Deciding on the best type of fire extinguisher can be a complicated task due to many fireplace extinguisher types available. An individual should be very conscious when you choose a fire extinguisher because each kind is intended to put out a fireplace caused by different materials.

Fire extinguishers are categorized into several classes where they are being used for. These kinds of extinguishers also have a numerical rating for their use. Class A extinguishers are being used for ordinary aliment materials. These include papers, cardboard, plastics, and wood. 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 away fires which care triggered by flammable and combustible liquids like oil, gas, grease, and kerosene. Typically the numerical rating for Class B extinguisher indicates the area of fire in square feet it can extinguish.

Class C open fire extinguishers here put out fires which involve electrical equipment, including appliances, outlets, wirings, and circuit breakers. Whenever dealing with a school C fire, it is important to understand that water should not be used to extinguish it because the risk of an electric jolt is great. Class D extinguishers have extinguishing brokers that are non-conducive and they do not have a numerical rating. One 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, and titanium. Similar to Class C extinguishers, Class D extinguishers do not have a numerical score and are to be used exclusively for School D fires.

Aside from these classifications, fire extinguishers are also categorized in line with the extinguishing agent used. Normal water extinguisher, also known as air-pressurized water extinguisher, is merely suited to class A fire only. Using a normal water extinguisher over a Class D or Class D fireplace will only make fire bigger so be careful when identifying the sort of fire before by using a particular extinguisher. A new 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 fire 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 fireplace 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 chemical substance extinguishers can be packed with foam or powder, pressurized with nitrogen. Typically the regular type of dried out chemical extinguisher is one which is filled with salt bicarbonate and potassium bicarbonate. This is called the BC extinguisher. The BC variety leaves a mildly rust residue which must be cleaned immediately to stop further damage.

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

On the other hands, CO2 extinguishers have the advantage over dry chemical extinguisher such that they don't leave a harmful remains on an electronic device. These kinds of extinguishers contain carbon dioxide and are highly pressurised to extinguish a open fire.
