What is Class A?

Explanation:
Fire classification by fuel type is used so crews know how a fire will behave and what extinguishing method to use. Class A refers to solid combustibles—materials that burn as solids and often leave ash, such as wood, paper, and textiles. Because the fuel is a solid, these fires are cooled to stop the reaction, so water (for cooling) is effective; this is why “Flammable Solids” best describes Class A. Liquids, gases, and metals belong to other classes and behave differently, which is why they’re not described as Class A.
