Performance Assessment Methodology of Occupational Health and Safety Management System

Although occupational health and industrial safety management systems were implemented a while ago and are maintained at many enterprises globally, until now, no sufficient proof of the efficiency of such systems in terms of prevention and mitigation of the number of accidents, industrial accidents, and professional illnesses has been obtained. Therefore, further development and distribution of such systems depend on the ability to demonstrate their efficiency and performance, which can be achieved by implementing relevant methods and tools to stimulate the operational efficiency of their systems. Using expert assessment methods and mathematical processing of the results, eight mandatory and sufficient indices of performance of a functioning integrated system of an oil and gas company, whose main business activity is the production of petroleum products, have been identified. The company operates hazardous production facilities in Russia. The obtained indices describe the injury frequency, the level of employees’ training and their satisfaction with personal protection equipment, the nature of violations of safety requirements, and funding the events aiming to improve the integrated occupational health and industrial safety management system. Using the weighted average value of the established indices of system’s performance has been considered. Applying the Harrington’s desirability assessment method, the satisfactory level of performance of the existing integrated system has been determined. The integrated system performance assessment must be conducted by employer on an annual basis, which facilitates the development of effective corrective measures and the continuous improvement of the system. The established performance indices may change depending on strategical and tactical goals of the company. The proposed methodology of comprehensive quantitative assessment of integrated system can be used by employers in order to improve the existing management systems.
