In this study, a safety classification model based on analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method (FCE) was established to prevent and control the risk of repetitive diving for leisure divers. Sixteen key risk factors were selected by literature analysis and Delphi method, covering four criteria levels: physiological state, diving operation, interval accumulation and environmental equipment, among which the maximum diving depth, underwater residence time and water surface interval time were the core indicators. AHP is used to determine the weight of each factor, and FCE is combined to realize the quantitative evaluation of safety level. The model is verified by 35 real repetitive diving cases, and the results show that the coincidence rate with expert evaluation is 82.9%, which can effectively distinguish low-to-high risk scenarios. The research shows that the core of repetitive diving safety lies in standardizing diving operation, optimizing interval management and paying attention to individual physiological state. This model provides a scientific tool for the course design of diving training institutions, the self-evaluation of repetitive divers and the industry supervision, and has important practical value for reducing repetitive diving accidents and promoting the sustainable development of diving.
