Then the questionnaire is designed based on these risks and is distributed among the statistical sample. After reviewing the validity and reliability of the questionnaire, the mentioned factors are ranked based on the costs of providing workforce for safety and health of workforce using the fuzzy hierarchical analysis method. The results of fuzzy hierarchical analysis method show that the factor of people getting stuck between machines is the most important that should be considered in all stages. The next most important factor is the accident with the machines. The third factor is the throwing of materials from machines. Thus, due to financial constraints in this regard, in order to manage safety in construction projects, it is necessary frst to consider the factors that have priority.
