Which fire extinguisher class is suitable for flammable liquids?

Type A
Type B
Type C
Type D

The correct answer is: Type B

Flammable liquids are categorized under Class B fire extinguishers. These extinguishers are specifically designed to combat fires involving liquids that can ignite, such as gasoline, oil, grease, and solvents. The extinguishing agents in Class B fire extinguishers, such as foam, dry chemical powders, or carbon dioxide, work effectively to suffocate the fire, preventing oxygen from reaching the flames and inhibiting combustion. Understanding the different classes of fire extinguishers is vital for effective fire safety management. Type A extinguishers, for example, are intended for ordinary combustibles like wood, paper, and cloth, while Type C extinguishers are designed for electrical fires. Type D extinguishers are suitable for fires involving combustible metals. Each type has specific applications, and using the correct extinguisher is crucial for safely extinguishing a fire without exacerbating the situation.
