What is Class A fire primarily fueled by?

Class A fires are primarily fueled by ordinary combustibles such as wood, paper, cloth, rubber, and some types of plastics. This classification is essential in understanding the materials that can ignite and sustain fires in common environments, typically found in residential or commercial settings. Because these materials are readily available and often involve everyday items, Class A fires are among the most frequently encountered by firefighters.

Recognizing the correct classification helps fire service personnel determine the appropriate firefighting techniques and equipment. For instance, water is generally effective in combating Class A fires, as it cools the burning materials and extinguishes the flame. Understanding the nature of Class A fuels is crucial for effective fire prevention and safety measures in buildings and communities.
