New ideas for calculating the required time for evacuation of people and the effectiveness of using a portable filter of self-rescuers during the evacuation in case of fires. Study guide. Moscow: Academy of SFS EMERCOM of Russia, 2007, 222 p.
The analysis of toxic gases generated by the combustion of the combustible load of premises and modern building materials was performed. The influence of toxic products of combustion on the human body was studied. Standard and modern methods of calculating the required time for the evacuation of people from premises were analyzed. The determining influence of dangerous fire factors that are not taken into account in regulatory documents was shown. The existing database on fire load based on a review of literature sources was updated and expanded on the release of toxic gases. The results of calculating the order of occurrence of dangerous fire factors using the standard calculation method and an extended database were presented and analyzed. The results of the numerical calculation of the dynamics of changes in the concentrations of toxic gases on escape routes during a fire in buildings and structures using modern field and zone methods were presented. The necessity of using portable filter self-rescuers to ensure the safe evacuation of people from buildings in case of fires was justified. The monograph is aimed at researchers and practitioners of fire protection, lecturers and students of higher educational institutions of fire and technical profile.

Science
- A mathematical model for calculating the content of carboxyhemoglobin in human blood under the influence of carbon monoxide (CO) was proposed. It was developed based on the results of numerical experiments to determine the concentration of carboxyhemoglobin at an increased rate of pulmonary ventilation, characteristic of internal fire conditions.
- A mathematical model for calculating the parameters of heat and mass transfer of a spotted fire that occurs during a forest fire near an energy facility was proposed. The analysis of regulatory requirements for safe distances from power facilities to the forest edge was carried out.
- An installation for determining the fire hazard of condensed materials during their thermal decomposition was created. It consists of a combustion chamber with an electric heating radiator and a condensed material sample holder placed in it. The unit reliably detects the fire hazard of condensed materials during thermal decomposition.
https://yandex.ru/patents/doc/RU174688U1_20171026 - A device for measuring toxic factors of thermal decomposition of substances was invented. It is designed to measure: toxic factors of thermal decomposition of substances, the rate of reduction of oxygen concentration and final smoke, dangerous to humans in a fire.

In zonal mathematical model of calculation of thermogasdynamic processes of fire one of main assumptions is that the form of a convection column over a source of burning is taken in the form of an unrestricted free and convection stream. The aim of such studies is to investigate changes in the angle of semi-disclosure of a convection column in premises based on the theoretical zone model considering local distribution of the angle of semi-disclosure of the column along its height proved by the results of the natural experiment data. In this work the specified zonal mathematical model of development of thermogasdynamic processes in case of fire in which for the first time by means of the variable angle of semi-disclosure change of a form of a convection column on its height under the influence of the protecting construction elements.
