基于组织与人因分析系统的塔吊事故分析

人因分析系统将事故致因简化为潜在因素作用于个人不安全行为，个人不安全行为导致事故发生。根据塔吊事故特点，构建组织与人因分析系统，其作用机制为潜在因素作用于个人不安全行为和组织不合理决策，组织不合理决策和个人不安全行为作用于事故。结果表明:塔吊事故主要有3类作用机制，其中安全文化、个人状态和班组状态对事故的影响最大。针对事故作用机制和作用强度，从组织和个人两个方面提出相应对策与建议。

Tower crane accident analysis based on organization and human factor analysis system

The human factor analysis system simplifies the causes of accidents to potential factors acting on personal unsafe behaviors, and personal unsafe behaviors lead to accidents. Combined with the characteristics of tower crane accidents, an organization and human factor analysis system was proposed. Its mechanism is that potential factors act on personal unsafe behaviors and unreasonable organizational decisions, and then the two act on accidents. Results show that there are three main types of action mechanisms in tower crane accidents. Safety culture, personal status and team status have the greatest impact on accidents. In view of the mechanism and impact intensity of the accident, corresponding countermeasures and suggestions are put forward from both organizational and personal aspects.
