结合烟花爆竹行业安全评价经验,在危险源辨识理论的指导下,运用因果图法对该过程发生的爆炸事故进行定性分析,找出导致事故发生的因素;再运用层次分析法(AHP)进行定量分析,建立层次结构模型,求出各因素的权重,得出各因素的重要程度,从而确定导致事故发生的关键因素,以此作为事故预防的重点。结果表明,人的不安全行为是影响事故的主导因素,此结论符合烟花爆竹行业生产现状,可以为企业制定合理的、有针对性的对策措施提供依据。
Combining the experience of safety evaluation of fireworks industry, under the guidance of hazard identification theory, using causality diagram method to qualitatively analyze the explosion accidents occurred in this process to identify the factors leading to the accident; and then using AHP Analyze and establish the hierarchical structure model, find out the weight of each factor, and draw the importance of each factor, so as to determine the key factors leading to the accident, as the focus of accident prevention. The results show that the human unsafe behavior is the dominant factor affecting the accident. This conclusion accords with the current situation of fireworks industry production, which can provide the basis for enterprises to formulate reasonable and pertinent countermeasures.
