Today, due to the increasing of urban population and hence land shortage, construction of tall buildings are rising. The potential risks of such projects arecomparatively more than the conventional construction as the construction industry is reliant on manpower. Therefore attention to the health and safety of persons engaged in construction projects is essential.The purpose of this research was to identify, evaluate and rank the safety risks that may have harmful effects on human health in high rise building projects. In this research safety risks in high-rise buildings were identified with thru available checklist and interview with experts,and in the next level they wereassessed using 35 expert opinions.Then for quantitative analysis Fuzzy Logic Technique with Trapezoidal Distribution were used and data were also analyzed for uncertainty.After risk evaluation,the degree of critical level of each risk was calculated and for treatment the calculated risks were ranked. Following the assessment, the risk of working at heights in high-rise construction projects, with 89% risk factor and 96% degree of criticalwas identified as the most critical risk.By comparing theresults of risk groups, working at heights, scaffolding, excavation andworking with electricity were rankedas the most critical risk groups, respectively. Occupational risks in High-rise Building projects are very important andmany of them maylead to Short-term or long-term effects on human health.Also these risks influence directly and indirectly on time, quality and cost of projects. Therefore, it is necessary to control and reduce such risks in design and implementation steps.

Due to the increasing population and the need for setting in cities، we witness an increase in high-rise building in Iran. Moreover، because of the ambiguity and complexity، they have various risks potential. Health problems are among this risks for the residents. These risks have short term or long term effects،which can cause illness or even death. In the present study، health risks in high-rise buildings are identified، assessed and ranked. Health issue are identified by conducting interview with experts in high-rise building an using specific health and safety related checklists. Due to ambiguous nature of risks and existence of uncertainly، fuzzy logic technique with trapezoidal distribution was used for quantification. Finally، after risk evaluation and calculation of critical degree of each risk، the risks were ranked. Risk factors obtained over 0. 5 for most of the risks that indicate the importance of Health in high-rise projects during construction phase. The results also showed that the health risks should be assessed before the start of the project in order to reduce or eliminate their impacts. Safety risks in High-rise Building projects is very important. These risks have many impacts directly and indirectly on the time، quality and costs of projects. Therefore، evaluating and controlling each health risk in the design and implementation phases are essential. Most of the risks factors identified in this study، can be prevented by using personal protective equipment. The role of the training people involved in this projects are essential to use personal protective equipment.
