全预防措施,保证了该化工厂液化石油气储罐销爆过程中的安全。更多还原

【Abstract】 The underlying dangerous factors in the explosion elimination processing of LPG(liquified petroleum gas) tanks in a chemical plant in Xiangfan city, Hubei province, were systematically analyzed from the top tree event to the bottom tree event,and from the results to the causes by a fault tree taking a fire or explosion accident for the top. The minimum cut-set of the fault tree was obtained, the major dangerous factors in the explosion elimination processing of LPG tanks were realized, and the corresponding prevention measures to ensure the safety of the explosion elimination processing were suggested.更多还原
