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

Introduction: 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. Methods: 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. Results: 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 <0.05). Conclusion: 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

Estimate of the Percent Reduction of the Workers Hearing Loss by Doing a Training Intervention Based on BASNEF Pattern

If we want to provide the efficient training intervention to increase the duration of using heating protection devices (HPDs) by workers, we need a tool that can estimate the person’s hearing threshold taking into account noise exposure level, age, and work history, and compare them with audiometry to find out the percent reduction of workers hearing loss. First, the workers noise exposure level was determined according to ISO 9612, then 4000 Hz audiometry was done to find age and work history. On basis of ISO 1999 the hearing threshold was estimated and if the hearing protection device was not used continuously and correctly, the hearing protection device’s actual performance was reduced adjusted with person’s audiometry. After training intervention, the estimate was done again and was compared with the adjusted audiometry. According to ISO 1999 standard estimation results, the percent reduction of the workers hearing loss level was 6.48 dB in intervention group. This level remained unchanged in control group. The mean score of hearing threshold estimation (standard ISO 1999) was statistically more significant than mean score of hearing threshold (p-value ¡ 0.001). The results show not significant change in control group due to Lack of changing of noise exposure level. In regards to the results of hearing threshold estimation based on ISO 1999 and comparing with workers audiometry, it can be seen that BASNEF training intervention increases the duration of Rusing the HPDs and it could be effective in reducing hearing threshold related to noise
