The village of Staraya Tabaga in Yakutia tested a prototype of a low-cold liquid for extinguishing fires in subzero temperatures. Development of scientists of the republic and the N.E. Bauman Moscow State Technical University will solve the grave problem of extinguishing fires in winter, especially in remote communities with limited access to warm hydrants. The test results will determine the effectiveness and environmental friendliness of the fire extinguishing liquid and decide its use by the fire departments of Yakutia.
In 2020 the head of Yakutia, Aysen Nikolayev, signed a cooperation agreement with the N.E. Bauman Moscow State Technical Institute, within the framework of which it is planned to implement on a systematic basis constructive cooperation and interaction in the Scientific and Educational Center "North: Territory of Sustainable Development."
One of the areas of cooperation is creating industrial technology for obtaining a liquid for firefighting in shallow temperatures, which is energy and resource-saving, and environmentally safe. In February 2022, a prototype of a low-hardening liquid for extinguishing fires in negative temperatures was tested in the village of Staraya Tabaga.
The Arctic Research Center of Yakutia, the State Fire Department of the Republic, and the EMERCOM of Russia took part in the test. A derelict building in the village of Staraya Tabaga and 1,200 liters of liquid were used for practical tests.
As Yuri Shipitsyn, director of the Yakutia Research Center, told journalists, the liquid prototype used results from the first year of research work, which was given the name "antifire." During the year, scientists conducted a whole series of laboratory tests. They selected the chemical composition of the liquid, which would correspond to the temperature regime established by the technical specifications.
"It means that up to negative 45, it must be stable as a liquid and at the same time provide fire suppression. We all know that the republic's territory is vast, settlements are at a distance from each other, and fire stations are distant from the place of possible flame formation. Thus, the use of water in winter reduces the effectiveness of extinguishing. This problem is at the heart of this research work. The liquid must be able to withstand the cold for a long time, retain its fluid used for extinguishing, and at the same time, it must be environmentally friendly," said the head of the Arctic Research Center.
He also added that snow samples would be taken to test the environmental friendliness of the development after the trial. Perhaps the concentrations and ways of making the liquid will change in the future. The solution used in the tests was made at Baumanka and delivered to the republic by rail in December. Since January 17, the liquid was stored in containers on the street, and only today it was poured into a fire truck - that is, the development has already shown itself in terms of low pouring. The experiment conducted today should show the effectiveness in terms of firefighting efficiency.
The new development is considered with special care, first of all, by the State Fire department of Yakutia. The unit of the fire brigade No. 11 for the protection of the village of Tabaga took a direct part in the experiment - the forces of the team extinguished the fire with the help of an experimental liquid.
Anatoly Pavlov, deputy chief of the Yakutia State Fire Department, noted the relevance of the development.
"Given the climatic conditions in the republic, there are problems with fire extinguishing agents. If this development is implemented, it will effectively extinguish fires. When extinguishing fires at low temperatures, the Republic's fire department divisions face problems with freezing water in fire hoses and fire pump systems; this is especially noted in settlements with no external fire water supply reservoirs and hydrants. Based on the results of this test, the results will be summed up, according to which a decision will be made on the need to use this fire extinguishing agent by the divisions of the state fire department,” he said.
