The provision of chemical, biological, radiation, and fire safety for people, property, infrastructure facilities, and natural environment is the focus of attention of the UN specialized agencies, national governments, managers, and specialists of industrial complexes that manufacture and operate hazardous facilities. According to the analysis, during transportation of dangerous goods by all modes of transport does not ensure an adequate level of risk, as a result of which abnormal situations, various breakdowns, incidents, and emergencies continue to occur. The manifestation of risk causes considerable damage to the transport workers, transportation infrastructure, transported goods and freight units, natural environment, residents of neighboring communities, and people who happened to be in a dangerous zone. The topicality of research is dictated by the necessity of further improving the methods for protection and damage prevention, reduction in social and economic costs and environmental damage. The purpose of research is to develop elements of an integrated security system for zone of dangerous goods by federal railway transport with the possibility to employ them on international scale and in other modes of transport. Improving the concept of dangerous zone during transportation of dangerous goods stands in as the first-priority work stage of the development process. Solving the main tasks of the research was based on such proven and fruitful theoretical and experimental methods as computer modeling, comparative typology and circular expert estimations, statistical analysis, probability theory, theory of similarity, and others. The most meaningful results of the development are both of theoretical and practical importance. The theoretical result consists in development of a new approach to the concept of dangerous zone during transportation of dangerous goods by rail. The practical result involves development of proposals for improvement of the Railway Transport System of Emergency Prevention and Response; introduction of amendments into the Safety Rules for Response to Emergencies related to Dangerous Goods during Their Transportation by Rail; emergency cards for dangerous goods and a number of other technical guidance documents. Processing of the experimental data has established that the expected effectiveness of the development is 7.5-10%.
