A purpose of this article is to contribute to the question: “How the major accident safety information campaigns for the public have been made in recent years” with regard to legal requirements and regulations for measures to prevent or limit the consequences of serious chemical accidents. The regulations on the control of major accident hazards involving dangerous substances in Europe and in the Czech Republic involve public information planning with the purpose of making citizens aware of industrial risks, and possibilities to limit consequences of a major accident that have potential influence on public health, environment and assets, by implementing required behavior and safety measures. In this study we deal with the analysis of the Czech public information approach according to the EU legislative framework, and describe this approach using a set of examples. Our aim is to describe and compare the most important legislative regulations concerning the public information process and the measure of implementation of the EU regulations into Czech ones, and based on this comparison we point out the actual trend.
