What is a Class A fire?

A Class A fire involves ordinary combustibles, which are materials that can easily catch fire and include items such as wood, paper, cloth, rubber, and some plastics. Understanding this classification is crucial because it helps in selecting the appropriate firefighting methods and materials. For instance, water is typically effective in extinguishing Class A fires, as it cools and removes heat from the fire.

The other classifications focus on different types of materials. For example, fires involving flammable liquids are categorized differently due to their unique burning properties and the need for specialized extinguishing agents. Similarly, fires that involve electrical equipment require distinct handling methods to avoid electric shock or re-ignition, and fires involving metals have their own unique challenges, often needing agents that can handle high-temperature burns or specific chemical reactions. Recognizing these distinctions ensures that responders can act effectively and safely in various fire situations.
