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。
In order to clarify and unify the definition and criterion of unsafe action, unscrupulous move is the direct cause of the accident. The contrastive analysis is used to sort out the definitions and judgment criteria of unsafe action in Human Factors Analysis and Classification System (HFACS) and 24 Model , Establishes the corresponding relationship between HFACS and 24Model unsafe action factors, and discusses the application process of corresponding relationship with the actual accident as an example. The results show that unsafe actions defined by HFACS can correspond to insecure actions defined by 24Model through correspondences, and the established correspondences unify the criteria for determining unsafe actions.
