The number of occupational accidents in postwar japan has decreased to about 10% of the peak at present. Although the analysis of occupational accidents in the construction industry has been carried out by linear analysis, which is a simple linear model, new efforts based on the concept of Safety-II are required now that the occurrence of disasters has decreased. In this study, we tried to analyze the cause of the crash disaster in the construction industry by FRAM (functional resonance analysis method), which is a nonlinear model. As a result, it was visualized by FRAM that there are multiple causes of disasters in the performance that is usually overlooked, as well as the causes obtained by conventional linear analysis methods, and that they can lead to disasters by affecting each other. It is shown that disaster prevention can be made by finding and responding to signs of disaster by FRAM.
