Fire safety management in the conditions of risk-based business model

Shakhov D.V.
Main Department of EMERCOM of Russia in the Republic of Tyva

The article describes the problem of the effectiveness of financial costs for ensuring fire safety of objects, taking into account the presence of threats of death and injury to people at the objects and damage to the property of an economic entity that has the full right to risk them. The search for a reasonable balance between the financial cost of providing fire protection and threats of death of the property owner and another property with unconditional implementation of measures aimed at human security, can be implemented through the development of targeted fire safety systems.

Application of risk-based activity model in fire safety management

Yakunin A.A.1; Lobaev I.A.2, Ph.D. of Engineering Sciences, Docent
1Main Department of EMERCOM of Russia in the Republic of Khakassia;
2SFA of EMERCOM of Russia

The effectiveness of the risk-based approach in the implementation of control and Supervisory measures in the field of fire safety depends on a reasonable ratio of costs for fire protection of objects and the amount of damage that can be caused by a possible fire, which allows you to significantly reduce and optimize the cost of fire protection of objects.

Approbation of computer modeling methods in the analysis of firefighting actions

Malyutin O.S.; Vasilev S.A., Ph.D.; CHuldum CH.V., CHabanov K.D., Rogov V.V.
FSBEE HE Siberian Fire and Rescue Academy of Firefighting Service of EMERCOM of Russia

The article presents the main results of experiments on computer simulation of fighting to extinguish a real fire and subsequent analysis of the model. The article describes the problems of using computer modeling systems in the fire protection of the Russian Federation. The article provides basic information about the use of the automated information and graphics system Graphis-Tactic for computer simulation of combat operations to extinguish fires. Describes the progress of the work and the main results obtained. A number of new tools are described for drawing up schemes for the distribution of forces and means of fire protection and studying fires. In conclusion, there are suggestions for further research into the prospects of using computer modeling in the study of fires.

Aproximation to dependencies amount ruins at fire in Russian Federation from age of the perpetrator of the fire

Kaibichev I.A.1, Holder of an Advanced Doctorate (Doctor of Science) in Physico-mathematical Sciences, Docent; Kaibicheva E.I2, Ph.D. of Economic Sciences
1The Ural Institute of State Firefighting service of Ministry of Russian Federation for Civil Defense;
2Ural State University of Economics

The possibilities of using Gompertz, Gompertz-Meikham, Ferhulst models to approximate the dependence of the number of deaths in the Russian Federation during fires on the age of the fire culprit are considered. It is established that this dependence is most exactly explained by the Ferhulst model.

On the issue of providing imitation protection in systems based on the use of emergency beacons

A.A. Gavrishev
FSAEI HPE NCFU

Systems based on the use of emergency beacons are considered. It is noted that one of their main disadvantages is the availability of transmitted information to an outside observer. It is established that noise-like signals are used in known systems to eliminate this disadvantage. However, most of the well-known works do not pay enough attention to the issues of providing imitation protection of these systems from spoofing the transmitted data. Taking into account the work [2; 13], an imitation protection system based on the use of emergency beacons was developed. A block diagram of the developed imitation protection system is given, and the order of its functioning is described. The developed system, unlike most known systems, can be used to identify and verify the search station for the purpose of transmitting or refusing to transmit the required information to it.

Application of KS-entropy for quantitative analysis of civil defense communication systems

Gavrishev A.A.
North-Caucasus Federal University

An experimental analysis of civil defense communication systems using the lower bound of KS-entropy, which is considered as an analog of the structural stealth of transmitted signals, is performed. Among the analyzed models of communication systems, models of communication systems based on chaotic signals have the highest lower bound of KS-entropy and, accordingly, the highest structural stealth. The model of a communication system with simple signals has the lowest lower bound of the KS-entropy and, accordingly, the lowest structural stealth. Model communication systems with noise-like signals has a lower bound of KS-entropy, and, correspondingly, structural stealth, much greater than the model communication systems with simple signals but less than the model of the communication system based on chaotic signals. It is established that communication systems based on chaotic signals are generally more preferable by the criterion of stealth for civil defense communication systems and can potentially find wider application in them.

Analysis of the experience of application of pump and hose systems in the territory of the siberian federal district

Baturo A.N., Ph.D. of Engineering Sciences; Martinovich N.V.; Malyutin O.S.; Zuev R.V.; Elfimova M.V., Ph.D. of Engineering Sciences, Docent
Siberian Fire and Rescue Academy of Firefighting Service of EMERCOM of Russia

The article provides data on the use of pumping and hose systems by fire and rescue units in the Siberian Federal District over the past three years. The analysis of the data is carried out and the shortcomings of the existing pumping and hose systems noted by the Main Directorates of the Ministry of Emergencies of Russia of the subjects of the Siberian Federal District from 2017 to June 2020. Based on the results of the analysis of the use of tubing systems, conclusions were drawn on the future development of these systems.

Investigation of a car damaged by fire after exposure to the heat of a fire during depressurization of the fuel system

VoroshilovR.F.1; Murashkevich E.A.2
1FSBEI HE Siberian Fire and Rescue Academy EMERCOM of Russia;
2Saint-Petersburg University of state fi re service of EMERCOM of Russia

The article is devoted to the features of depressurization of the fuel system of motor vehicles in conditions of low temperatures in the sharply continental climate of the Siberian region. The mechanism of destruction of fuel lines made of polymer materials as a result of reducing the elasticity of the fuel line tube under the influence of low temperatures is shown, and a method for studying the remains of the fuel line after exposure to the heat of a fire is proposed.
