The Effect of Integrated Management System on Risk Priority Number of Environmental Assessment by FMEA Method in Yazd PersepolisTile Factory

Considering the increasing trend of implementing integrated management system (IMS) in different industries to improve safety and health standards, environment and quality, this study aimed to evaluate the impact of IMS system on environmental indicators using FMEA method and risk priority number (RPN). Indicators were compared before and after the IMS implementation.
This is an interventional research that was carried out in a Persepolis tile factory during the years 2010-2011 (before the intervention) and the years 2012 to 2014 (when IMS system was implemented). First, environmental pollution activities were identified, and then RPN was obtained using the product of the intensity, probability, and detection. Considering the acceptable level for the organization and the Pareto charts (80:20), unacceptable RPNs were identified and corrective actions were taken.
The average RPN decreased from 2010 to 2014. Although activities has increased due to expansion of the production line, the results showed that in 2012 (the beginning of IMS implementation) and 2014, RPN was significantly decreased.
The results indicate that the implementation of the IMS has had a significant effect on the environmental assessment indicators by FMEA method and has improved environmental conditions
