Which class of fire involves flammable liquids like gasoline and oil?

The classification of fires is based on the materials that fuel them. A Class B fire specifically involves flammable liquids, such as gasoline, oil, grease, and other petroleum products. These materials can ignite and create highly volatile fires, which require specific firefighting strategies and extinguishing agents to safely and effectively combat the flames.

Class B fires typically require the use of foam, dry chemical, or carbon dioxide extinguishers to smother the flames and interrupt the combustion process. Understanding this classification is crucial for fire safety and emergency preparedness, as it informs the selection of the appropriate extinguisher and firefighting techniques required to combat such fires effectively.

In contrast, Class A fires involve ordinary combustibles like wood, paper, and textiles; Class C fires are fueled by electrical equipment; and Class D fires involve combustible metals, which have entirely different characteristics and require specialized types of extinguishing agents.
