SAFETY PYRAMID ANALYSIS IN ENERGY SYSTEMS

Energy systems are key elements of critically important infrastructures, as they provide the required quality of life for the population, as well as create the necessary conditions for the reliable functioning of various branches of the economy. One of the priorities is to ensure the safe functioning of such systems, and in recent years, considerable attention has been paid to proactive safety methods. Within the framework of these methods, the main efforts are aimed at early identification of violations and deviations in the operation or maintenance of the facility. The building and use of the safety pyramid is one of the areas of implementation of a proactive approach. The paper presents the analysis of statistical data on incidents and detected violations at Russian energy facilities. The analysis made it possible to build the corresponding safety pyramids, as well as to identify that the ratio between the levels of the pyramid significantly depends on the specific type of facility. The possibility of using the safety pyramid to assess expected prevented damage in case of elimination of detected violations is also shown. Examples of assessing the value of prevented damage for energy facilities are given.
