How to choose a car fire extinguisher
The fire extinguisher was not a formal attribute of the picking machine and, in the case fire was able to save the machine from complete burnout, it is necessary to choose.

The fire extinguisher was not a formal attribute of the picking machine, and in the event of a fire could save the machine from complete burnout, it is necessary to choose. A vehicle fire can occur for multiple reasons: as a result of a traffic accident, malfunction wiring, leaking fuel in the fuel system, and just due to careless handling of open fire.
A modern car in case of abnormal operation of its systems and mechanisms represents a source of increased fire danger. That is why it is so important to always have in the car reliable and trouble-free extinguisher, can effectively resist the fire
General requirements of car fire extinguishers
The volume of extinguishing agent a fire extinguisher for passenger cars shall be not less than 2 l, and for trucks – 5 litre
Car fire extinguisher must have a high efficiency of localization of fires and their subsequent suppression. Type of extinguisher should be selected in such a way as to ensure safe and reliable suppression of both solid and liquid combustibles and electrical equipment under voltage.
Operating temperature range of the extinguisher shall meet the conditions of the vehicle, providing reliable and smooth operation of the extinguisher not only at positive but also negative temperatures.
Water and foam extinguishers
These extinguishers can safely say that they are both technically and morally wrong, because burning gasoline, diesel fuel or oil, abundantly present in the car, they put out simply can not. Operating temperature range of fire extinguishers based on water temperature is limited to the positive part of the scale because of the properties of water to lose fluidity upon decrease of temperature below zero.
In addition to extinguish the electrical equipment under voltage (including high voltage), it is extremely dangerous to health and life. Because of this, water and foam extinguishers as extinguishing media for car us will not be considered.
Carbon dioxide fire extinguisher
The principle of operation carbon dioxide fire extinguisher is the displacement of air around the flame and replacing it with carbon dioxide, does not support the oxidation reaction of combustion.
The positive aspect of such extinguishers is that they cool the burning surface, thus preventing their re-ignition. But sometimes the cooling effect of their use is so strong that it may lead to deformation of the head or engine block.
These extinguishers successfully cope with burning fuel, lubricants and safe when putting their wiring and electrical equipment under voltage.
Due to the fact that the temperature of the jet of carbon dioxide reaches -800 C, With inept or careless use of carbon dioxide fire extinguisher can frostbite exposed areas of the body. Their use is not allowed by firefighters inside the car, where the people are, because 10% concentration of carbon dioxide in the inhaled air may result in paralysis of the respiratory system.
Carbon dioxide fire extinguishers are subject to mandatory annual technical inspection and recharging time in 3-5 years.
dry Powder extinguisher
Located in the container of the fire extinguisher special powder pushed away from it under the action of compressed gas, covers the surface of the fire, thereby blocking the fire access to oxygen. Suitable for extinguishing all types of fires and is relatively harmless to humans. It is preferable to use powder fire extinguishers, pre-filled with a gas to displace the powder, than those in which the gas pressure is produced by a chemical reaction in the gas generating device. To distinguish them it is simple — extinguishers filled with gas, equipped with a pressure gauge.
The disadvantage of powder fire extinguishers is the difficulty of cleaning soiled powder parts of the car, especially in cases when the powder was baked. Powder cloud reduces the visibility of the fire, what complicates the localization and extinguishing the fire.
Such fire extinguishers shall once in two years to pass technical inspection with subsequent mandatory reload
Air-emulsionnye fire extinguisher
Is probably the most safe and environmentally friendly means of fire extinguishers. They can be used to effectively extinguish both flammable liquids and solid combustibles.
Without risk to life can use the air-emulsion fire extinguisher for extinguishing fire of electrical equipment under voltage up to 10 kV. Like carbon dioxide, the air-emulsion fire extinguisher cools the fire, preventing re-ignition.
This extinguisher will be uninterrupted as to work in sub-zero temperatures (up to -400 C) and in thirty-degree heat.
One re-examination and could last up to 10 years of operation, and to recharge it throughout the term of service is permitted up to 40 times.
As follows from the above, the most appropriate fire extinguisher for car is the air-emulsion.
If you acquire such a fire extinguishing means is not possible, you should equip your car with a fire extinguisher with powder or carbon dioxide. The best option would be the presence in the car and powder and carbon dioxide fire extinguishers. First, it is appropriate for the elimination of fires inside the cabin, and the second is ideal to extinguish fire in the engine compartment.
Keep a fire extinguisher in an easily accessible place interior of your car, in the event of the need not to waste precious time looking for him.
