What type of materials do Class A fires primarily involve?

1. Flammable liquids

2. Combustible metals

3. Papers and textiles

4. Electrical equipment

The correct answer is: Papers and textiles

Class A fires primarily involve ordinary combustible materials that are typically found in homes and buildings. These materials include items such as paper, wood, cloth, rubber, and some plastics. The characteristics of Class A fires are significant because they can be extinguished using water or foam, which works to cool the burning materials and interrupt the fire's combustion process. Papers and textiles are common examples of materials that ignite easily and can sustain a burning reaction, making them central to understanding Class A fires. Recognizing the types of items classified under Class A fires is crucial for effective firefighting strategies and for ensuring the safety of individuals responding to such incidents.
