HFACS与24Model不安全动作因素对应关系研究

A comparison of HFACS and 24Model in categories of unsafe acts

不安全动作是导致事故发生的直接原因,为明确和统一不安全动作的定义及判定标准,采用对比分析的方法梳理人因分析与分类系统(HFACS)和24Model中不安全动作的定义和判定标准,建立HFACS与24Model不安全动作因素的对应关系,并以实际事故为例论述对应关系的应用过程。结果表明,HFACS定义的不安全动作可以通过对应关系与24Model定义的不安全动作相对应;所建立的对应关系统一了不安全动作的判定标准。

Unsafe acts are the direct causes of the accidents. In order to clarify and unify the definitions and judgement criteria of unsafe acts in HFACS and 24 Model,a comparative analysis was used and a corresponding relationship in unsafe acts between HFACS and 24 Model was established and a case study was showed to describe the application of the corresponding approach. The results show that unsafe acts defined by HFACS can be associated with the unsafe acts defined by 24 Model based on the corresponding relationship,and the judgement criteria are unified by the corresponding relationship.
