FIRE! FIRE!

Margaret Thatcher said: "90% of our concerns are about what will never happen."

Mikhail KOLODOCHKIN

Indeed, fires are often shown on TV, but that in my car or in my garage - it can't be! What is a sin to hide - in the vast majority of cases, fire extinguishers are really not purchased for themselves, but for the inspector. Nevertheless, even in this case, you should not buy a pig in a poke.

If you want to buy a fire extinguisher primarily for the "excuse" from the corrosive traffic police inspectors, then …

… pay attention to photo 1. Aerosol products of this type have a number of undoubted advantages - they are inexpensive, compact and pretty (this is also important!). Unlike his "serious" colleagues, this "handsome" can always be at hand - both for presentation to the inspector, and for intended use. The kid is really able to extinguish the fire, but he cannot jump above his head - his stream is small, and even short-lived. Therefore, it is somewhat reminiscent of a gas gun - a good thing, but it will not help against a bandit …

If you really want to meet the fire fully equipped, then …

… go in search of "weapons." Do you like carbon dioxide or powder?

Carbon dioxide? Well, this is a worthy choice - they can pay off almost everything, even electrical wiring under voltage up to 10, 000 V! The only thing it can’t cope with is substances that burn without air (potassium, aluminum, magnesium, etc.). The products are almost all-weather and can operate at temperatures from -40 to + 50 ° C, and they need to be recharged once every 5 years. The health check of carbon dioxide products is carried out by weighing, that is, as a rule, “by eye”. If the piece of iron is heavy, it means it keeps pressure, but if you feel better, you need to take action.

A carbon dioxide fire extinguisher is a weapon for a real man! During the “attack”, the liquid acid escaping from the cylinder with a pressure of under a hundred atmospheres roars heartbrokenly, filling the enemy with snowy porridge … By the way, the temperature of this porridge is about minus 70 ° С, so take care of your hands …

Everyone chooses a suitable size for himself, for example, at Pozharsky … sorry - at Pozhtehniki in Torzhok (photo 2). For cars, a volume of several liters is quite enough, and garages and warehouses should have something more serious in the arsenal. Taking this opportunity, we express our surprise to the creators of the OU-40 monster (see the screensaver). Have you guys ever tried transporting your creation? The flimsy handle falls off, a single wheel tucks and all 160 kg fall with a roar to your feet … Well, our photographers are used to everything, but if you really have to put out something?

Carbon dioxide fire extinguishers are great for offices. The fact is that after a while the “porridge” mentioned above completely evaporates, leaving no trace of the “Mamaev invasion”. Unfortunately, this advantage sometimes turns out to be a drawback - when wood coatings catch fire, they tend to smolder for a long time, and therefore the possibility of new incidents is not ruled out.

And another advantage of carbon dioxide products - practice shows that they … do not steal!

From liquid to gaseous! If the designation of a powder fire extinguisher contains the letter Z, then we have before us a product of the injection type. In other words, gas (air, nitrogen, carbon dioxide) with a pressure of up to 16 atm is pumped into such a fire extinguisher.

Powder injection fire extinguishers (photo 3) almost do not differ from carbon dioxide in their abilities - they can extinguish the same under the same conditions. However, they are more compact and lighter than their colleagues. Evaluation of their performance is carried out not by external inspection, but by a pressure gauge installed on the head of the product. Burns are excluded: the outlet stream has a normal temperature. Moreover, in appearance, it resembles what happens when you hit the wall with an empty flour bag … Hence the disappointing forecast - after putting out the fire, general cleaning of the room is waiting for you … But you can’t be afraid of tree decay - powder with this will cope.

Photo 4 shows powder fire extinguishers of various types - next to the injection one there is a product with a gas generating element. This design has both pros and cons. It is convenient to use unified fire extinguishers as an automatic fire extinguishing system: in case of fire, they fire independently, but “think” for quite a long time - up to 5 seconds. When reloading, there is fuss - the giblets will have to be changed. But leaks to such products are unknown.

We decided to bypass the air-foam fire extinguishers. Today, they are practically not in demand, because they do not tolerate negative temperatures and are not trained to work with electricity. Water - it is water …

If you want the fire to go out on its own, then …

… you have to purchase an automatic assistant (photo 5). Unfortunately, you can’t put it on a car, but in a garage or warehouse it is easy.

Let’s figure it out first with the “disk” (or with the “flower” - to which it reminds someone). Such a module is able to extinguish and localize fires of solid and liquid materials, and also fights burning electrical equipment with voltages up to 5000 V. It is too tough for him only those substances that burn without access to air - magnesium, sodium, etc.

Using a “drive” is simple - just hang it over a “dangerous” place. In case of fire, the petals of the product instantly open and the extinguishing powder falls into the combustion zone. If you wish, you can "turn it on" from the central console by applying a voltage pulse. Each such "flower" will be able to protect approximately 7 m2 of the surface, so for large areas will have to organize a kind of "flowerbed" on the ceiling.

The “tube” is arranged somewhat differently. It is made of glass and in a fire just collapses. If desired, the fire extinguishing process can be accelerated - smashed from one of the ends. To protect a large room with one "tube" also can not do.

Both the “disk” and the “tube” are disposable items: having fulfilled their duty, they “perish”.

If you want to be informed about the fire, then …

… take a look at photos 6 and 7. In front of us are fire detectors.

First, get acquainted with optoelectronic products. They constantly monitor the optical density of the environment, thus reacting to smoke. They are not trained to extinguish a fire, but they know how to squeak plaintively. The nature of the scream depends on the degree of danger - if things are really bad, then the squeak can give out an electrical signal. Food products - from batteries.

The heat detector is not autonomous and is itself completely helpless. The product should “report up” - that’s all.

If you don’t want anything at all, then …

… borrow a fire extinguisher from a neighbor for inspection. Inspectors can be fooled, but the fire is unlikely. However, if this, God forbid, happen, then they will probably help you - good people with fire extinguishers have not yet transferred. But you will not help anyone.

And the last one. Firefighters joke that any fire can be poured with a glass of water if done on time. So do not hide the fire extinguisher in the basement or in the bowels of the cluttered trunk …

1. Aerosol FL-500 arrived from Italy. The price is about 150 rubles.

2. OU-5 and OU-2. The producer - Open Society "Pozhtehnika", Torzhok. The numbers in the designation correspond to the capacity of the fire extinguisher and can range from 2 to 80 liters. In the latter case, two 40-liter cylinders mounted on a common trolley are used. The mass of products - from 6.5 to 239 kg, prices - from about 380 to 6100 rubles.

3. OP-5 (3) and OP-1 (3). The producer - Open Society "Pozhtehnika", Torzhok. There are seven brothers in the family - the smallest OP-1 (Z) has a mass of only 2 with a small kilogram, but the OP-100 (Z) pulls two centners. Prices, of course, are also different - from about 200 to 4800 rubles.

4. OP-5 (G) and OP-2 (3). Manufacturer - Machine-building plant "Stamp" them. B. Vannikova, Tula. Cases of such fire extinguishers can have a volume of 2 to 10 liters, their cost is about 315 to 550 rubles.

5. A nice disk is called the MPP (powder fire extinguishing module) “Buran”, and the “tube” is dubbed the OSB (self-propelled powder fire extinguisher). The manufacturer is Epotos, Moscow. The “tube” will cost you approximately 335 rubles, the “disk” will pull about 735 rubles.

6. Detectors fire autonomous smoke optoelectronic IP 212–43M and IP 212–40. The manufacturer is the company "IVS-Signalspetsavtomatika", Obninsk. The price is about 1200 rubles.

7. The announcer fire thermal IP-109. For some reason, the manufacturer in the passport is not indicated. The cost of the product is only 16 rubles.
