Abstract:

In order to promote wide application of 24Model in official accident investigation, and to explore shortcomings of accident investigation reports, with Xiangshui "3·21" explosion accident as an example, accident causes were analyzed based on 24Model, and their action paths were plotted. Then, comparison was made with investigation report. The results show that causes of the accident in Tianjiayi company include unsafe acts, unsafe conditions and lack of safety capability at individual level, as well as lack of safety culture and safety management system at organizational level. In regard of causes at the latter level, the investigation report does not make a detailed analysis, without revealing accident mechanism or accurately defining and dividing various types of responsible persons. However, 24Model, based on complete definition of every cause and factor, is able to summarize the causes with systematic analyses and clarify definition of responsible persons and their liability distribution.

Key words: 24Model, accident cause, system analysis, accident investigation report, Xiangshui explosion accident, comparative study
