Thus, over 2200 legal provisions have been established for the prevention of accidents on construction sites. Not only contractors are unable to implement all provisions, but also it is hard for regulatory bodies to implement all rules, but they are also hard to remember and attend to by regulatory forces. Therefore, identifying the set of codes with the highest effect on reducing accidents would be most beneficial. The aim of this study was to determine the most effective legal provisions in reducing accidents on construction sites in Zanjan city.</font></span></span></span></p> <p style="margin: 0cm 0cm 0pt; text-align: justify; line-height: normal; unicode-bidi: embed; direction: ltr;"><span style="font-size:14px;"><span style="font-family: times new roman;"><font color="#000000"><b><span new="" times="">Methods: </span></b><span new="" times="">In this study, 378 work-related accidents in construction sites in Zanjan city, already registered in the Labor Inspection Authority, were investigated .Then the codes that had not been respected in the construction industry accidents were identified.
