Which class of fire involves flammable liquids?

Class B fires involve flammable liquids, which can include substances like gasoline, oils, grease, and solvents. These materials have a low flash point, making them particularly hazardous and capable of igniting easily. Fighting Class B fires typically requires agents that can suffocate the flames or inhibit the chemical reaction, such as foam, dry chemical, or carbon dioxide extinguishers. Understanding the classification of fires is crucial for effective fire prevention and firefighting strategies, as using the wrong type of extinguisher can exacerbate the situation.
