Abstract

A comparative study was conducted to compare the accident cause analysis methods of Fault Tree Analysis (FTA) and 24Model. A major accident - Xinjia Hotel collapse accident was selected as the research object, the causes of the accident were reanalysed and accident prevention countermeasures were designed based on 24Model and FTA respectively, and the systematic characteristics of 24Model were summarized. The research shows that both 24Model and FTA can carry out risk assessment, accident cause analysis and preventive countermeasure design based on their own rules. Different from FTA, 24Model has static and dynamic structures of specific forms, the definition of causes and factors in the model is more comprehensive and the analysis method is more hierarchical and normative. 24Model can analyse the deep-level cultural and system causes, but the analysis process does not use quantitative methods, only use qualitative methods. 24Model has 8 systematic characteristics, such as integrity, hierarchy and dynamics.
