基于事故树分析方法的氰化物中毒事故模式研究

Study on the Cyanide Poisoning Accident Model Based on Fault Tree Analysis

使用氰化物过程中,人员稍有不慎,就可能发生中毒事故。从理化特性、中毒途径及中毒症状、生产及储存过程、安全管理四个方面讨论了氰化物危害性,运用事故树分析方法,编制了氰化物中毒事故树,得到了事故发生的不同模式,定量分析了各基本事件对氰化物中毒事故的影响程度,为企业员工预防氰化物中毒事故的发生提供了理论依据。

In the process of using cyanide, workers are prone to poisoning accident. In this paper, the hazard of cyanide was discussed from four aspects of physical and chemical properties, poisoning route and poisoning symptoms, production and storage process, safety management. The cyanide poisoning accident tree was compiled by using fault tree analysis method, and different accident patterns were obtained, and the influence degree of each basic event to cyanide poisoning accident was analyzed quantitatively, which could provide the theory basis to prevent the cyanide poisoning accident for workers.
