Abstract: In order to improve the effectiveness of prevention and control of unsafe behaviors, firstly, the mechanism of individual unsafe behaviors was studied from a new perspective based on fuzzy trace theory. Secondly, concepts of fuzzy gist space, real safety space, safety valence space, safety risk space and safety decision reliability were put forward, and FTSDM was established, based on which the mechanism of unsafe behavior was described and analyzed qualitatively. Furthermore, a mathematical model of safety decision was established as well, and safety decision reliability was studied quantitatively with it. Eventually the application of FTSDM was demonstrated through simple case studies. The conclusion is that FTSDM can explain the nature of unsafe behaviors from a new perspective and control the unsafe behaviors by improving individuals' ability to recognize real safety space, and the degree of agreement between the feature concept of extracted gist and objective facts is improved through ascending dimension analysis, thus avoiding making decision directly from gist processing.

Key words: unsafe behavior, mechanism, fuzzy trace safety decision model (FTSDM), safety space, decision reliability
