Risk Assessment by FMEA Method and the Impact of Deploying an Integrated Management System (IMS) Risk Priority Number (RPN)

Risk assessment an organized approach to detecting risks and estimating risk has been acceptable to reduce risk. Also, due to the increasing trend of implementation of the integrated management system (IMS) in different industries to improve the level of safety, health and environment standards, we determined to measure the impact of this system's deployment on safety performance monitoring indicators using the FMEA methodology for estimating risk and calculating the RPN.
This study is an interventional study. In this study, first all the high-risk activities of the organization were identified, then, the value of RPN was obtained using the product of intensity (A), probability (B) and discovery (C) depending on the acceptable level of the organization and the Pareto chart (80:20), the organization's unacceptable RPNs were identified and corrective action was taken.
The mean of RPN decreased significantly between 2010 and 2014. Considering the fact that the number of activities has increased with the expansion of the production line, the calculations show that in the years 91 and 93, the amount of RPN significantly decreased compared to the previous years (P The results of this study indicate that the implementation of the integrated management system (IMS) significantly influenced the FMEA risk assessment indicators and improved the safety level of the studied plant.
