What does Class A fire represent?

• A. Fires involving flammable liquids
• B. Fires caused by electrical equipment
• C. Fires involving ordinary combustibles
• D. Fires involving combustible metals

Answer: (C)

Class A fires represent fires that involve ordinary combustibles, which are materials that can be found in most common environments. This category includes items such as wood, paper, cloth, rubber, and various types of plastic. These materials are characterized by their ability to ignite and sustain combustion when exposed to heat or flames. Understanding the nature of Class A fires is crucial for effective fire safety and prevention. It directly informs the type of fire extinguishers that should be used for successful suppression. For example, water-based extinguishers are typically effective against Class A fires. In contrast, the other categories address different materials: flammable liquids (Class B), electrical equipment (Class C), and combustible metals (Class D). Each of these requires specific handling and extinguishing techniques to mitigate the unique hazards they pose.
