Fire and explosion measures for tanks protection selection algorithm based on quantitative assessment of big breathing

Research objective: Scientific substantiation and development of an algorithm for selecting reservoir fire protection measures based on the big breathing (filling loss) quantitative assessment. Method of research: Theoretical generalization and analysis of approaches for choosing big breathing volume calculating methods, comparative analysis of modern methodological approaches for tank breaths quantitative assessment, as well as using methods for calculating BLEVE effect probability. Results of the study: Analysis of approaches for choosing methods showed that each method has its own calculation specifics, which are reflected in results. Using a comparative analysis of methodological approaches was determined that volumes of big breathing calculated for each method differ by more than 30%. In this regard, algorithm for choosing calculation methods with further forecasting of fire situation is proposed. The algorithm consists of three stages. At the beginning, it is necessary to calculate the filling loss volume, on the basis of them the level of damaging factors is carried out. Depending on the possible situation, protective measures are choosing.
