Abstract In this research, the analysis of the technical views of experts and the management of construction projects in Tehran Municipality regarding the assessment of the risk of work accidents in the development, construction, and operation stages of construction projects, using the FMEA analytical approach in two fuzzy and non-fuzzy dimensions (CRISP) with twelve The index in the construction stage and six indicators in the operation stage were carefully evaluated and measured. Risks caused by the collapse of nearby buildings on workers, the collapse of buildings in demolition and reconstruction projects, which are mainly related to non-standard demolition operations, as well as the fall of people due to welding operations and falling from scaffolds, lifts, and cranes, as the most dangerous and most frequent occupational accidents in the industry. The buildings of this area were identified. Based on the analytical findings of this model, the average risk of occupational accidents in the construction industry reached 346 in the construction phase and 97 in the operation phase. The fuzzy equivalent values for risk prioritization in the construction and operation stages showed 355 and 129 numbers on average, respectively. Following the implementation of the correction suggestions, the risk values obtained for the construction phase in the non-fuzzy mode were reduced to 247 and in the fuzzy mode to 255. In contrast, the exploitation phase was reduced to 58 in the non-fuzzy mode and 84 in the fuzzy mode.

Abstract Occupational incidents in the oil industry have difficulties and problems in the various phases of construction and operation. In this research, we tried to investigate the effect of oil industry risk in phase construction in one of the largest oilfields in the country, Yadavaran field in Khuzestan province. For this purpose, the FMEA model has been used that is typically used to assess the risk of occupational accidents. According to surveys, interviews and statistics, 47 job incidents were identified during the construction phase of this oil field and the details were collected. According to the obtained results, the value of the risk priority value is obtained by an average of 212. Also, based on the type of events classified, several corrections’ suggestions were proposed, which is expected to decreased the RPN to 133.2 which shows a reduction of 37% of the risk priority number. Although changes have been made in the form of low-cost, continuous and periodic suggestions that showed the positive impact of the reform in this area.
