What type of fire is typically classified under Class B?

Class B fires are specifically classified as fires that involve flammable liquids and gases. This includes substances such as gasoline, oil, paint, and solvents, which can ignite and burn rapidly. The classification is essential for understanding the appropriate firefighting methods and extinguishing agents.

Using water on Class B fires can be dangerous, as it can spread the burning liquid further. Instead, foam, dry chemical agents, or carbon dioxide are recommended for suppressing these types of fires because they can effectively smother the flames. Recognizing the characteristics of Class B fires helps ensure safety and effective response in emergency situations.

The other classifications pertain to different materials, such as metals or ordinary combustibles, which are not applicable to Class B. This distinction is crucial for both fire safety training and effective firefighting strategies.
