Latushkina latushkina@phti.by Olga I. Posylkina ola-gapa@yandex.ru Aleksandr G. Artemchik aleksandr.artyomchik@gmail.com Ivan A. Sechko zmey20017251@gmail.com <p><i>Purpose.</i> Study of the adhesive strength and wear resistance of metal coatings formed by magnetron sputtering on fire-proof fabric materials. </p><p><i>Methods.</i> Tribological tests were carried out on a JLTB-02 tribometer. The adhesive strength of the coatings was evaluated using a measurement technique using adhesive tape with a lattice notch. The wear tracks on the coatings were examined using a Hitachi S-900 scanning electron microscope. </p><p><i>Findings.</i> The adhesive strength and tribological properties of aluminum and brass coatings deposited by magnetron sputtering on arcelon with various impregnations are investigated. It is determined that the use of impregnation, regardless of the composition, increases the adhesive strength of coatings formed by magnetron sputtering. The influence of both the composition of the chemical impregnation and the coating material on the tribological characteristics of the studied samples has been established. It is established that aluminum coatings are characterized by lower values of the coefficient of friction and the width of the friction tracks than for brass coatings, which indicates their higher wear resistance. </p><p><i>Application field of research.</i> The presented research results can be used in the manufacture of fire-retardant overalls necessary for firefighters, rescuers, as well as for oil and gas industry workers, welders, metallurgists and the military. </p> 2022-11-16T00:00:00+03:00 Copyright (c) 2022 Latushkina S.D., Posylkina O.I., Artemchik A.G., Sechko I.A. https://journals.ucp.by/index.php/jcp/article/view/697 Promising methods for assessing the degree of thermal damage obtained under fire conditions made with the application of gypsum boards 2022-11-15T11:19:15+03:00 Andrey V. Surikov shurikoff@bk.ru Natal'ya V. Zaynudinova Zainudzinava@gmail.com Vasiliy P. Boyko pojarnik@mail.ru <p><i>Purpose.</i> To determine promising methods for assessing the degree of thermal damage to structures made using gypsum boards (hereinafter referred to as drywalls) received under fire conditions. </p><p><i>Methods.</i> Analysis of the results of existing studies and methods for assessing the degree of thermal damage to structures made using drywalls under fire conditions. Laboratory studies of samples of gypsum boards in a muffle furnace under temperature exposure. </p><p><i>Findings.</i> Based on the results of a review of literature sources, promising methods for assessing the degree of thermal damage to structures made with the use of drywalls were identified under fire conditions. The well-known method of visual assessment of drywall damage in case of fire was adapted for the purpose of its application on the territory of the Republic of Belarus. It has been experimentally established that the visual method for assessing the degree of thermal damage to various types of drywalls has low information content at certain temperature ranges. </p><p><i>Application field of research.</i> The obtained research results can be used when examining a fire site to determine the source of the fire, propagation paths, conditions and dynamics of combustion development, as well as in the development of technical means for determining the degree of thermal damage to structures made from drywall sheets received under fire conditions.</p> 2022-11-16T00:00:00+03:00 Copyright (c) 2022 Surikov A.V., Zaynudinova N.V., Boyko V.P. https://journals.ucp.by/index.php/jcp/article/view/698 Research of fluorinated surfactants for the development of a film-forming fire extinguishing composition 2022-11-15T11:19:16+03:00 Igor Yu.

Busel Mischabox@yandex.ru <p><i>Purpose.</i> To study of the dependence of the surface tension of fluorinated surfactants of various chemical nature on their concentration and determine the most suitable fluorinated surfactant for use in film-forming foam concentrates. </p><p><i>Methods.</i> The surface tension of the solutions was measured using a KRÜSS K20 automatic tensiometer using the Du Noüy ring method described in ISO 304. The determination of the critical micelle concentration of surfactant solutions in aqueous systems was carried out according to the State Standard 29232-1991. </p><p><i>Findings.</i> The results of research of the surface tension of aqueous solutions of anionic, nonionic and amphoteric fluorinated surfactants from various manufacturers are presented. The most promising fluorinated surfactants and co-solvents being used as a part of film-forming foam concentrate for fire extinguishing have been established. The choice of a fluorinated surfactant for the creation of a targeted foaming agent, which makes it possible to obtain an aqueous film on the surface of n-heptane, is substantiated. </p><p><i>Application field of research.</i> The results obtained can be used in the development of a formulation of a targeted foaming agent for extinguishing fires. </p> 2022-11-16T00:00:00+03:00 Copyright (c) 2022 Ivanov I.Yu., Navrotskiy O.D., Kondakova Ya.A., Krasavin V.E., Busel M.O. https://journals.ucp.by/index.php/jcp/article/view/699 The effect of the height of the installation of a manual fire barrel with optimal geometric parameters on the consumption of extinguishing agent 2022-11-15T11:19:18+03:00 Artem A.

The influence of the height of the location of the fire barrel on the consumption of extinguishing agent at different fire pump forces is investigated. It was found that the calculated values differ from the experimental ones by no more than 8 %, which in practice does not affect the fire extinguishing process. </p><p><i>Application field of research.</i> The results obtained are the basis for calculating the geometric parameters of the flow part of fire barrels and a comprehensive study of their tactical and technical characteristics.</p> 2022-11-16T00:00:00+03:00 Copyright (c) 2022 Morozov A.A. https://journals.ucp.by/index.php/jcp/article/view/700 Influence of the dimensions of the grid cell and the distance from it to the nozzle of the foam-generating device on the foam dispersion 2022-11-15T11:19:18+03:00 Andrey N.

Golyakova feniks_irina@mail.ru Victor A. Karpievich karpievich68@yandex.by <p><i>Purpose.</i> To reveal the peculiarities of ideas about psychological safety among the inhabitants of Belarus, taking into account their gender and age characteristics. </p><p><i>Methods.</i> To assess ideas about psychological safety, the Questionnaire for Psychological Safety was used, developed in the laboratory of the psychology of post-traumatic stress of the Institute of Psychology of the Russian Academy of Sciences N.E. Kharlamenkova with a team of co-authors. The questionnaire includes 60 descriptors that people most often associate with the concept of security. Quantitative and qualitative methods were used for data processing. </p><p><i>Findings.</i> The article analyzes the differences between men and women, as well as between the age groups of 18–31 years old and over 31 years old, in their representations about psychological safety. It was revealed that there are differences in the ideas of psychological safety in men and women. The difference between representatives of different age categories was also revealed. It is shown that in the views of men, safety is associated with control and self-reliance, and in the views of women - with support and assistance. Some data correspond to the results obtained in foreign studies. The novelty consists in the findings that for adult men, health is in the first place, while for women and young people this descriptor is several ranks lower. </p><p><i>Application field of research.</i> The results obtained can be used by specialists in the field of teaching the population the rules of life safety. Understanding the representations associated with safety among particular gender or age group will help the educators on life safety to develop classroom materials more effectively.</p> 2022-11-16T00:00:00+03:00 Copyright (c) 2022 Golyakova I.V., Karpievich V.A. https://journals.ucp.by/index.php/jcp/article/view/703 Dynamic driving simulator of fire rescue vehicle 2022-11-15T11:19:21+03:00 Ivan I.
