Occupational Health and Safety (OHS) management significantly affects reducing costs, increasing productivity, and social credibility of construction companies and plays a facilitating role in the transition towards sustainable development. This study aims to identify and quantitatively analyze OHS risks in sustainable construction projects in Iran. To do this, first, common OHS risks are identified by conducting library studies. Then, these risks are screened and localized for Irans' sustainable construction projects by surveying 13 experts, selected by snowball sampling method, in a focus group meeting. Afterward, each risk's importance and priority are determined using the Neutrosophic Group Best-Worst Multi-criteria (NGBWM) method, while applying a weight to each expert's opinion. The Neutrosophic sets theory provides the basis for obtaining accurate and more reliable results by considering the uncertainties in the experts' opinions. The findings showed that "the lack of sufficient safety skills of employees due to not allocating time to specialized safety training", "occupational injuries and diseases", "hazards caused by improper design and layout of the project site", "Weakness and inefficiency of occupational health and safety management personnel", and "Negligence and lack of planning for emergency maneuvers", with weights of 0.052, 0.036, 0.035, 0.032 and 0.028 are respectively as the most critical OHS risks in Iran's sustainable construction projects. Finally, reactive and preventive responses were proposed to face them in detail.
