Abstract: Using grounded theory and analytic hierarchy process (AHP), this study constructed an indicator system for occupational health risk factors of firefighters from five dimensions: individual factors, protective factors, physical factors, chemical factors, and biological factors. It deeply analyzed the causes of occupational hazards faced by firefighters in training and firefighting work, and proposed prevention and control measures based on risk prevention and control theory. The results showed that the order of factors affecting the occupational health of firefighters was: individual factors>protective factors>physical factors>chemical factors>biological factors. It was proposed that the firefighters' rest and psychological service system should be improved, the multi-dimensional protection work of firefighters should be strengthened, the evaluation and disposal capabilities of physical hazards should be enhanced, and the prevention and treatment of biochemical hazards should be improved.

Key words: analytic hierarchy process, fireman, occupational health, risk factors
