Introduction. The article analyzes statistical data for the period of 2006-2018 and presents an assessment of fire hazard levels in residential sectors of the constituent entities of the Russian Federation, which were determined on the basis of an integral socio-economic indicator of fire risk. It also considers the problems of assessing fire hazard in the residential sector as in a complex social and economic systems. The purpose of the study is to determine the levels of fire hazard and build a model for managing fire risks in residential sectors of the constituent entities of the Russian Federation. Research methods. To solve the research problems, the methods of system analysis, statistical analysis, mathematical statistics, etc. were used. Research results. A number of statistical dependencies of the fire situation in the Russian Federation have been analyzed and obtained. The indicators with the most fire hazardous level in the residential sectors of the constituent entities of the Russian Federation were determined by calculation. A block diagram of a model for managing fire risks in the residential sector using the integral socio-economic indicator of fire risk (ISEPPR) is built. Conclusion. The values of the fire hazard levels obtained in the work and the model of fire risk management in residential sectors of the constituent entities of the Russian Federation make it possible to improve management decisions in the field of supervisory activities and preventive work of the Federal State Fire Supervision Authorities. Keywords: residential sector, integral socio-economic indicator of fire risk, risk assessment, level of fire hazard

Introduction. When training fire safety specialists, it is practically important to acquire skills in assessing the fire hazard of accidents with the release of flammable gases (GG) and vapors of flammable liquids (FL). The task of detecting hazardous concentrations of these substances is performed by gas analysis systems, the main element of which is gas analyzers. Goals and objectives. The aim of the study is to create a gas analysis installation for determining the main metrological characteristics of gas analyzers in a training laboratory. The tasks include the analysis of an existing installation that complies with the current standard, consideration of the design of the test chamber and the methodology for its application for the study of gas analyzers with a diffusion supply of the analyzed medium. The methods include system analysis and mathematical assessment of physical processes occurring in the test chamber during the preparation and conduct of research. Results and discussion. The article proposes and substantiates the design of a laboratory facility, in which a given volumetric concentration of the explosive substance under investigation is created in a special chamber with the help of a dispenser. Mathematical expressions have been obtained to determine the required amount of flammable liquids. The method of preparation of the installation and options for its use for laboratory work are considered. This technique is simple and ensures the safety of industrial gas analyzers research. Conclusions. The article substantiates the design of the gas analysis unit using a special chamber as a source of the gas mixture (GM). A mathematical model of the formation of HMs with a given volumetric concentration of flammable liquids vapors is obtained, based on the Mendeleev-Cliperon equation. The technique of preparing a chamber for determining the metrological characteristics of gas analyzers in a training laboratory is considered.

Introduction. The article provides an overview of the existing approaches to solving the problem of combustion of substances and materials, for their adequacy in determining their fire hazard of products and objects. The relevance of the work is due to the need to move from latent forms in determining the fire hazard of materials and products made from them (degrees of fire resistance, flammability groups, groups of the effectiveness of fire retardant coatings, etc.) to analytical forms describing the processes in the combustion theory. Problem statement. The task of the research is to determine the relationship between the theory of combustion of substances and materials and to assess their fire hazard in natural and man-made systems. Theoretical part. The system analysis of solutions to the combustion theory problems is performed. Its results became the basis of probabilistic-physical and entropy approaches, as well as proposals for changing standards designed to provide protection from fires. Conclusions. The results of the study showed the need to revise empirical approaches in assessing the fire hazard of materials and products made from them, which includes using thermoanalytic and acoustic methods and means.

The article is devoted to the assessment of potential investment risks of the pharmaceutical company “R-Pharm” JSC with the aim of identifying the highest priority risks and developing methods for minimizing them. The relevance of the study is determined by the fact that the pharmaceutical business is characterized by a high degree of social orientation and annually invests $ 140 billion in the development of production and research, which determines the need for a risk-based approach to ensure the return on investment. The subject of this article is the investment risks of pharmaceutical companies, and the subject of research is the domestic pharmaceutical company “R-Pharm”. In order to assess the potential investment risks of “R-Pharm” JSC, the authors used elements of simulation modeling and system analysis. The proposed methods to minimize key investment risks are aimed at improving the efficiency of investment activities and is recommended as an element of the strategic planning of the company.
