Introduction. The issues of the operability of fire alarm systems at housing facilities are considered. Regulatory requirements and the results of scientific research on the functioning of these systems are analyzed. The results of assessments of the effectiveness of fire alarm systems actuation at housing facilities are presented, taking into account their characteristics for the period from 2016 to 2020. Goal and objectives. The purpose of the study is to investigate the effectiveness of fire alarm systems in houses and apartment buildings. The objective of the study is to identify the features of the functioning of fire alarm systems at housing facilities, taking into account their characteristics. Methods. Two options for assessing the effectiveness of fire alarm systems are considered. The first one is based on identification of the number of cases of implementation of various modes of functioning of fire alarm systems. The second one is based on taking into account the social consequences of fires. Results and discussion. Evaluation of the operability of fire alarm systems showed that the efficiency of fire alarm systems for houses is 83,1 %, for apartment buildings - 75,7 % on average, for the period from 2016 to 2020. At the same time, the highest value of the response efficiency (86,4 %) is observed for apartment buildings with more than 25 floors and for houses of I degree of fire resistance (82,4 %). The number of people injured in fires per one fire for houses is much less in conditions when the fire alarm systems operated signaled (0,4 people per fire) compared to conditions when these systems did not fulfill their task (0,75 people per fire). Conclusion. Compared to the period 2005-2012, the effectiveness of fire alarm systems in the residential sector has increased significantly. On average, the level of performance by fire alarm systems was 83,1 % for houses and for apartment buildings - 75,7 % for the period from 2016 to 2020. Keywords: fire, housing stock, houses and apartment buildings, fire alarm, operability, efficiency, number of storeys, fire resistance, statistical data, fire accounting card

Introduction. Extinguishing fires in remote areas of rural areas of the Republic of Sakha (Yakutia) is carried out not only by the State Fire Service, but also by volunteer fire brigades. The most important problem in extinguishing fires is the lack of fire stations in all rural settlements, which negatively affects the timely extinguishing of the fire. The problem that firefighters face when extinguishing is also considered. This is a shortage of water in the winter period of the year. Goals and objectives. The purpose of this article is to systematize the work of volunteer fire brigades (DPD), to give a clear idea of the significance of this formation. To achieve this goal, it is necessary to solve the following tasks: firstly, to describe the work and tasks of the organization of a volunteer fire brigade, and secondly, to assess the availability of knowledge, skills, and weapons with which the DPD can effectively affect the extinguishing of a fire. Methods. Volunteer fire brigades in the Far North with a shortage of water can use a method of mechanical impact on flames. Mechanical impact is understood as procedures aimed at limiting the spread and extinguishing a fire. Results and its discussion. To date, the formation of volunteer fire brigades in the regions of the Far North is developing, they focus on preventive measures to protect against fires, on rapid response and elimination of fire. Conclusions. A volunteer fire brigade (DPD) for settlements where there is no fire station is a rescue from fires and fires. The DPD can either independently participate in extinguishing a fire, or help the state fire service in extinguishing it. The DPD performs the same functions and tasks as the state fire service. The DPD has the means to cope with small fires. To extinguish large fires, DPD requires funding, which can be provided by entrepreneurs of the village, local residents, as well as the municipality of the district.

Introduction. The prospects for the construction of tanks with a protective wall of the "glass in a glass" type are due to the possibility of their use with increased safety requirements, in particular, when designing near residential areas or water areas. However, previous studies on the retention of fluid flow by a protective wall during the destruction of the internal reservoir have shown that in order to completely retain it, the wall height must be at least 10 % higher than the original liquid level in this tank. It is obvious that the construction of such high protective walls is economically impractical, while conditions can be created for the formation of zones of explosive concentrations both in its inter-wall space and behind the protective wall. In this regard, studies on an effective way to reduce the height by protecting the wall at the maximum level of filling the internal tank with a flammable liquid are relevant. In particular, it is proposed to consider the possibility of arranging on the protective wall an inclined wave-reflective visor facing the wall of the main tank. Goals and objectives. Experimentally prove the possibility of reducing the height of the protective wall of tanks with a protective wall of the "glass in a glass" type by arranging inclined wave-reflective visor on it. Obtain an empirical formula for finding the minimum height of the protective wall depending on the geometric parameters of the main tank, the interwall distance and the outbound length of the wave-reflecting visor. Methods. In the process of research, the methods of similarity theory and hydraulic laboratory modeling, physical experiment, observation, comparison, finding an empirical dependence based on mathematical processing of experimental data, description, generalization were used. Results and their discussion. It has been experimentally proven that the arrangement on the protective wall of inclined wave-reflective visor is an effective method aimed at reducing the height of the protective wall to or below the maximum level of flammable liquid in the main tank. An empirical dependence is obtained to find the optimal ratio between the outbound length of the wave-reflective visor and the inter-wall distance for the main tanks with a protective wall of the "glass in a glass" type, the nominal volume from 700 to 30000 m3. Conclusion. The proposed method of reducing the height of the protective wall and empirical dependence can be the basis for the development of the relevant provisions of the regulatory document on ensuring fire safety of tanks with a protective wall of the "glass in a glass" type, as well as used by design organizations to find optimal solutions for the design and placement of the types of tanks in question at production facilities. Keywords: "glass in a glass" tank, destruction, protective wall, inclined wave-reflective visor, laboratory modeling.
