Selecting the most appropriate type of fire extinguisher can be a confusing task as a result of many fire extinguisher types available. You should be very aware if you choose a fire extinguisher because each kind is intended to put out a fire caused by different materials.

Fire extinguishers are classified into several classes to which they are being used for. These extinguishers also have a numerical rating for their use. Class A extinguishers are being used for ordinary combustible materials. These include paper, cardboard, plastics, and wooden. The numerical rating found on this type of extinguisher shows the amount of water it can hold and the amount of fire it can extinguish. Class B fire extinguishers are specially formulated to put out fires which care brought on by flammable and aliment liquids like oil, gasoline, grease, and kerosene. The particular numerical rating for Course B extinguisher indicates the area of fire in square feet it can extinguish.

Class C fireplace extinguishers put out fires which involve electrical equipment, including appliances, outlets, wirings, here and circuit breakers. Whenever dealing with a school C fire, it is important to keep in mind that normal water should not be used to extinguish it because the chance of an electric surprise is great. Class D extinguishers have extinguishing agents that are non-conducive and they do not have a numerical rating. A single of the most frequent fire extinguisher types are those found in a chemical laboratory. This type is categorized as Course D fire extinguisher and it 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 Class D fires.

Aside from these classifications, fire extinguishers are also categorized based on the extinguishing agent used. Normal water extinguisher, also known as air-pressurized water extinguisher, is merely well suited for class A fire only. Using a drinking water extinguisher over a Class D or Class D open fire will only make fireplace bigger so be aware when identifying the sort of fire before utilizing a particular extinguisher. The water fire extinguisher is filled with water and is pressurized with air, thus can be very dangerous in the wrong kind of situation.

Dry chemical extinguisher is another type of fire extinguisher and has a variety of types. This type of fire extinguisher is ideal for a blend of sophistication A, B, and C fires. Dry substance extinguishers can be packed with foam or powder, pressurized with nitrogen. The particular regular type of dried out chemical extinguisher is one which is filled with salt bicarbonate and potassium bicarbonate. This is the BC extinguisher. The BC variety leaves a mildly corrosive residue which must be cleaned immediately to stop 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 home appliances. Compared to CO2 extinguishers, dry chemical extinguishers have the advantage because they leave a non-flammable deposits on the extinguished materials.

On the other hands, CO2 extinguishers have the advantage over dry chemical extinguisher such that they may leave a harmful deposits on an electronic device. These extinguishers contain carbon dioxide and are highly pressurised to extinguish a fireplace.
