Comparing Fire Extinguisher Types

There are many types of fire extinguishers that can be used to tackle a fire. These include water, foam, CO2, powder, and wet chemical extinguishers, just to name a few. Each variation is designed for use on different types of fires.

Water extinguishers are the most common type of extinguisher and can be used on Class A fires involving combustible materials like wood, paper, and fabric.

Foam extinguishers are designed for use on Class B fires, which are fires that involve flammable liquids like gasoline and oil.

Powder extinguishers can be used on Class C fires, which are fires that involve electrical equipment. They can also be used on Class A and B fires.

Types & Uses Of Fire Extinguishers

1. Carbon dioxide extinguishers are the most effective type of extinguisher for Class B and C fires. They work by displacing the oxygen in the air, which smothers the fire. In many circumstances, CO2 fire extinguishers are the best option as in addition to smothering the fire, they do not leave any residue behind. 

2. Halogenated extinguishers are used mostly on Class B and C fires, which involve flammable liquids and electrical equipment. The extinguishing agent in a halogenated fire extinguisher is a Halon gas, which works by interrupting the chemical reaction of the fire.

3. Dry chemical extinguishers are the most common type of fire extinguisher. Like halogenated extinguishers, they work by interrupting the chemical reaction of a fire. This extinguisher type is effective on Class A, B, and C fires.

There are two types of dry chemical extinguishers, multipurpose and Class K. Multipurpose dry chemical extinguishers can be used on all three classes of fires. In contrast, Class K extinguishers are specifically designed for kitchen fires.

4. Wet chemical extinguishers are filled with a potassium acetate solution and are designed to smother fires in cooking oils and fats. They work by creating a barrier between the oxygen in the air and the fire’s fuel source.
