What is the correct classification for fires involving flammable liquids and gases?

Fires involving flammable liquids and gases are classified as Class B fires. This classification is specifically designated for materials such as oils, gasoline, paints, and other flammable liquids, as well as gases like propane and hydrogen. Class B fires require distinct firefighting methods, typically using foam, dry chemical agents, or carbon dioxide to effectively suppress the flames without exacerbating the situation.

Understanding the classification is crucial for firefighters, as using the wrong type of extinguishing agent can be ineffective or even dangerous. For instance, using water (commonly used for Class A fires involving ordinary combustibles like wood and paper) on a Class B fire could cause the flammable liquid to spread, making the fire worse. This nuanced understanding helps firefighters take the appropriate action quickly and safely in emergency situations.
