2012年2月28日，河北凯普化工有限公司发生硝酸胍爆炸，有限公司、中国，造成25人死亡，4人失踪，46人受伤。为了探究事故背后隐藏的因果关系，采用故障树分析法（FTA）和人因分析与分类系统（HFACS）对事故进行了系统分析。首先，利用事故树分析法对事故原因进行深入分析，直至找出导致硝酸胍爆炸的所有基本因果事件，并绘制出硝酸胍爆炸的事故树图。其次，针对基本因果事件中的不安全行为，运用HFACS模型分析了导致不安全行为的三个层次的因素，包括不安全行为发生的前提条件、不安全监督和组织影响。最后，根据故障树分析和HFACS分析结果，得到了事故原因的完整逻辑图。FTA和HFACS事故分析方法可以识别爆炸事故中的人为因素和事故演变过程，为事故调查提供参考。
On 28 February 2012, a guanidine nitrate explosion occurred at HEBEI KEEPER Chemical Industries Co., Ltd., China, resulting in 25 deaths, with 4 missing individuals and 46 injured. In order to explore the causal relationship hidden behind this accident, fault tree analysis (FTA) and the Human Factors Analysis and Classification System (HFACS) were used to systematically analyze the incident. Firstly, FTA was used to analyze the causes of the accident in depth, until all the basic causal events causing the guanidine nitrate explosion were identified, and a fault tree diagram of the guanidine nitrate explosion was drawn. Secondly, for the unsafe acts in the basic causal events, the HFACS model was used to analyze the three levels of factors that lead to unsafe acts, including the preconditions for unsafe acts, unsafe supervision, and organizational influences. Finally, based on the analysis results of FTA and HFACS, a complete logic diagram of the causes of the accident was obtained. The FTA and HFACS accident analysis methods allowed for the identification of human factors and the accident evolution process in the explosion accident and provide a reference for accident investigation.
