For every person, the word “fire” is terrifying. Fire is a completely uncontrollable phenomenon that destroys everything in its path. Therefore, people need to know about him as much as possible in order not only to resist him, but also to be able to warn him. So, let's see what the classification of fires is all about.
There are several types of classifications:
1. Fires are divided by rank. It should be said that such a separation is simply necessary. This is necessary in order to correctly calculate the right number of equipment and people at the crucial moment. There are basically six types of fires:
• If a smoke signal arrives, two vehicles leave for the place of call. In the event that a fire is confirmed, firefighters proceed directly to extinguish. This is type 1.
• If the fire intensifies, two more additional vehicles are called to the scene of the tragedy. And now at the scene 4 departments work. This type - 1BIS
• Two more additional cars leave if the fire area increases and there is no water source nearby. So, if there are 6 branches on a call, this is rank No. 2.
• If the situation escalates even more and 10 departments are involved in the extinguishing, this is already rank No. 3.
• When type 4 is called, 13 departments work at the fire site.
• If the situation is tense to the limit, and 15 departments work on a call - this is rank No. 5.
2. There is also a classification of fires by type of place of ignition:
• If a fire has occurred in a manufacturing site, warehouse or factory, this is an industrial type.
• If a fire happened in the apartment - household.
• And, of course, if forests, steppes and swamps burn, this is a natural type.
3. There is a classification of fires by building density at the site of ignition:
• If a separate building is on fire and the building density does not exceed safe (20%), this is the so-called separate type of fire.
• If the fire covers the territory built up by 20% or 30% - this is a solid type.
• If the building density is more than 30%, the fire has a colorful name - “terrible fire storm”.
• And the last type is smoldering.
4. Another classification of fires, depending on which substances burn:
Class "A" - solids:
• coal burns or smolders, textiles - A1;
• plastic burns, but does not smolder - A2.
Class "B" - liquid substances:
• gasoline, ether and oil products burn, that is, those substances that do not dissolve in water - B1;
• alcohol or glycerin burns, that is, substances soluble in water.
Class "C" - ignition of gas, for example, propane.
Class "D" - metals burn:
• light metals - D1;
• alkaline - D2;
• compounds that contain metal - D3.
Class “E” - electrical installations are damaged by fire.
Class “F” - radioactive waste is burning.
5. Another classification reflects the types of fires depending on the depth of ignition:
• Fire in vehicles.
• Ignition of fields or steppes.
• Fire in depth, in a mine or mine.
• Buildings are on.
The causes of fires are diverse. The main one is careless handling of fire. Also the most common reasons include non-compliance with fire safety, self-ignition of substances, lightning, arson, improper use of household appliances, etc.
Fire fighting consists of two parts: prevention and immediate action during a fire. The main methods of prevention: periodic check of electrical wiring (sockets, adapters, etc.), timely replacement of old household appliances, careful handling of electricity, etc. In order to defeat the fire, you must first eliminate the source of ignition, and then extinguish the remaining flame. The most affordable extinguishing media should always be nearby. These include sand and a fire extinguisher. Water, various tarpaulins or clothes are also used.
Remember, very often a fire takes the lives of innocent people, be careful with fire!
