Introduction. The article presents the results of many years of research in the field of organizational design of emergency and rescue services (E&RS). The study is a complete solution to the actual scientific and technical problem of substantiating and designing the most important subsystem of the infrastructure of modern cities and territories – the E&RS, which ensures the sustainable and safe life of any city (or territory). The main stages of the research are briefly considered in the article. Based on their results, dozens of publications have been published in different countries of the world. The purpose of the study is to summarize the scientific research that forms the methodological basis of the theory of organization and management of the E&RS of cities and territories. Research methods. Methods of mathematical statistics, probability theory, system analysis, mathematical modelling. Results and its discussion. The article summarizes scientific approaches to the design and organization of urban E&RS based on the use of mathematical and simulation methods. The analytical models presented in the article adequately describe the process of functioning of the E&RS in time, based on the main temporal characteristics of the response of E&RS to a random destructive event (fire, accident, accident, etc.). Simulation modeling technologies make it possible to reproduce the process of E&RS functioning in time and space, taking into account the geographical features of the region and the corresponding laws of the probability distribution of a random variable. An interesting scientific task is to determine the optimal number of basic and special fire trucks in order to ensure the constant readiness of the E&RS to respond to destructive events, which can be solved using the tools of the E&RS organization theory described in the article. Also, the article presents a brief historical overview of the formation and development of the organization theory E&RS. Conclusion. The article presents a complete multi-aspect review of scientific approaches to the design and organization of E&RS and also describes the methodological basis of the theory of E&RS organization. The presented results of multi-year research could be considered as a methodological guidance for assessing the functional parameters of any city E&RS and developing a project for its improved structure. Keywords: fire service, emergency and rescue services, statistical analysis, mathematical models, modeling. •

Introduction. The process of operation of fire trucks is investigated. A graph has been constructed that reflects the possible states of the car depending on age. A mathematical description of the possible states of the car is given and the well-known Bellman equation is adapted to describe the function of minimizing the cost of maintaining fire trucks. An algorithm has been developed that describes the conditions for the stay of fire equipment in the category of operation, which ensures the possibility of its use for its intended purpose. Goals and objectives of the study. The goal is to manage the readiness of fire trucks by defining a strategy for their operation and improving the quality of service and repair. To achieve the goal, the tasks were solved to determine the conditions for the stay of a fire truck in the I or II category of operation, a mathematical description of these conditions and an algorithm for the stay of the vehicle in the required category of operation were given.

Introduction. Over the past decades, the sphere of wooden house construction has been undergoing revolutionary changes in relation to the development of large-scale construction using wood-based structures. In this regard, one of the first places is the direction associated with ensuring the fire-safe use of such structures in the construction of buildings and structures of various functional purposes. An important sector of this direction is various types and methods of fire protection for wood, materials and structures based on it. The lack of systematic research on these issues hinders the development of effective technical solutions for fire protection of wooden structures. Goals and objectives. Identification of priority areas for research in the field of fire protection of wood, materials and structures based on it. Development of effective flame retardants that can have an impact on reducing fire danger and increasing the fire resistance of wooden structures. Determination of the influence of various flame retardants on the intensity of the process of heating and charring of elements of wooden structures in conditions of fire exposure (fire). Methods. A standard muffle furnace of the SNOL type was used as a test installation with the possibility of one-sided radiation thermal effect on the sample surface and a uniform temperature increase in the furnace up to 1200 С. The muffle furnace was upgraded taking into account the horizontal fixing of the sample on the outer panel of the furnace. To measure the temperature by the thickness of the sample, a set of thermoelectric converters of type K (chromel-kopel) with a junction diameter of 0,8 mm was used. Results and their discussion. Based on the results of theoretical and experimental studies, the main directions of research on the possibility of using various methods and types of fire protection to achieve the required fire hazard characteristics and fire resistance of wooden structures were determined. During the study, the analysis of such characteristics of charring as the rate of charring, the thickness of the charred layer was carried out. Conclusion. The research results show the possibility of certain classes of flame retardants, intumescent and heat-protective materials not only to influence the intensity of the process of charring wood, but also to affect the properties and structure of the charred layer, as well as the intensity of heating of the inner layers of wooden structures. Key words: fire resistance, fire resistance limit, fire hazard, charring, heating intensity, flame retardant efficiency, wood, wooden structures, flame retardant coatings, flame retardants.
