Several Types of Fire Extinguishers

Now that you’re aware of the four classifications of fires, the next step is to know what fire extinguisher will work best for a specific classification. There are uniquely designed fire extinguishers, and you need to choose the correct one to extinguish flames whenever you need to.

1. Foam Extinguishers

This type of fire extinguisher is commonly used for class A and B fires since it’s water-based. It extinguishes fires by generating a cooling effect on the fuel that’s causing the fire. After the foam is poured onto the burning liquid, it extinguishes by producing a barrier between the flame and fuel.

2. Dry Powder Extinguishers

You can choose dry powder extinguishers when you want to extinguish class A, B, and C fires altogether. Since it uses powder to douse the flames, it’s not recommended to use it in tight spaces as there’s a chance you can inhale the powder.

3. Water Extinguishers

For class A fires, it’s best to use water extinguishers. Buildings with a lot of organic materials such as coal, wood, or paper should have this fire extinguisher.

4. CO2 Extinguishers

For buildings that pose a high risk to electrical fires, CO2 extinguishers are essential to put them out efficiently. These can also douse Class B fires. It works by displacing the oxygen by which flame burns.

5. Wet Chemical Extinguishers

Restaurants should have wet chemical extinguishers since these areas have an abundance of cooking fats and oils.

If your building still doesn’t have these fire extinguishers installed, make sure you contact fire extinguisher installation services. There are many companies you can rely on to provide high-quality fire extinguishers.
