Introduction: work-related accidents impose irreparable hurt on the national capital. It is necessary to take a series of preventive measures before the occurrence to preserve and protect the human force and reduce accidents. The current study aimed to check safety contradiction using the FMEA method and determine protection indicators of safety performance in the overhaul project. 
Materials and Methods: This study is descriptive-analytical research and an interference method that accomplished 13 jobs in major repairs gas pipeline project. After determining jobs and entering them in the FMEA worksheet, the initial risk score was obtained in this investigation, and after corrective suggestions, the secondary risk priority score was calculated.
Results: The relationship between RPN1 and RPN2 was examined and determined a significant difference between risk priority score before and after corrective measure, and this indicates that these measures are effective (p<0.0005). Among various jobs and before taking corrective actions, the highest number of accidents was related to excavation activities with 15 accidents, which were reduced to 6 after taking corrective measures. Most days lost from work were related to driving job with 6020 days that reduced to 8 days after taking corrective actions; the highest rate of repeat accidents with 62.5 was related to détente activity reduced to 23.14 after taking corrective measures. The maximum intensity factor with 19444.44 was related to the driving activity reduced to 25.25 after taking corrective actions. The accident frequency - severity rate in driving activity with 15.84 was the most reduced to 0.28 after taking corrective measures. 
Conclusion: Due to unacceptable risks and the high rate of accidents in the overhaul of the gas pipeline project, appropriate control measures can be used to reach an acceptable level of risk, which represents the usefulness of the FMEA method.
