基于事故树分析的化工实验室火灾爆炸危险性研究

Study on Risks of Fire and Explosion in the Chemical Laboratory Based on Fault Tree Analysis

根据化工类实验室火灾爆炸事故的事例,建立了基于事故树的可燃气体发生火灾爆炸的模型。由模型可知,实验室可燃气体泄漏发生火灾爆炸事故的基本事件,运用事故树分析方法中的最小割集合和最小径集合以及结构重要度排序。在此基础上对实验室火灾爆炸事故分析研究。并提出具体的预防和改进措施。

According to the typical case of fire explosion accident in the chemical laboratory, a fire explosion accident tree was established. The basic event of fire explosion accident caused by combustible gas leakage in laboratory was analyzed. The minimum cut set, the minimum path set and structural importance in the accident tree analysis were applied to analyze the laboratory fire explosion accident. And specific prevention and improvement measures were put forward.
