Abstract: In order to study the correlation among the influencing factors of safety accidents in electric power production,reveal the deep-seated mechanism of electric power safety accidents,based on the statistic cases of electric power safety accidents on the job site,human Factors Analysis and Classi classification System（HFACS） model is used to find out the high frequency Human Factors in power safety accidents.This paper also performs multiple corresponding analysis on the human factors,the equipment factors and the factors that influence the cognition level of workers for safety system.It is found that safety supervision plays an important role in the maintenance of power production safety,and there is a complex nonlinear correlation between power safety accidents and the influencing factors.The cognition level of workers for safety system is dominated by multiple factors,which requires the performance of differentiated and targeted safety system publicity.
