| Summary: | The development of the Safety Management System (SMS) in chemical industry appears as one of the important requirements introduced by the EU "Seveso II" Directive on the control of major-accident hazards. This paper aims to provide a contribution regarding the SMS structure and the definition of the tools for assessing the effectiveness of this system by means of safety performance indicators. The performance indicators are linked to a reference values or policy targets, illustrating how far the SMS is from the desired level. We developed a system of performance indicators for SMS in chemical industry by using the concept of environmental performance indicators defined in standard ISO 14031. A set of three types of safety system performance indicators was proposed: management performance indicators, operational performance indicators and safety status indicators. These indicators represent the most important factors in the linkage between a possible cause of an accident and its effects.
