FIRE EXTINGUISHING AND OTHER URGENT WORK IN ELECTRIC CARS

Abstract

The development of modern technologies simultaneously with the improvement of the conditions of human existence creates additional risks that had been solved to ensure the safety and comfortable conditions of people's stay. One of these areas of human development is the gradual transition to alternative energy sources and modes of transport, including electric vehicles. Modern versions of electric vehicles, by their tactical and technical characteristics, practically do not concede cars with engines of internal combustion, but the research shows that from the point of view of fire safety and tactics of firefighting, the batteries of electric cars require some other approaches and algorithms for carrying out of emergency rescue works. Considering the modern experience and experimental results of research on the tactics of firefighting of electric vehicles, it turned out that the normative intensity of water supply (aqueous solutions) should be increased and make not less than 1,2 l/(c·m2). An increase in the normative intensity of water supply requires the fire-extinguishing chief to ensure in advance the uninterrupted supply of the extinguishing agent to the fire brigade, necessarily installing a tanker truck on a fire hydrant or reservoir. The specificity of the extinguishing of electric cars also shows the ineffectiveness of the use of a fire-extinguishing agent of air-mechanical foam and the necessity of compulsory dismantling of the battery pack of an electric vehicle after the elimination of the fire. The main results of the work are summarized in the general list of the algorithm of actions of the fireextinguishing chief after his arrival at the place of the emergency related to the ignition of electric vehicles. Compliance by the fire-extinguishing chief of the given algorithm of action will minimize the risks for the personnel of the rescue unit and accelerate the elimination of the fire. Accordingly, to the analysis and scientific results, the future directions of scientific research should be aimed: at improving the algorithm of action and tactics of elimination the fire of electric cars, the development of technical devices for extinguishing the battery of electric cars, the development of automatic fire extinguishing of electric cars, the development of more effective fire extinguishing means for extinguishing the rechargeable battery of electric cars.
