This article provides a theoretical study and generalization of the definition of the essence of danger, threat and risk in the economic security of an enterprise. The presence of danger creates a system of organizational and economic actions to protect the enterprise from the onset of risk. Schematically, the interdependence of these categories is shown which correlate with each other. At the same time, the systematization method was used to identify deterministic features and the grouping method to clarify conceptual approaches.
An effective approach to solving the problem of reducing man-made hazards is the use of specialized systems for forecasting and minimizing risks. The theoretical basis for hazard assessment is probabilistic safety analysis (IAB). The most common method of assessing the danger and accident is the development of formalized models of events is the use of logical-probabilistic models "failure tree" (FTA) and "event tree" (ETA). These methods are widely used in the world to analyze the risk of accidents at facilities with increased levels of danger.
The evolution of the life safety phenomenon is considered, the theoretical aspects are analyzed and the essence of the concept "safety of life" and its interpretation in the scientific environment are analyzed. The model of development and scientific principles of life safety is explored. Author's definition of life safety is proposed.
