相对于其他事故致因链来说,现代事故致因链把管理因素作为事故的根本原因,且将管理因素具体化,便于实践操作。依据组织行为学的原理,傅贵教授提出了行为安全的“2—4”模型,该模型为新型现代事故致因链。在该模型中,事故的原因首先被分解为组织行为、组织成员个人行为两个层面,其中,将组织行为细化分解为指导行为、运行行为两种,将个人行为细化分解为习惯性行为、一次性行为,共四个行为阶段,分别对应事故的根源原因、根本原因、间接原因和直接原因。具体内容分别是安全文化,安全管理体系,安全知识、意识和习惯,不安全动作和不安全 Compared with other causes of accident chain, the cause of modern accident caused by the chain management factor as the root cause of the accident, and the management of specific material to facilitate practical operation. According to the principle of organizational behavior, Professor Fu Gui put forward a “2-4” behavioral safety model, which is a new type of modern accident-induced chain. In this model, the cause of an accident is first decomposed into two aspects: the organizational behavior and the individual behavior of the organizational member. The organizational behavior is divided into two parts: the guiding behavior and the operating behavior. The personal behavior is divided into the habitual behavior , One-off behavior, a total of four stages of behavior, respectively, corresponding to the root cause of the accident, the root causes, indirect causes and direct causes. Specific content is safety culture, safety management system, safety knowledge, awareness and habits, unsafe action and insecurity
