Which type of fire involves flammable liquids and gases?

Class B fires involve flammable liquids and gases. These types of fires occur when materials such as gasoline, oil, grease, and solvents ignite, as well as gases like propane and natural gas. The nature of Class B fires requires specific extinguishing agents, such as foam, dry chemical, or carbon dioxide, which are effective against burning flammable liquids and gases. Understanding this classification is crucial for firefighters, as it informs the appropriate methods and tools needed to extinguish these types of fires safely and effectively, preventing potential hazards and further damage.
