What type of fire extinguisher is suitable for multiple purposes?

The choice indicating an ABC fire extinguisher is correct because it is designed to handle a wide variety of fire types. Specifically, an ABC extinguisher can effectively combat Class A fires (ordinary combustibles such as wood and paper), Class B fires (flammable liquids like gasoline or oil), and Class C fires (electrical equipment). This versatility makes it a highly suitable option for multiple purposes, especially in environments where various fire hazards may be present.

In contrast, other fire extinguisher classes are specialized for specific types of fires. For instance, a Class A extinguisher is ideal for ordinary combustibles but would be ineffective against flammable liquids or electrical fires. Similarly, Class B and Class C extinguishers are limited to their respective fire classes and do not provide the comprehensive coverage that an ABC extinguisher does. Therefore, the ABC fire extinguisher’s multi-purpose capability makes it the best choice in this scenario.
