In the first section we present the analysis of existing approaches to risk analyses in the European Union, in the area of the control of major-accident hazards involving dangerous substances. In the second section we focused on and analyse the index-based deterministic method developed and used for evaluation of emergency planning zone in Italy with respect to Seveso II Directive. The results of the analysis have been used both to evaluate the purpose of the emergency planning zone and to evaluate the criteria proposed for calculation of emergency planning zone distances. Individual steps of the presented emergency planning methodology have been identified, and the two different applications for toxic gas release and explosion have been described. The results obtained allowed us to start a systematic comparison of selected states with index-based method for emergency planning zone calculation in the future.
