The present time is characterized by the rapid development of cities and, as a consequence, the aggravation of a whole set of problems. Cities provide a fairly high standard of living for the population, satisfy their needs, but at the same time, they are the center of the significant environmental problems. All this is due to the excessive concentration of transport and economic facilities in relatively small areas. Goals and objectives. The aim of the work is to assess the level of impact of vehicles in terms of noise pollution and air pollution in Belgorod Construction of noise maps of individual microdistricts of Belgorod and calculation of emissions of the main pollutants into the air from traffic flows, which will make it possible to predict and identify areas of the urban environment where the established sanitary and hygienic standards are exceeded. Methodology. The study of the noise situation in certain areas of the city was carried out in accordance with the requirements of GOST 20444-2014 and GOST 53187-2008. The main characteristic was the equivalent sound level of traffic flows, calculated from the results of instrumental measurements of the noise level. To assess air pollution, calculations were carried out according to the methodology for calculating emissions of pollutants into the atmosphere by vehicles on city highways. Field observations to study traffic flows were carried out in the daytime. Results and its discussion. The obtained data on the noise level on the territory of the studied microdistrict were used to compile a noise map, which makes it possible to identify areas of the urban environment that do not meet sanitary and hygienic requirements for the noise factor. Calculation data for emissions of harmful substances from vehicles can be used to create environmental passports and are useful in making decisions to reduce the negative impact of transport on the environmental situation of industrial cities. Conclusion. The study of noise pollution and atmospheric air pollution, the source of which is motor vehicles, in an urban environment, makes it possible to develop a complex of health-improving, environmental, urban planning measures and a number of architectural and planning solutions aimed at reducing the level of noise pollution and air pollution in these areas.

An experimental installation with data logging based on the Arduino platform was developed to implement the approach used in modeling the spread of fire hazards in small rooms. The values of the heat flow from the convective column of the combustion center in the initial stage of the fire for a residential building with a predominant cellulose load were determined using obtained device according to the zone model of the fire. Goals and objectives. The purpose of this work is to create a compact device that allows us to quickly assess the development of fire hazards over time at the initial stage of their occurrence and to hold experiments at objects comparable in size to real fragments of buildings and premises. Methods. An experiment with the use of the field test method of fire hazard testing and an assumption about the possibility of using the developed device in testing the dynamics of the spread of fire hazards in rooms with a cellulose fire load was conducted. It is based on the data about the zonal modeling of the spread of fire hazards using modern technical means. Results and discussions. Experimental studies seem to be a necessary part of the forecast of the spread of fire hazards in residential premises. Field fire tests, which refer to tests of fragments of buildings and structures that are close in size to real objects, are able most accurately convey the conditions that occur in apartments and private homes during the fire phase. The current level of development of microelectronics makes it possible to use hardware and software for a wide range of people, including those who do not have a special education. Device, developed and created by the authors, is based on the Arduino Mega 2560 platform. It is compact and portable. It allows quickly receive and record data from the experiment of modeling fire conditions in small rooms. The obtained results allows us to estimate the level of heat flow of the convective column from the ignited wood, which simulates the fire load in the room to the ceiling, as well as the average temperature of the gas medium and the heat loss coefficient in the ceiling.

It is shown that the development of methods for modeling multicomponent risks is a promising direction for improving information and analytical support for control in security systems. The purpose of the study is to develop new approaches to the study of natural, technogenic and anthropogenic risks based on stochastic modeling of the structure of multicomponent risks in socio-technical systems. Methods of stochastic modeling are based on a matrix representation of risk components, detailing the states of the protected object and the probabilistic characteristics of the functioning of security systems. Results and discussion. A method for analyzing multicomponent risks is presented, reflecting in-depth detailing of the states of the protected object and the probabilistic characteristics of the functioning of security systems. A stochastic model has been built that describes the structure of risk as a result of the interaction of two components, a multiplier and an accelerator, associated with various elements of the model, which, respectively, determine the possibility of occurrence of dangerous events, as well as the degree of vulnerability of protected objects. A connection is established between the indicators of expected losses in a certain territory with the presence of forces, means and systems of protection against the effects of hazardous factors and their current state. The procedures for determining the main parameters of the proposed stochastic model based on statistical and expert methods are discussed. A mathematical toolkit has been created for comparative analysis of the effectiveness of measures to reduce risks in socio-technical systems. The problem of multicriteria combinatorial optimization of planned costs and distribution of financial, material, technical and labor resources in territorial security systems is formulated.

The article presents a methodically described, consistent algorithm for assessing the state of integrated safety of industrial enterprises that are classified as hazardous production facilities. A study was conducted in choosing a method that allows calculating the weighting coefficients of the estimated measures, the implementation of which is provided by services (structural divisions) performing labor functions to maintain the integrated security system of the enterprises under consideration at the required level. Goals and objectives. The main purpose of the article is to identify the causes of hazards in cases when the danger (accident or fire) occurs with the coverage of two or more departmental (industry) security subsystems that are part of the complex security of the enterprise. Reduction of hazards (accidents and fires) at industrial enterprises is carried out at the expense of resource investments directed to minimize (exclude) the conditions (prerequisites) for the occurrence of risky events that can be transformed into accidents or fires. However, due to the limitations of the resource allocated by the enterprise to ensure its comprehensive security, there is a need to identify those places (points) whose risk indicator is high (critical), requiring a response to them without delay. It is proposed to normalize each event included in the content of the checklist for checking the enterprise for both industrial and fire safety. Methods. The choice of the hierarchy analysis method is justified, the use of which, based on a pairwise comparison of factors and alternatives, allows us to determine a local priority indicator for each element under study. Results and their discussion. The algorithm of sequential actions presented in the article in the form of a detailed description allows you to set an indicator measured in the form of a quantitative value for each event held. Conclusions. An example is presented in a fragmentary form showing the order and sequence of obtaining local and global priorities, where the definition of local priorities indicates the weight of a characteristically described event that caused a hazard (accident and fire). Obtaining weighting factors in the form of global priorities is directly related to the services (structural divisions) performing labor functions to maintain the enterprise's integrated security system at the required level.

The advantages, disadvantages and some aspects of technology improvement are presented. It was explored that temperature activated water in a suspended state is able to dilute and cool the combustible medium and displace the oxygen of the air in enclosures, thereby eliminating the fire. The supply of hot water through hose lines over long distances (no more than 2 km) without loss of quality properties makes it possible to use the technology when extinguishing fires in hard-to-reach places. Low water consumption for extinguishing fires (up to 40 minutes without refueling) has a positive effect on extinguishing fires under conditions of limited water supply. The results of scientific research have been introduced into new models of appliances capable of performing a huge range of tasks set by EMERCOM of Russia. Conclusion. The information presented in the given publication will help managers and users of the technical means based on the temperature-activated water technology to apply and use it correctly for extinguishing fires and eliminating emergencies. The article discusses new aspects of the application, which allow us to suggest the possibility of extinguish fires, preventing and eliminating accidents in underground mine workings, subsurface suppression of municipal solid waste landfills, and extinguishing live electrical installations with temperature-activated water.
