Class Alpha fires are extinguished using which type of firefighting agent?

Class Alpha fires, which involve ordinary combustible materials like wood, paper, and cloth, are effectively extinguished using water. Water cools the burning material below its ignition temperature and helps remove heat from the fire. This cooling effect is crucial for stopping the combustion process of the fuel involved in Class A fires.

Water is particularly suitable for these types of fires because it can penetrate the materials, aiding in extinguishing and cooling the fire down. While other agents like dry chemical, foam, or carbon dioxide can be effective for different classes of fires, they do not address the specific characteristics of Class A fires as effectively as water does. Therefore, selecting water as the firefighting agent for Class A fires aligns with standard firefighting practices and principles.
