Which class of fire involves flammable liquids?

The classification of fires is based on the type of fuel that is burning, and flammable liquids fall into a specific category. Class B fires are specifically associated with combustible and flammable liquids, such as gasoline, oil, and alcohol. These materials are known for their ability to ignite and sustain a fire, often producing dangerous and volatile situations.

Understanding that Class B fires involve hydrocarbons and other liquids is crucial for proper fire suppression strategies. Fire extinguishers and firefighting techniques used for Class B fires typically involve suppressants that can disrupt the chemical reactions occurring during combustion, such as foam, dry chemical agents, or CO2. This knowledge is vital for firefighters to effectively control and extinguish such fires, ensuring safety for both individuals and the environment.

In contrast, Class A involves ordinary combustibles like wood or paper, Class C pertains to energized electrical equipment, and Class D relates to combustible metals, each requiring different approaches for effective firefighting.
