A variety of fire extinguishers exist to chosen from. Choosing the correct one for a home can seem overwhelming. Each home should have at least one fire extinguisher but, having the correct one is also very important. Experts in fire protection advise having one for the workshop, garage and kitchen. Dry chemical extinguishers have a benefit over c02 extinguishers because they use a non flammable material that decreases the chance of the fire reigniting.

Fire extinguishers are separated into four different categories, according to the type of fire. These extinguishers come with a number rating to show how much fire the extinguisher can handle. Higher numbers mean that the extinguisher has more fire fighting power. Below is a list of the categories that will serve as a quick reference guide for choosing the appropriate type of extinguisher.

Cardboard, paper, types of plastic and wood require a class A extinguisher. Look at the number rating to know the amount of fire it can put out and how much water is in the extinguisher.

Kerosene, gasoline, oil and grease need a class B extinguisher. To know how much square footage can be controlled with this extinguisher, pay attention to the rating on the canister.

Class C extinguishers are used for electrical fires like outlets, circuit breakers, wiring or appliances. DO NOT use water for these types of fire because of the risk of being shocked. These extinguishers do not come with a number rating. The extinguishing agent is non conductive.

Chemical labs use class D extinguishers. This extinguisher is for certain metals like magnesium, sodium, potassium and titanium. They are not used for multiple purposes and do not have a number rating.

Multiple rating fire extinguishers are recommended due to the fact that some fires involve a combination of materials. Choose one that is rated for several uses such as ABC.

Fire extinguishers most commonly used are:

APW, also known as water extinguishers, are under pressure from water and used for class A fires. Do Not use water on electrical or grease fires. Doing so will make the fire spread. Use these extinguishers for putting out fires that contain common flammable items.

Dry element extinguishers are obtainable in several arrays. These extinguishers, suited for class A, B and C fires, are under pressure from nitrogen that is a powder or foam.

Extinguishers with sodium and potassium bicarbonate are classified as BC extinguishers. They are a dry element extinguisher that leaves a corrosive residue behind. This means that the clean up must be done immediately to stop any items from being damaged.

ABC extinguishers are a multiple purpose fire extinguisher. This type contains monoammonium phosphate which is a yellow powder that leaves a sticky residue. It can damage appliances like computers.

CO2, also known as carbon dioxide, extinguishers are meant for class B and C fires. A non flammable gas known as carbon dioxide is used. It is not uncommon to see dry ice come out of the nozzle because of the amount of pressure. These are not suggested for A fires. It is possible that enough oxygen may not be displaced to put the fire out, which can result in the fire reigniting.

The residue left behind by c02 extinguishers is not damaging which gives them an advantage over other extinguishers. They are good for putting out electrical fires.

A dangerous situation can occur if the wrong type is used.

These are merely a list of common forms of fire extinguishers. A variety of others are available as well. Use the classification and your needs to select the right one for you.
