Fire extinguishers are grouped into several classes where they are being used for. These extinguishers also have a numerical rating for their use. Class A extinguishers are being used for ordinary aliment materials. These include document, cardboard, plastics, and solid wood. The numerical rating found on this kind of extinguisher shows the amount of water it can hold and the amount of fire it can extinguish. here Class W fire extinguishers are specially formulated to put out fires which care triggered by flammable and aliment liquids like oil, gasoline, grease, and kerosene. Typically the numerical rating for Course B extinguisher indicates the area of fire in square feet it can extinguish.

Class C fire extinguishers put out fires which involve electrical equipment, including appliances, outlets, wirings, and circuit breakers. Any time dealing with a class C fire, it is important to keep in mind that water should not be used to extinguish it because the chance of an electric surprise is great. Class Chemical extinguishers have extinguishing brokers that are non-conducive and they do not have a numerical rating. One of the most typical fire extinguisher types are those found in a chemical laboratory. This kind is categorized as Course D fire extinguisher and is for fires involving flammable materials like sodium, potassium, magnesium (mg), and titanium. Similar to Class C extinguishers, School D extinguishers do not have a numerical rating and are to be used exclusively for Course D fires.


Aside from these classifications, fire extinguishers are also categorized in line with the extinguishing agent used. Water extinguisher, also known as air-pressurized water extinguisher, is merely ideal for class A fires only. Using a normal water extinguisher on a Class Chemical or Class D fireplace will only associated with fire bigger so be careful when identifying the type of fire before utilizing a particular extinguisher. A water fire extinguisher is filled with water and is pressurized with o2, thus can be extremely dangerous in the wrong form of situation. Only fight a fireplace with a water extinguisher if you are sure that the fireplace is caused by ordinary combustible materials only.

Dry chemical extinguisher is another type of fire extinguisher and has a variety of types. This type of fire extinguisher is ideal for a combo of sophistication A, B, and C fires. Dry substance extinguishers can be filled with foam or powder, pressurized with nitrogen. Typically the regular type of dry chemical extinguisher is one which is filled with sodium bicarbonate and potassium bicarbonate. This is called the BC extinguisher. The BC variety leaves a mildly corrosive residue which must be cleaned immediately to prevent further damage.


Another variety is the ABC extinguisher which is a multipurpose dried out chemical extinguisher filled with monoammonium phosphate which is damaging to electrical devices. Compared to CO2 extinguishers, dry chemical extinguishers have the advantage because they leave a non-flammable remains on the extinguished materials.

On the other hand, CO2 extinguishers possess the advantage over dry chemical extinguisher such that they don’t leave a harmful residue on an electronic device. These extinguishers contain carbon dioxide and are highly pressurized to extinguish a fire.
