For smooth operation, as well as effective and safe maintenance and repair of fire trucks, air compressors are used in fire and rescue units of the federal fire service of the State fire service of EMERCOM of Russia. The air piston compressor allows you to create the necessary air flow pressure for the operation of the pneumatic tool. Therefore, an urgent issue is the choice of a compressor model with optimal parameters. The paper evaluates the technical parameters of compressors by the method of expert evaluation. Based on the results of the assessment, the most significant parameters affecting the reliability and efficiency of the compressor were determined, and optimal models of reciprocating compressors for staffing maintenance posts of fire and rescue units and repair and technical centers were proposed.

The article is devoted to the existing international problems of improving the process of coordinating the humanitarian response to UN emergencies. The analysis of the need to conduct a study on the prospects for further improvement of the UN humanitarian emergency response coordination system has been carried out. It is reflected that, by their nature, humanitarian problems can arise unpredictably and have negative consequences, including for the population, material and cultural values. It is concluded that the urgent need of the world's states to receive international humanitarian assistance is the main incentive for the development of the UN humanitarian emergency response coordination system. The main factors influencing the improvement of the humanitarian response coordination system have been identified. The implementation of the principle of humanism aimed at the comprehensive realization of the life support of the affected population, in which the most important role belongs to States with preferential economic opportunities, is determined. The decisive role of using international experience in the use of national emergency response services of individual states is reflected, taking into account the specific features of the training of management bodies, forces and means, as well as in accordance with the requirements of regulatory legal regulation in the prevention and liquidation of emergency situations. The main directions of improving the system of coordination of humanitarian response to the UN emergency are proposed.

The article is devoted to the consideration of issues related to the design of electric motors and the use of submersible electric machines in the marine environment on drilling rigs and platforms. The article describes the calculation of parameters and energy characteristics of asynchronous electric motors of submersible electric machines. The mathematical apparatus for calculating the energy characteristics and short-circuit current of asynchronous electric motors of electric machines of open design is given. Some characteristic features of calculating the energy characteristics and short-circuit current of asynchronous electric motors of electric machines of open design, taking into account the efficiency coefficient in relation to the useful power consumed and the total losses in them, are also considered.

The article considers the problems on organization of safety of the population and fire-fighters-rescuers as a result of forest fires in the Arctic zone. It is connected with the scale and long-distance spread of forests, as well as with the conditions of harsh climate. On the example of the Republics of Karelia and Yakutia the statistics of forest fires for the period of the last six years is given. On the basis of the analysis of statistics of forest fires and causes of their occurrence the recommendations on increase of safety of the population and fire-fighters-rescuers at carrying out of actions on localization and liquidation of forest fires are formulated. They are reduced to strengthening of grouping in regions of the Arctic zone, improvement and equipping with modern technical means of protection and specialized equipment adequate to climatic conditions of the region, means of emergency evacuation of rescuers from critically dangerous zones.

The following are considered:  principles and means of ensuring the security of a corporate network, as well as features of virtual private networks that provide reliable protection and secure data transmission;  principles and measures to ensure the security of the corporate network, as well as the types of information protection provided by these security measures;  virtual private networks (VPNs) that provide a secure encrypted user connection to the network. Using a VPN provides reliable data protection, masking the user's geolocation, access to regional content and secure data transfer;  systems for detecting and preventing network hacking threats, among which the main focus is on the Kali Linux software package, as well as features of the Windows subsystem for Linux and Windows network monitoring tools;  Windows network monitoring tools, including utilities that work in console command-line mode and allow you to check the availability of remote personal computers and diagnose the connection. The Kali Linux software package is a distribution package for the Linux operating system that has more than 600 preinstalled network penetration testing programs. Among the features of the package, the article discusses the search and exploitation of network vulnerabilities, checking the correct configuration of the SSL certificate and open ports, tracing the data transfer route, checking the availability of servers and searching for network problems.

The article is devoted to the theory and practice of diagnosing fire and emergency modes of operation of piston engines with neutralizers as part of vehicles with electronic and digital control of fuel supply processes. The concept of the work is multidisciplinary, updated on the analysis of problems of global environmental sustainability, fundamental and applied research on the kinetics and energy dynamics of the generation of useful and flammable excess heat in engines and neutralizers during the combustion of fuel hydrocarbons. Gorenje The paper proposes a diagnostic method based on instrumental gas analytical control of the exhaust gas composition of a piston engine in the free acceleration mode and the use of multiple regression equations for the relationship of the exhaust gas composition with fuel supply parameters.

Reliable energy supply to military consumers directly affects the security of the country. That is why it is necessary to develop an energy system that would meet the requirements of new realities. 
 One of the main tasks facing the Armed Forces of the Russian Federation is the protection of State sovereignty and the preservation of security in the Arctic zone. In order to maintain the combat capability and combat readiness of a military facility, it is necessary to provide it with fuel and energy resources in a timely manner. The issue of optimizing the operation of boilers is relevant today and requires the search for new solutions. This methodology takes into account criteria of different types: periodic (cyclic) and random. All factors have varying degrees of influence on the choice of the optimal strategy for optimizing the operation of an energy facility. As optimization measures, the methodology considers the expediency of converting boiler houses from diesel fuel to gaseous fuel.

Renewable energy resources related to hydroelectric power supply a large part of the electricity in the world. In the hydroelectric power method, the energy of water flowing is converted into electricity. This method is considered a renewable energy resource because the water cycle is uniformly continued with sunlight. One of the first hydroelectric power applications was in grain milling, while today, modern hydroelectric power plants use turbines and generators to produce electricity. This paper is aimed to investigate the influential factors in the performance of all types of hydroelectric power turbines. Electricity generation through the thermal energy conversion process has special features such as non-polluting the environment, good efficiency, cheapness of ocean power, etc.
