PROVIDING A MODEL FOR EVALUATION THE PERFORMANCE OF OHS USING THE SAFETY SCORECARD METHOD - CASE STUDY OF GAS SUPPLY IN TEHRAN PROVINCE

Performance assessment in any management is a key step in continuous improvement. While occupational safety and health management has been in place for several years, the question of how to control and evaluate the performance of this system still remains. Safety management needs to focus on predictive indicators, rather than on retrospective indicators focused on failure. The Safety Scorecard tool is designed to facilitate decision support and has the ability to integrate performance metrics with advanced metrics. The gas industry is considered a critical industry from the HSE perspective due to the quality and quantity of materials used and having three characteristics of high complexity, low flexibility and high vulnerability.

Following interviews with 6 experts from the provinces of Tehran province and also 4 HSE physicians who all had a master's degree and at least 20 years of experience in their field of work and HSE, general criteria and indicators affecting occupational health safety In Tehran Gas Supply Company, obtaining and using a questionnaire in comparison with a couple, the prioritization index was done based on the ANP model and using the opinions of experts. Then, by designing and completing the safety score card in the sample units, the performance of occupational safety and health in Tehran Gas Supply Company was assessed. The model presented in this research was implemented in Tehran Province Gas Department in 7 regions, which were finally compared with each other.

Among the 8 performance indicators approved by experts, the occupational hazards analysis report index with a weight of 0.229 was in the first priority and the incident analysis index with a weight of 0.049 was in the eighth priority. Therefore, there is a need to create a strong mechanism for recording, analyzing and learning about all accidents and quasi-accidents. By designing the safety score card method, 7 units of the company were compared in terms of safety and occupational health performance during December 2017-2019. In the first year, case study 6 with a score of 5.6, more appropriate situation and case study 3 with a score of 0.048 Performance was more challenging and in the second year, case study 1 with a score of 4.08 had a more appropriate situation and case study 2 with a score of 6.66 had a more challenging situation. Therefore, the existence of continuous HSE monitoring system in the regions is very necessary and the performance of the regions has improved a lot after the presence of HSE observers.

Finally, a model of safety scorecard that integrates management indicators at different levels of an OHS management system, along with the implementation method of scoring safety cards, was proposed for Tehran Gas Supply Company. The model presented in this study includes action and response indicators, has the ability to monitor the performance of occupational safety and health management and helps managers and health and safety experts in industries and organizations to evaluate the effectiveness of this system.
