In 2015 most of the EU member states implemented the new requirements of the SEVESO III Directive to their legal environment. There were changes in the area of classifying the hazardous substances, critical infrastructure protection and civil protection. From the point of view of the industrial accidents prevention the domino effects and methodologies for identifying and assessing them are the main challenges for the Slovak Republic. This article presents the currently used methodologies of the company assessment with the potential of the domino effects escalation. The particular methodology for the Slovak Republic that took into account its need, advantages and also shortages of already used methods was created in 2015. It is not exactly defined which procedures are to be used for identifying and assessing the domino effects therefore every member country defined its own methodology. Procedure presented in article fulfilled its intended objectives and thus created the required predispositions for the application of the methodological procedures for Slovak companies. Thus, it has provided step-by-step procedure the competent persons in the Seveso companies and their operators, the competent state administration, as well as neighbouring enterprises with the potential to cause a domino effect with the necessary tool for the implementation of this identification.
