ONCE AGAIN ABOUT IMPOSSIBILITY TO PERFORM CALCULATIONS OF FIRE RISKS BY DETERMINISTIC METHODS

Quantitative proofs of impossibility of calculation of fire risks by methods of mathematical description of parameters of inside fires of SÑM (solid combustible materials) by FHF (fire hazard factors) numerical values are given. It is proved that basic parameters of dynamics of SÑM inside fires (linear speed of spread, fire area, combustion rate of fire load, quantity and structure of combustion products of SÑM inside fires, and other) are known to modern combustion science with the error not less than (150–300) %. Therefore calculation of numerical values of FHF and fire risk with error less than (500–1000) % isn't possible in principle. Thereby full uselessness of Method of calculation of fire risk for assessment of adequacy of the level of fire safety of objects and necessity of immediate cancellation of the order on introduction of this method into practice of fire risks calculation is proved.
