Class C corresponds to which type of material?

• A. Flammable Solids
• B. Flammable Liquids
• C. Flammable Gases
• D. Combustible Metals

Answer: (C)

Classifying fires by the type of fuel helps decide how to respond. Class C is for flammable gases. Gases behave differently from solids or liquids because the fuel can mix with air and travel with air currents, sometimes spreading quickly and unpredictably. Because of this, the approach to handling a gas fire focuses on stopping the gas source and preventing accumulation, rather than smothering the flame with water or foam, which are more effective on solids or liquids. In practice, you’d emphasize isolating the gas supply and ventilating the area to avoid buildup, with extinguishing methods chosen to parade with the gas environment and the equipment involved. Recognizing this classification helps you understand why a gas fire needs different tactics than fires involving solids or liquids. Solids and metals belong to their own classes with distinct considerations, which is why the correct match for Class C is flammable gases.
