What type of extinguisher is commonly used in residential settings?

The Class ABC extinguisher is commonly used in residential settings because it is designed to handle multiple types of fires, making it versatile for home environments. It is capable of extinguishing fires that involve ordinary combustibles such as wood and paper (Class A), flammable liquids like gasoline and oil (Class B), and energized electrical equipment (Class C).

This versatility is particularly important for residential areas where a variety of fire hazards exist, including kitchen fires, electrical fires, and fires involving everyday materials. Having a Class ABC extinguisher allows homeowners to be prepared for different types of fire emergencies that might occur in their homes. In contrast, Class K extinguishers are specifically designed for cooking oils and fats, which are not a concern in every home, and Class D extinguishers are intended for metal fires, generally found in industrial or specialized settings rather than residential environments. Thus, the Class ABC extinguisher is the most practical choice for enhancing fire safety in a residential context.
