Abstract:

In order to make 24Model achieve better application effect in tracing the cause of accident and formulating accident prevention countermeasures, the detailed scientific explanations of 24Model are critically important. By means of systematic literature review and comparative studies, the logical structure, causation modules and main features of 24Model were deeply examined. The research results show that: the primary theoretical foundations of 24Model are the series of Domino Theory proposed by HEINRICH and improved by BIRD etc., and the series of Swiss Cheese Model proposed by REASON and clarified by SHAPPELL & WIEGMANN, and another one is the Model of Managing for Outstanding Safety proposed by STEWART. The logical structure of the static form of 24Model is established by cause-effect relationship and falls into the sequential category of accident causation models. The specific meaning of the immediate, indirect, root, and radical accident causes in static 24Model can be found from the above three types of accident causation models, management system standards by ISO and the safety culture defined by the authors of this paper. The dynamic form of 24Model takes the process of behavioral conversion to establish its logical structure, and it fully expresses its systemic, dynamic, and non-linear features, and it forms a behavioral conversion system by linking organizational behaviors, namely influence behaviors, and individual behaviors, namely operative behaviors.

Key words: 24Model, logical structure, detailed explanation, systemic, behavior conversion
