A.P. Savin, Ph.D. of Pedagogic Sciences, docent; S.P. Cherniy, Ph.D. of Pedagogic Sciences, docent
FSBEE HE Siberian Fire and Rescue Academy EMERCOM of Russia

The study of prospective safety hazards is primarily associated with information technology, and as a result with virtual reality. Nanotechnologies are increasingly entering our life; the question of their danger naturally arises. The advent of artificial intelligence, artificial consciousness, 3D-printers, laser devices, and robotics will change our lives in the future. They bring us dangers that we haven’t known yet.

FSBEE HE Siberian Fire and Rescue Academy EMERCOM of Russia

The paper provides an overview of different pump-hose systems computation methods in fire service. Emphasis is placed on approximation features of using methods. Declared concepts of straight and reverse pump-hose systems computation methods. Marks specific for each of them pros and cons. Making detailed overview of straight computation method and taking comparative analyze of complex pump-hose systems computation with different methods results. Especially marked pump-hose correct calculation practice significance from point of view of its effective construction and safety work. In the end of paper making conclusion about special software for pump-hose systems computation based on described methods development necessity and although about necessity to pay attention for correct construction and computation of them during fire service employee professional education process.

Biotesting in assessing environmental risks on fires

Yu.N. Koval, Ph.D. of Biological Sciences
FSBEI HE Siberian Fire and Rescue Academy EMERCOM of Russia

Many extinguishing agents are synthetic in origin, and when bound to combustion products when extinguishing fires can have a negative impact on the environment [1]. In order to study the qualitative effects on living organisms, the toxic effects of frothers on test objects were evaluated. As an object, the use of small duckweed is suggested It has been established that the development and growth of seedlings of test plants directly depend on the degree of toxicity of water. At this stage, the results of the experiment without special expensive equipment.

Justification and optimization of the formulation of hardening foam to improve the stability of buildings.The study of different compositions and methods for producing fast-hardening foam. The method and devices of its implementation for the production of mechanical-chemical foam fast-hardening foam of low and medium multiplicity are developed, the formulation for the production of fast-hardening foam for filling hollow structures of buildings and structures is justified. To reduce the combustibility of the foam, it is proposed to reduce the degree of dispersion of the combustible component or filling the foam with a stable non-combustible component.

Numerical determination of the quantity of melting drops at a single-phase short circuit

Yu.S. Kozlova
FSAEIHE «South Ural State University (national research university)»

A single-phase short fault is one of the frequent types of overhead power lines unbalance. The resulting currents can cause fires. Break-sparks (melting drops) grad to heat source that have a high ignition ability and can become an ignition source. Existing assessment techniques do not allow taking in account various electrical network parameters on the fire hazardous parameters of molten metal droplets determining. At the same time, the dependences of the number and melting drops size on the short-circuit ampere, the short-circuit duration and etc. are necessary to understanding of the ensuring fire safety process in electric power lines. The mathematical model of the melting drops formation for wires of different cross sections based on the results of the experiment and using the experiment planning theory is obtained.

Study of the dependence of the consequences of fires on the risk category of objects of protection

E.V. Bobrinev, Ph.D. of Biological Sciences, Senior Research Officer; E.Yu. Udavtsova, Ph.D. of Engineering Sciences; A.A. Kondashov, Ph.D. of Physico-mathematical Sciences
FGBU VNIIPO EMERCOM of Russia

The problems of classification of objects of protection to risk categories are considered. It is shown that the direct application of the proposed criteria in the classification of the object to a certain category of risk may not reflect the real consequences of a fire. It is concluded that it is impossible to leave without supervision objects classified as low risk, which employ a larger number of the population, as they are not provided in due measure the safety of people. The potential risk of harm to health at these sites exceeds 10-6. A proposal was made to adjust the criteria for classifying objects of protection as risk.
