CO2 extinguishers are intended for which types of fires?

• A. Class A and B
• B. Class A and C
• C. Class B and C
• D. Class D and K

Answer: (C)

CO2 extinguishers are specifically designed for Class B and Class C fires. Class B fires involve flammable liquids, gases, and solvents, such as gasoline, oil, and paint. The CO2 extinguisher effectively displaces oxygen in the area of the fire, suffocating the flames and preventing them from spreading. Additionally, it is non-conductive, making it safe for use on Class C fires, which involve electrical equipment. The CO2 does not conduct electricity, allowing for safe application on live electrical fires without risk of shock or further fire hazards. Understanding the appropriate application of CO2 extinguishers is crucial in ensuring effective fire suppression. Other classes of fire, such as Class A (ordinary combustibles like wood or paper), Class D (combustible metals), and Class K (cooking oils and fats), require different types of extinguishing agents, making them unsuitable for CO2 extinguishers.
