Which fire classification is for ordinary materials such as wood and paper?

The classification that pertains to ordinary combustible materials like wood, paper, and fabric is known as Class A. This class is specifically designed for fires that involve materials that ignite and burn easily, which are common in many environments such as homes and construction sites. When extinguishing Class A fires, water and certain types of extinguishing agents that can absorb heat and cool the burning materials are effective. Understanding this classification is crucial for safety protocols, ensuring that appropriate fire-fighting methods and equipment are readily available to handle such incidents safely.
