What class fires are CO2 extinguishers suitable for?

CO2 extinguishers are specifically designed to handle Class B and Class C fires, making them versatile tools in fire emergencies. Class B fires involve flammable liquids, such as gasoline or oil, and CO2 is effective in displacing oxygen, thereby smothering the flames. Class C fires are electrical fires, and since CO2 is non-conductive, it can safely extinguish these types of fires without risk of electrical shock.

While Class A fires involve ordinary combustibles like wood or paper, CO2 extinguishers are not the most effective choice for these, as they primarily require cooling. Therefore, identifying the suitable classes for CO2 extinguishers highlights their capabilities in tackling both flammable liquid and electrical hazards.
