What are Fire and Fire Extinguishers!
Let’s talk fire! And extinguishers.
You need three ingredients to make fire: fuel (like wood or gasoline), oxygen, and heat. Fire is a chemical reaction between oxygen and fuel. If you want to put out a fire, just get rid of one of those three things – fuel, oxygen, or heat. Removing the fuel is easy when the fire is controlled. For example, when you shut off the gas valve on a propane grill, the fuel stops flowing and the fire goes out.
Once the fire starts, it provides heat and keeps burning. That is why throwing water on a fire puts it out. When water hits fire it boils, turns to steam, and floats away, taking some heat with it. It also prevents oxygen from reaching the fuel. Most fire extinguishers work by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go out.
That’s exactly what happens when wood burns. The fire uses oxygen and expels carbon dioxide. So, carbon dioxide is sort of already burned – it won’t burn if you throw it on fire. Since carbon dioxide is a gas, it is easy to store and distribute. If squeezed into a steel canister, the gas streams out as you open the nozzle. Carbon dioxide is denser than oxygen. So when you spray the carbon dioxide on fire, it sinks under the oxygen, separating the fire from oxygen. No oxygen, no fire.

Carbon dioxide has several big advantages. Because the gas is squished into a canister, when it comes out it is super cold – at least minus 100 degrees Fahrenheit – removing heat from the fire. And when sprayed on a fire, carbon dioxide just floats away. That means no cleanup. When tossed on a fire, water will flow along the floor. This means water can spread the fire if the fuel is light enough to be carried.
So carbon dioxide removes two out of the three things you need to have a fire. And, unlike water, carbon dioxide doesn’t conduct electricity, so it is good for electrical fires. One hidden issue with using carbon dioxide is the weight, since the gas is compressed the pressure is tremendous. A 2KG CO2 fire extinguishers weighs about 7 to 8 KG, making it difficult to operate by some. Also CO2 fire extinguishers are best used in places consisting of sensitive electrical equipment (Server rooms, service rooms, etc.)
So is there a fire extinguisher that is more convenient and is capable of fighting most kinds of fire?
The answer: Yes!
Our ABC Fire extinguishers consist of fine mono ammonium phosphate, which is a fire fighting agent (also a fertilizer, talk about multitasking). Furthermore one can use dry powders for extinguishing large-scale fires, spillage fires, and three-dimensional fires. Mono Ammonium Phosphate is very popular as it is a user-friendly extinguishing medium for Class A, B, & C fires. .

Enquire from usWhat do you mean by class A, B, C and E types of fires?
A - WOOD - PAPER - CARDBOARD Fire Extinguishers with Class A rating are effective against Combustible Materials fires involving paper, cloth, or wood.
B - LIQUIDS - Fire extinguishers with a Class B rating are effective against Flammable liquids such as Cooking oil, gasoline, kerosene, or flammable paint.
C - FLAMMABLE GASES - Fire extinguishers with Class C rating are effective against Flammable Gasses such as Butane, Methane and others.
E - ELECTRICAL - Fire extinguishers with Class E rating are effective against electrical fires caused by live electrical equipment.

Therefore an ABC fire extinguisher can be used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thus separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire. Pressure is generated by gas cartridges stored inside the cylinder. Its force will last for 45 seconds and can reach 10 – 15 feet. These extinguishers will be found in a variety of locations. New buildings will have them located in public hallways. They may also be found in laboratories, mechanical rooms, break rooms, chemical storage areas, offices, university vehicles, etc.
