Introduction: Failure Mode Effect Analysis (FMEA) method used To identify the defects of the parts of a machine or a manufacturing process that includes several machines. The aim of this study was to compare a variety of prioritized control measures in reducing the number of risks in one of the edible oil factories.

Method: This was a longitudinal and interventional study that carried out in one of the edible oil factories in Tehran province in 1393. After an initial assessment by an expert team, corrective solutions were implemented and Risk Priority Number (RPN2) was obtained. Data were analyzed using SPSS version 23.

Results: In the studied industry, 73 risks in five major units of the factory were identified by using the Failure Mode Effect Analysis (FMEA) risk assessment method. The highest risk priority number (RPN) was 80 and the lowest was 4. The highest possibility of danger was related to the factory installation unit. Possibility of danger in this unit before and after the interventional actions was 4.5 and 3.25, respectively. The highest amount of hazard severity was related to the tool making unit. The mean of severity of dangers in this unit before and after interventions were 4.75 and 3 respectively. There was a significant difference before and after the intervention (p<0.05).

Conclusion: According to the results of this study, it can be concluded that failure mode effect analysis (FMEA) is a very useful evaluation method that focuses on high risk processes.
