The Different Types of Fire Extinguishers

Learn about various varieties of fire extinguishers, so you know which one to use for any given fire emergency.

There are many types of fire that can occur in your building. Each type of fire is caused by a different combustible object. Depending on what combustible started the fire, you’ll need a certain fire extinguisher for the job. Learn about various varieties of fire extinguishers, so you know which one to use for any given fire emergency.

Air Pressurized Water Fire Extinguishers

Air pressurized water fire extinguishers (APWs) are best for handling Class A fires, which are caused by paper, wood, plastic, trash, and cloth. These fire extinguishers have a mixture of water and pressurized air in them. Certain varieties use a detergent that forms foam when it’s used. APWs are necessary for any home or business. Compared to other fire extinguishers, they’re not as expensive, and they are deemed to be eco-friendly.

As a warning, do not use APWs on Class B, C, or D fires. This means they shouldn’t be used on fires caused by flammable liquids (Class B), electrical fires (Class C), or fires caused by combustible metals (Class D). Doing so can cause these fires to spread and become more dangerous.

Dry Chemical Fire Extinguishers

Dry chemical fire extinguishers put out fires by disrupting chemical reactions in a fire. They are safe to use on Class B and C fires and are among the most widely used extinguishers. While standard dry chemical extinguishers can only be used for Class B and C fires, there are multi-purpose variants that can also be used on Class A fires.

Wet Chemical Fire Extinguishers

These extinguishers are best used on Class K fires, which come from combustibles, including grease and cooking oils. This means they are often the best choice for fires that take place in the kitchen. They use potassium acetate as the dousing agent of choice, and they are vital to have in the event there is a disaster while cooking. For this reason, it’s best to have these fire extinguishers in restaurants or anywhere else that has a commercial kitchen.
