Development of an Approach to Assess the Consequences of Fuel-Air Mixtures Explosions Taking into Account the Development Features

Abstract

Introduction. In the study of the problem of the impact of negative factors from explosions at gas stations on people and the infrastructure of settlements, a probabilistic approach is often used. The limitation of this approach is that when it is implemented, the concept of clutter of the surrounding space does not reflect the relationship between the area occupied by buildings and the total area affected by the shock wave. Therefore, this article is devoted to the development and justification of an approach to assessing the consequences of explosions of fuel-air mixtures (FA), taking into account the peculiarities of the development of settlements. The work objective is to develop an approach for assessing the consequences of explosions of fuel-air mixtures, taking into account the development features. The solution to this problem will facilitate decision-making for the development of effective protective measures for surrounding objects.Materials and Methods. The authors have conducted an analytical review of the research results in the field of study and the existing approaches to assessing the consequences of explosions at filling stations (FS) and gas stations (GS), based on the specific conditions of their location on the territory of settlements.Results. An approach has been developed to assess the consequences of explosions of fuel-air mixtures, taking into account the development features. The main causes, types of accidents with an explosion at a gas station and the scale of their consequences have been identified. Along with the theoretical justification of the issue under consideration, the authors provide a detailed description of the applied research methodology, as well as the characteristics of the objects of research, taking into account their location. When calculating the consequences of explosions of fuel-air mixtures, it was proposed for the first time to use a development density factor equal to the ratio of the area of the existing facilities to the total area of the territory affected by the shock wave. This approach justifies the need to apply additional protective measures in the areas where gas stations are located. The methods of analysis used are described in detail with justification of the reliability of the measurement results.Discussion and Conclusion. The application of the approach proposed in the article for calculating the consequences of an explosion of fuel-air mixtures, taking into account the development density, makes it possible to control the location and the level of risk from possible explosions at gas stations in a real situation. The proposed approach for calculating the consequences allows you to quickly assess possible risks in real time and plan specific measures to minimize them in accordance with the existing situation in the area of the gas station.
