Which type of fire is classified as Class B?

Class B fires are specifically associated with flammable liquids and gases. This classification includes materials that can easily ignite and burn vigorously, such as gasoline, oil, alcohol, solvents, and various gases like propane and natural gas. The reason Class B fires are treated differently is that they require specific extinguishing agents that won't react adversely with the burning material. For instance, water is ineffective against Class B fires because it can spread the flammable liquid, while foam, dry chemical agents, and carbon dioxide are designed to smother the fire by cutting off the oxygen or cooling the fuel.

The other classifications involve different types of burning materials. Electrical equipment pertains to Class C fires, combustible metals to Class D, and Class A fires involve ordinary combustibles like paper and wood. Understanding these classifications is crucial for effective firefighting, as each type of fire presents unique hazards and requires tailored approaches for safe and efficient control.
