HOW TO CHOOSE A FIRE EXTINGUISHER FOR A CAR?
A fire extinguisher in the car is another active safety system. Your safety and your property. The cost of this property on wheels is often very high, and health and life are priceless! Quite often it is possible to observe a situation when the driver unsuccessfully tries to put out a car on fire, with a cheap aerosol or powder fire extinguisher purchased for passing inspection. Motorists who volunteered to help with such fire extinguishers are also convinced of the inefficiency of cheap fire extinguishers. The result of such savings is a burned-down car and damage in the tens or even hundreds of thousands of rubles.
When choosing a car fire extinguishers, you should pay your attention to the indicators that coincide with those we pay attention to when choosing a car.
Technical characteristics of fire extinguishers:
On the modern market of primary fire extinguishing agents, there are many manufacturers offering different types of fire extinguishers, markedly different in their characteristics, quality and price.
A car fire extinguisher, in accordance with statutory regulations, must have a fire extinguishing agent (TSS) volume of at least two liters;
a fire extinguisher for a car must effectively deal with the sources of ignition of solid combustible substances (class A), liquid combustible substances (class B) and be able to extinguish electrical equipment under voltage (class E);
about the effectiveness of a fire extinguisher say ratings on the label. The higher the number next to the fire class, the greater the area or volume that can be extinguished with this fire extinguisher;
it is necessary to take into account the characteristics of the operating conditions of the car fire extinguisher and pay attention to the operating temperature range, the wider this range will be the better;
pay attention to the service life and frequency of verification and re-examination of the fire extinguisher, as well as the date of its manufacture.
There are a few nuances that you just need to pay attention to before choosing a fire extinguisher for your car.
Not all types of fire extinguishers are suitable for extinguishing a vehicle.
Aerosol fire extinguishers, more like a can of air freshener or shaving foam, due to the low efficiency and low charge of the extinguishing agent, are absolutely not suitable for extinguishing a car.
Water and air-foam fire extinguishers should not be used to extinguish electrical equipment under voltage, and high-voltage equipment is in the automotive electrical circuit.
Fire extinguishers OV and ORP are not suitable for extinguishing liquid combustible substances (class B). In addition, these fire extinguishers have a narrow operating temperature range from +5 ° C to +50 ° C, in winter, at a temperature below 0 ° C, the fire extinguisher may not only fail, but also lose its tightness.
Widespread powder fire extinguishers (OP) are free from these disadvantages, but they have other "features":
fire extinguishing powder in the process of quenching the engine compartment, leaves it difficult to remove the formation of high-temperature caked powder and engine oil.
high smoke pollution and a significant reduction in the visibility of the focus due to the powder cloud formed when using a powder fire extinguisher makes it difficult to localize the focus.
when extinguishing with fire extinguisher OP, there is no cooling effect and the probability of re-ignition is high.
The complete absence of traces of extinguishing and cooling effect is in carbon dioxide fire extinguishers (DU). Moreover, it is so strong that it can cause thermal deformations, such as a head or engine block, and frostbite of hands due to inept use of a carbon dioxide fire extinguisher.
Air-emulsion fire extinguishers OVE - environmentally friendly and safe , are devoid of the above disadvantages and have a high efficiency of extinguishing solid combustible substances and combustible liquids (class A, B). Can extinguish electrical equipment under voltage up to 20 000 V (class E). Air-emulsion fire extinguishers provide effective cooling of the hearth of combustion, significantly reducing the likelihood of re-ignition. Secondary damage from exposure to extinguishing agent air-emulsion extinguishers - minimal. Extinguishers EIA permit operation at negative temperatures down to minus 40 ° C . Long life of a fire extinguisher without reloading and re-examination is 10 years ! Allowed40 recharges of a fire extinguisher for the entire service life.
car fire extinguisher
According to the combination of characteristics, universal high-performance air-emulsion fire extinguishers OVE, the most suitable for the definition of a modern car fire extinguisher.
Reliability: All self-respecting manufacturers of fire extinguishers provide a guarantee for their products. On average, operational efficiency is guaranteed for one year from the date of manufacture. Therefore, when buying, you need to carefully examine the date of manufacture. Fire extinguishers OVE - Russian manufacturer Rusintek provided a guarantee of two years from the date of sale to the consumer.
Durability or lifetime of fire extinguishers
Powder fire extinguishers (OP) are subject to annual re-examination and mandatory recharging every two years. In addition, during storage, fire extinguishing powders are prone to caking and clumping and, at the right moment, the powder extinguisher you have hoped for can be very strong. The situation is even more aggravated if the powder fire extinguisher is equipped with a gas generating device.
All carbon dioxide fire extinguishers must undergo mandatory annual technical examination and recharge every 3-5 years.
Air-emulsion fire extinguishers of TD Rusintek LLC do not require recharging and re-examination within 10 years. The consumer only needs to periodically inspect the fire extinguisher and follow the pressure indicator arrow.
Can a fire extinguisher, whose help you expect, let you down?
Unfortunately it can. A fire extinguisher is just a tool or, if you will, a weapon for fighting fire. It should be located in the zone of direct accessibility, and not to lie in the trunk, where the sense of it will be zero, since in case of fire, the car goes for seconds and access to the trunk can be difficult when you hit it from behind. It is important to remember that even an effective, expensive fire extinguisher in your car can cause an accident, or a serious injury in an accident, if it is RELIABLY not secured in the cabin. The owner of the car needs to know the capabilities of the fire extinguisher, its features, learn in advance the instructions on the use of the fire extinguisher. For example, when using a carbon dioxide fire extinguisher, the socket and the fire extinguisher case are strongly cooled, which can lead to frostbite of the hands.
An inexpensive powder fire extinguisher of doubtful quality by an unknown manufacturer or a powder fire extinguisher equipped with a gas-generating device, which, due to the lack of a manometer, motorists buy for inspection, may simply not work at the right time. The consequences can be very bad.
PCP-geek chooses AirBow
Geek - forever, geek - in everything ... I have repeatedly stated that geeks have their own mission, that they are at the cutting edge of progress and they decide which promising technologies are eligible for further development, and which ones will die out, and not becoming a mass product. And this concerns not only smartphones, headphones, and other highly technological hni, about which I usually write reviews, but in general everything that I use and that interests me. And in particular - PCP pneumatics
PCP pneumatics is already a hobby for enthusiasts. The usual "arrow on the bottle" enough and spring pneumatics, such as the standard "fracture." The "regular shooter" will not bother with pumps and cylinders for reloading tanks. These exquisite perversions are the “privilege” of users of expensive PCP rifles, the average price of which is higher than the price of the flagship smartphone. But even among this “elite” you can stand out and demonstrate your “geekiness” if you are the owner of Crosman Benjamin Pioneer Airbow .
AirBow is a pneumatic bow, although, as for me, its more fair definition is “PCR-crossbow”. Arrows that are launched using the AirBow are shorter than usual and are closer to the crossbow bolts in the structure of the shank, so this is more of a crossbow rather than a bow. Well, the “PCP” because the AirBow design is based on the design of the PCP rifles, the same type of pneumatics is used, and if you look at the AirBow variants that are on the market, most of them either have PCP analogs, or this rifle, capable of shooting both bullets and arrows.
a typical example of an FX Airguns Verminator Extreme with a quick-change barrel. It can shoot both bullets of different caliber and bolts. In general, the Swedish firm FX Airguns is the very leader on the PCR-crossbow market. Almost all models of PCP-rifles manufactured by her have modifications for shooting with bolts. And this is cool ... They also produce the best in my opinion model of a PCR crossbow on the market - FX INDY ARROW with an integrated pump. This is generally space ... No need to bathe with pumps and balloons, put a crossbow on your knees disappoint a bit and you can shoot further.
However, the production of Swedes from FX Airguns is not only the most advanced and best, but also expensive: the prices for the same FX INDY ARROW in the minimum configuration start from € 2000, so I chose the Crosman Benjamin Pioneer, which can be bought for only € 800 ! True, there is one Zapara. If, after a small modification, you can shoot ordinary aluminum bolts from the PCP crossbows produced by FX Airguns, the price of which on AliExpress is only € 2 per piece ... There you just have to pick out the plastic shank of the bolt, then with Crosman Benjamin Pioneer this trick will not work
For shooting with the Crosman Benjamin Pioneer, branded carbon arrows are used with a special shank, which serves as a lock, and they cost ... drum roll ... Already € 80 for a set of 6 pieces ... And this is still with a discount. So I highly recommend not to shoot twice at the same target. The accuracy of the Crosman Benjamin Pioneer is such that you can make a “Robin Hood” (shot an arrow at an arrow), and then both bolts can be thrown away. It is also not recommended to shoot targets that are not intended for shooting from a crossbow, for example, a tree ... The power of the Crosman Benjamin Pioneer VVVA is “beyond your expectations”, so the bolt either flies through, losing its plumage, or gets stuck so that without damaging, almost impossible.
Who would have thought that the power and accuracy of a crossbow could suddenly become a problem ... Well ... Of course, if you are ready to pay 15 € for a bolt, plus 80-150 € for special self-healing targets for crossbows, then there are no problems. The problem with “Kach” for the filling of a PCP tank with compressed air is solved exactly the same way. Although, like it or not, this is a real zapar ... PCP tanks can be “filled” with a hand pump, which is long and difficult physically. The working pressure of the Crosman Benjamin Pioneer tank is 200 Bar (it is even less than the standard PCP rifle), but to get it, you need to “pump” the pump 120-150 times. After this "exercise" it is difficult to immediately start shooting accurately. Yes, and completely "pumped" PCP-tank is only enough for 8 shots ... So with a manual pump will have to "pump" a lot and often ...
