Use of the zoning method thermal damage to determine the origin of a fire in motor vehicles

Introduction.The article is a logical continuation of the previously published work on the application of modern methods of establishing the fire centre in motor vehicles, based on the study of thermal damage of preserved structural elements. Materials and Methods: In order to conduct the research, we used general scientific and special methods of scientific cognition, such as systemic, comparative-legal, method of logical deduction and induction, as well as methods of interpretation, structural analysis and observation. The Results of the Study: a fire-technical specialist, having identified these zones and comparing the relative position of the boundaries of these zones, is able to determine the location of fire foci, their number, spatial relationship and, therefore, determine the cause of the fire from a technical point of view. The use of the method of zoning thermal damage to metal structures is the most acceptable way to identify focal signs in cases where, as a result of the thermal effects of fire, all combustible and combustible materials in the car are completely destroyed. Findings and Conclusions: the authors propose to use the method of thermal damage zoning in combination with the traditional method of detecting focal signs when examining a burned car, four zones are differentiated according to the degree of thermal damage, characteristic of structural elements and parts of motor vehicles made of metals and alloys.
