Annotation:

The methods of determining consequences of accidents involving fireball generation as a result of damage or destruction of large-scale equipment, for example, tanks or cisterns with hydrocarbon (including cryogenic) fuel in the epicenter of fire, with the discharge of overheated hydrocarbon fuel in the form of gas, steam, and drop mixture, have been analyzed. The greatest damage during an accident implemented as a fireball is caused by thermal radiation; therefore, specific attention is paid to this fire and explosion factor in the study. The standard methodology for determining the consequences of an accident involving a fireball establishes that the intensity of thermal radiation and the duration of the fireball's existence are determined based on a number of assumptions and not through process dynamics, but at a specific point in time, considering the limiting values of the fireball's thermal characteristics. At the same time, Russian methods for calculating the consequences of fireball accidents, considering the dynamics of fireball development and its movement, which changes its explosion and fire hazardous properties over time, are proposed. Proposals and an algorithm of action to improve the methodology for determining consequences of an accident involving the generation of a fireball for the Russian standard in case of its revision, considering the dynamics of fireball generation, movement, and development, have been developed.
