What type of fire extinguisher is suitable for a Class A fire?

A water extinguisher is effective for Class A fires, which involve ordinary combustibles such as wood, paper, and cloth. The water acts by cooling the burning material, effectively lowering the temperature below the ignition point and extinguishing the fire.

This method of extinguishment is particularly suitable for Class A fires because the primary goal is to remove heat from the fire to stop the combustion process. Additionally, since materials in Class A fires are often capable of holding heat, applying water helps not only to extinguish the flames but also to prevent re-ignition by thoroughly soaking the material involved.

Class A fires are distinct from other classes, such as Class B (flammable liquids) or Class C (electrical fires), where water would not be appropriate due to the risks of spreading the fire or causing electrical hazards. Understanding the classification of fires and the recommended extinguishing agents is crucial for safety and effective fire battle techniques.
