Background & Aims of the Study: Identification of hazards is one of the first goals of risk analysis. Failure mode and effect analysis method (FMEA) is universally defined as efficient procedures for finding potential failures aimed to remove or decrease the risk which is related to them. This study aimed to investigate the effect of control measures on reduction of risk events in an edible oil factory in Tehran.

Methods: This cross-sectional study was conducted in an edible oil factory in Tehran, Iran. For this, a four-member team of safety engineer experts was formed. Some factory units were selected randomly. After that, in all units, probability, severity and detection probability of hazards in all processes and tasks were assessed based on FMEA method. Regarding to the RPN, some control measures were taken to reduce the risk of events. After 9 months, risk assessment was repeated; primary and secondary RPNs were compared with each other to investigate the effect of interventions.

Results: The results showed that highest and lowest probability of hazard were related to installation and can production unit, respectively. The highest and lowest severity of hazard were related to tool and can production unit, respectively. There was a significant difference between the probability of hazard in can-making and filling units, before and after the interventions. There was a significant difference between the severity of hazard in can-making, filling and neutralization units, before and after the interventions. As well, total probability, severity and RPN had a significant difference in all parts of the factory before and after the interventions.

Conclusions: According to the results of this study and the overall risk reduction caused by interventional measures, it can be concluded that, FMEA is a successful method for identifying hazards and risk control measures.
