From cooking accidents to faulty office wiring, there are many small issues that can result in a sudden fire and require the use of a fire extinguisher. Though they all perform the same task, extinguishers are classified into different categories based on their compounds and the types of flames they fight. Here are some of the types of fire extinguisher available on the market and how they work.

5 Common Types of Fire Extinguisher

1. Water

Water extinguishers use a stream of water to fight fires. They have a class A rating, which means they should only be used in fires involving paper, wood, textiles, plastics, and other commonplace combustibles. Since water conducts electricity, never use this type of extinguisher to fight an electrical fire.

2. Wet Chemical 

Wet chemical extinguishers have class K ratings, meaning they’re ideal for controlling grease, fat, and cooking oil fires. They stop a fire by combining with oils to create a soapy foam that cools down flames. This type of extinguisher is essential in any commercial kitchen.

3. Foam

Since foam prevents items from reigniting, foam extinguishers work on class A and B fires, which involve flammable solids and liquids such as gasoline and oil. Foam doesn’t conduct electricity, so this type of extinguisher is also safe to use on fires involving high-voltage appliances. 

4. Powder

Powder extinguishers have a C rating, useful for banishing fires caused by combustible metals that are electrically energized. Keep them in laboratories and power plants, in the event that metals such as plutonium, lithium, or uranium ignite.

5. Carbon Dioxide 

Carbon dioxide extinguishers have class B and C ratings, meaning they help control flammable liquids and electrical fires. The carbon dioxide removes the oxygen from a fire with a cold spray, so it doesn’t conduct electricity or leave residue in its wake.
