The Effect of Integrated Management System Establishment on the Safety Performance Indices: A Case Study in a Manufacturing Industry

Safety programs are among the effective factors that may have a key role in upgrading workforce productivity and promotion of qualitative and quantitative indicators of production. The aim of this study was to investigate the effect of integrated management systems (IMS) establishment on safety performance improvement. This study was a retrospective study conducted at the Mazrouf Glass factory in Yazd, Iran. To investigate the effect of IMS establishment on the safety performance during the studied years, indices of injury frequency rate (IFR), injury severity rate (ISR), frequency-severity index (FSI), and Safety T. Score (S.T.S) were used. The paired-samples t-test was used to compare safety indices before and after the establishment of the IMS. The results showed that the establishment of IMS had a meaningful effect on the reduction of the IFR and ISR. Also, no meaningful effect was found between IMS establishment and FSI and S.T.S. IMS establishment could reduce the IFR and ISR, which in turn may promote productivity indicators. Eventually, it could be concluded that IMS establishment can be used as an effective proceeding to improve workplace safety indices.
