Human errors are one of the most important causes of occupational accidents. Human errors have different causes, but in all cases, human cognitive abilities and limitations play important roles; in this research, the relationship between occupational cognitive failures and work-related accidents in heavy equipment operators of Shahid Rajaee Port Complex has been investigated. METHODS: This research was done through the field method. A sample of 332 people was selected by a stratified sampling method among all heavy equipment operators. The data gathering tool contained a 30-item occupational cognitive failure questionnaire. Furthermore, regression analysis method was used to test the hypotheses. RESULTS: The results of this study showed that cognitive failures of occupational accidents on direct work-related accidents in heavy equipment operators of Shahid Rajaee Port complex have a direct effect (P < 0.00). Further more, variables that modify the research are age, work experience, working hours, educational level, type of occupation, and marital status of the operators. CONCLUSION: Regarding the direct relation between cognitive occupational failures and occupational accidents, one can predictive this result that the occupational cognitive failure questionnaire can be used as a predictive tool in accidents of Shahid Rajaee Port Complex.
