The effect of integrated management system on safety and productivity indices: Case study; Iranian cement industries

Nowadays, with implementation of management systems and environment management and due to the influence of safety and health issues on working processes, organizations have also sought to acquire health and safety management systems. This study which aims to examine the influence of integrated management system on safety and productivity indices has retrospective experimental nature. It was conducted in Cement Factories in which three systems are used: quality, environment and safety systems. The collected data were: accident reports and the investigation of events in 6 years during 2005–2010 (3 years before and 3 years after the implementation of the system). The safety indices that used in this study are: IFR, ISR, FSI, and Safe T. Score. Then, the data analyzed with the T-test, mean and standard deviation. The results showed a significant difference between various safety indices before and after the implementation. The examination of production indices such as increasing rate of productivity and production indicates the influence of these systems on production and productivity indices. The results have showed that the safety system existence cannot ensure productivity increase. Indices definition can be helpful for the safety system effectiveness and system continual improvement. It is important to say that there might be various indices definition in different industries.
