What is the classification of fires that consists of flammable liquids including gasoline and diesel?

The classification of fires that includes flammable liquids such as gasoline and diesel is recognized as Class B. These fires involve combustible liquids and gases, which can ignite and spread rapidly, posing significant hazards. Class B fires require specific extinguishing agents, like foam, powder, or CO2, designed to tackle fuel-based fires effectively. Using the appropriate extinguisher is crucial because other types of extinguishing methods, like water, may not effectively suppress this type of fire and can even exacerbate the situation by spreading the flames.

In contrast, Class A fires involve ordinary combustibles such as wood, paper, and fabric; Class C fires pertain to electrical equipment; and Class D fires deal with combustible metals, each requiring different strategies and extinguishing agents tailored for their unique characteristics. Understanding these classifications helps in selecting the correct firefighting approach and equipment during emergencies.
