Concept of technogenic risk management

There are proposed conceptual positions and levels of decision-making on provision of the safety, social and medical protection of the human on the base of the assessment, analysis and risk management in different areas of human activity in normal and emergency conditions under the exposure to man-made and some natural hazard sources. At the base of developed applications there is a unified approach to the development and use of modern risk assessment methodology: the elaboration of a common method of the risk assessment and, basing on it, specific and simplified methods for concrete sources of hazard impact. This structure of methodological bases of risk assessment, in its full development makes it more transparent and comparable as well specific methods, as the support of decision-making on protective and other measures from different sources of danger. There were formulated proposals for universal safety standards (SSs) and other levels of decision-making on safety, social and medical protection of the population and staff of hazardous industries, including acceptable levels of risk. For the establishment of SSs and other decision-making levels, a special risk index is used: the relative damage (ratio of years of life lost to a year of stay-at-risk). This index is most appropriate for evaluation, comparison and management of risk, especially in conditions of two or more acting danger sources. On the base of universal SSs there are developed branch main SSs for certain isolated sources of danger. They are expressed in those indices (specific risk indices or impact indices in their different definitions), which by now are widely used in the practice or will be chosen for practical use in the future. In the ensuring human safety in normal conditions, the main use of the risk assessment is the development and support of SSs and other levels of decision-making. In emergencies the specific risk assessment besides to the establishment the decision-making levels is essentially needed to make justified optimal decisions on the measures of social and medical protection of the population and professionals.
