Background: The FMEA, at first, is identified dangerous modes in the process and then, it has provided proper control measures which needed to reduce risk level. This study aimed to investigate of the risk level before and after implementation of control measures in an edible oil factory.

Methods: This cross sectional study was conducted in an edible oil factory in Tehran, Iran. The FMEA technique was used to identify failure modes related to equipment existed in five units of mentioned factory. After that, in the all units, risk priority number in all process was assessed based on FMEA method. Regarding to the RPN number, some control measures were taken to reduce risk of events. After 9 months, risk assessment was repeated and primary and secondary RPNs were compared with each other to investigate the effect of interventions.

Results: The results have shown that the highest probability of danger was related to installation unit. Probability of danger in this unit before and after interventional actions was 4.5 and 3.25, respectively and the highest amount of severity was related to tool production. The marginal homogeneity test was showed the positive effect of control measures on the risk level in the factory. There was a significant inference between before and after data in RPN in the unit tool production, neutralization unit, and installation unit. The Tests of Within-Subjects Effects showed that, there was a statistical significant inference between before and after data in total average of RPN criterion (pvalue<0.001).

Conclusions: Finally, it can be concluded that, the high risk level in the factory units has reduced after applying interventional corrective measures, these actions have been useful and it can be mentioned that, the FMEA has been successfully able to identify and to control risk level in the factory.
