INITIAL DATA FOR FIRE RISK ASSESSMEN CALCULATION

There is carried out the analysis of the initial data structure used for numerical modeling of fires based on regulatory requirements and investigation in performance of calculations to determine the estimated value of fire risk for municipal buildings. It is shown that the calculation result depends on the composition and quality of the initial data. And as a consequence, the quality of the developed fire prevention measures also depends on the composition and quality of the initial data. There is given the classification of the initial data used in calculations to determine the estimated value of fire risk for the object of protection. The two main data sets are distinguished: those obtained on the object and those determined by formulated scenarios. A list of parameters that have a qualitative and quantitative impact on the calculation result is provided. Methods for determining the quantitative values of such parameters as the fire area, specific mass of the combustible load are presented.
