ANALYSIS OF STATISTICAL DATA ON FIRES IN THE THICKNESS OF COMBUSTIBLE MATERIAL
Abstract and keywords
Abstract:
The article considers approaches to the statistical analysis of parameters characterizing fires at solid waste storage facilities. A reasonable choice of analysis methods based on the combined application of qualitative matrix analysis of the structure of factors (parameters) and quantitative analysis of their homogeneity using elements of variance analysis is made. The principle of grouping statistical material is determined, taking into account the presence of a parameter having a discrete structure, such as "The number of devices for supplying extinguishing agent" in further analysis, it is replaced by a conditionally continuous parameter - "Consumption of extinguishing agent". It is shown that the homogeneous parameters are "fire area" and "specific flow rate of fire extinguishing agent". It is revealed that one geometric characteristic of a fire across the entire data set is statistically insufficient for homogeneous conclusions about the use of forces and means of fire protection units. In practice, this means that the same fire area is extinguished using a different number of extinguishing agent supply devices (Total consumption of extinguishing agent) and for different times. For a reasonable conclusion about the specifics of the use of fire departments, additional information is needed, presumably about the depth of gorenje (smoldering) in the thickness of the combustible material

Keywords:
