Research of fire hazard parameters of deeply struck extractant in a multicomponent system tributyl phosphate — diluent — nitric acid

Vasilyev A.V., Ph.D. of Engineering Sciences; Kondratyeva L.V.
FSBEE HE Siberian Fire and Rescue Academy of Firefighting Service of EMERCOM of Russia

The article provides an overview of literary materials related to explosions and fires at the reprocessing plants and caused by the formation, accumulation and uncontrolled decomposition of traces of tributyl phosphate-based extractant (TBP). The reason for such explosions was the presence in the extractant of its decomposition products — dibutyl phosphoric and monobutyl phosphoric acids (DBP and MBP). To date, the effect of DBP and MBP on the flash and ignition temperatures of an extractant based on TBP has not been determined. The article presents the method of hydrolysis of TBP for accumulation of DBP and MBP in the extractant. The process of measuring the flash point temperature and ignition point temperature of a pure extractant and extractant with different contents of DBP and MBP is described. The dependence of changes the flash point temperature and ignition point temperature on the different contents of DBP and MBP in TBP is shown.

33FSBEE HE Siberian Fire and Rescue Academy EMERCOM of Russia

The article is devoted to the issues of self-heating of oiled fibrous and porous household materials at public catering facilities. The article shows the complexity of the investigation of the causes of fires occurred from spontaneous combustion of substances and materials during the fire and technical expertise. The article presents the results of the study of self-heating of oils of vegetable origin, previously deposited on the porous surface of household materials. Revealed that the self-ignition of vegetable oils are more prone to oils with an expired shelf life. Materials based on viscose with the addition of polyester fiber have the advantages to enhance the process of spontaneous combustion with respect to other household fibrous materials.

1Siberian Fire and Rescue Academy of Firefighting Service of EMERCOM of Russia;
2FSBI «Forensic expert organization Federal Fire Service «Fire testing laboratory» in the Krasnoyarsk Territory»;
3Saint-Petersburg University of state fi re service of EMERCOM of Russia

The article describes the process of recreating the real physical environment of a dwelling and creating conditions for a fire as a result of an emergency fire hazardous operation of the electrical network and electrical equipment. The models of fire occurrence were created on the basis of practical experience in the study of real fires by specialists of the forensic institution of the FPS IPL in the Krasnoyarsk Territory, together with employees of the Main Directorate of the Ministry of Emergencies of Russia in the Krasnoyarsk Territory. The experiments carried out made it possible to reliably assess the incendiary ability of these fire hazardous phenomena, the peculiarities of the occurrence of combustion and the development of a fire due to them. The work carried out made it possible to create videos with the purpose of a visual demonstration to the population of how domestic fires can start and what consequences they can lead to. The videos were shown in early 2020 on television in the Krasnoyarsk Territory and were posted on the Internet on the popular video hosting «YouTube».

Investigation of the temperature field in mine working in the vincinity of a seat of fire during emergency rescue operations in coal mines

Agarkov A.V.
The «Respirator» State Scientific Research Institute of Mine-rescue Work, Fire Safety and Civil Protection of the Ministry of the Donetsk People’s Republic for Civil Defence, Emergencies and Elimination of Consequences of Natural Disasters

The relevance of monitoring and control of the mine environment during elimination of fires at the mining enterprises has been presented. The investigation results of the temperature field in the mine working of the coal mine in the vicinity of the seat of fire have been presented. It has been established that if the temperature behind the seat of fire does not depend much on the temperature diffusivity coefficient, then the length of the temperature «plume» before the seat of fire substantially depends on it. The dependence of the distribution of relative temperatures in front of and behind the seat of fire in the mine working of a coal mine has been presented. According to the proposed methodology it is possible to find the distribution of temperatures along the entire length of the mine working with a seat of fire. The further promising areas of theoretical and experimental studies of the unsteady distribution of fire gases along the length and cross section of the mine workings of coal mines during the accidents have been adduced.

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.

Emergency Security (05.26.02)

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.

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.

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.

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.
