The work is devoted to the solution of an actual scientific task in the field of civil protection, namely, the analysis of methods of researching thermal damage to structures due to fire at critical infrastructure facilities, with the aim of further developing a model for preventing terrorist emergencies at critical infrastructure facilities of Ukraine.
This work is a continuation of the cycle of previous works on the development of structural, logical and mathematical models for managing an emergency situation of a terrorist nature at an object of the critical infrastructure of Ukraine, which is protected, which are intended for the development and constant implementation of procedures of an organizational and technical nature that ensure the safety of the object.
Further research will be directed to the development of appropriate mathematical models and conducting field experiments, performed using a specially designed laboratory facility to determine the reliability of the latter, comparing theoretical and practical results.
Today, there are a number of physical and chemical methods that can be used to reliably determine the signs of a fire and establish the causes of fires. Almost all of them are based on the ability to register structural transformations that occur under the influence of high temperatures and directly from the flames of fires.
The problem of obtaining objective data, necessary to establish the center of the fire and the ways of the spread of combustion, remains extremely relevant, especially in cases where it is impossible to examine the objects of the physical environment due to their destruction and removal from the fire site.
The task of determining the burning conditions in different fire zones and identifying the focal signs of a fire in yours were not set and solved. The analysis of the electrical resistance of the soot layer makes it possible to investigate the sooting of the place at the site of the fire and, thus, to identify the ways of propagation of the main convective flows and the focal zone.
