Which fire extinguisher type is most commonly used in homes?

The ABC fire extinguisher is the most commonly used type in homes because it is an all-purpose extinguisher effective against a variety of fire classes. Specifically, it can tackle Class A fires, which involve ordinary combustibles such as wood, paper, or cloth; Class B fires, which involve flammable liquids like gasoline or grease; and Class C fires, which are electrical fires. This versatility makes the ABC fire extinguisher an ideal choice for residential use, as it can effectively manage the different types of fires that can occur in a household setting.

Other types of extinguishers, such as Class B, Class C, or Class D, are specialized and designed for specific types of fire risks. Class B extinguishers are suitable only for flammable liquids, Class C extinguishers are specifically for electrical fires, and Class D extinguishers are intended for combustible metals, which are not commonly found in residential environments. Therefore, the ABC fire extinguisher is favored for its comprehensive coverage and effectiveness in the typical home environment.
