液氨泄漏的事故树分析

Analysis of ammonia leakage accident tree

对液氨泄漏的原因进行了系统的归类,依此绘制了液氨泄漏事故树。通过结构重要度、最小割集、最小径集分析得出,人为失误及管理缺陷是导致液氨泄露的主要因素。提出防止液氨泄露事故的有效方法,大大提高了液氨安全工作的水平。评价的结果对液氨企业进行安全决策、消除事故隐患具有积极的指导意义。

To classify the reason of the leakage of liquid ammonia systematically, draw the fault tree diagram of the leakage of liquid ammonia. By analyzing the structure importance, minimal cut sets and minimal path sets, we can conclude： the main cause for the leakage of liquid ammonia is human error and administrative defect, draw the feasible methods of preventing the leakage of liquid ammonia, and then improve work standards of safety. Results of the evaluation have the active guidance meaning to the liquid ammonia enterprise on making security decision or reducing safety loophole.
