ESTIMATION OF THE EXCESS PRESSURE OF AN EXPLOSION USING THE EXAMPLE OF A GAS EXPLOSION AT A GAS FILLING STATION IN THE VILLAGE OF CHAGODA

Indoor explosions pose a serious threat to human life and health, as well as cause significant material losses. Therefore, assessing the excess pressure of an explosion is an important task for ensuring safety and developing appropriate prevention and protection measures. This study is relevant in light of the increased interest in safety and explosion prevention. The study will make it possible to assess how the coefficient, which takes into account the leakiness of the room, affects the excess pressure of the explosion and develop recommendations for creating safer indoor conditions. This is of great importance for industrial enterprises, where the risk of explosions is particularly high, as well as for the development of regulatory documents and building regulations that take into account the safety of premises. The paper identifies the shortcomings of the methodology described in NPB 105–03 and SP 12.13130.2009 when assessing the excess pressure of an explosion. It is shown how strongly the value of the room leakage coefficient affects. It has been clearly demonstrated that improper use of this coefficient can lead to a significant underestimation of the possible consequences of accidents. The paper shows the value of the leak coefficient, which should be taken into account. Thanks to this study, it is possible to more accurately determine the parameters of the explosion, which in turn allows you to choose the best methods of protecting equipment and buildings, as well as determine the safe distance from the epicenter of the explosion to ensure the safety of people.
