Class B Fire Extinguishers Are Best Suited To Fight What Kind Of Fires? (Question)

Class B fires involve flammable and combustible liquids such as gasoline, alcohol, oil-based paints, lacquers. Therefore, extinguishers with a B rating are designed to extinguish fires involving flammable and combustible liquids.

Which types of fire extinguishers used for Class B fire?

CO2: A carbon dioxide fire extinguisher works on a Class B fire by expelling CO2 to suffocate the fire, removing the oxygen necessary to keep it burning. It also helps with removing the heat, as the discharge is very cold.

Which type of fire extinguisher is best suited for Class A Class B and Class C fires?

Dry chemical fire extinguishers extinguish the fire primarily by interrupting the chemical reaction of the fire triangle. The most widely used type of fire extinguisher is the multipurpose dry chemical that is effective on Class A, B, and C fires.

What is the best agent to extinguish a Class B fire?

In many cases, water will only spread the fuel around and create more fire. To extinguish a Class B fire, you want to cut off the oxygen. You can use carbon dioxide gas to dilute the oxygen available and stop the burning. Smothering the fire with bicarbonate (baking soda) or potassium carbonate will also work.

What are Class B and C fires?

Class B fires which involve flammable liquids and gases, solvents, oils, greases (excluding cooking oils/greases in depth) tars, oil-based paints and lacquers. Class C fires which involve energized electrical equipment.

What is a Class A fire extinguisher?
