What type of fire extinguisher is specifically designed for oil and flammable liquids?

The correct choice is designed for controlling fires involving flammable liquids, such as oils, gasoline, and solvents. These types of fires can be very challenging because they typically involve liquids that can spread quickly and ignite unintentionally. Class B extinguishers are filled with non-conductive agents that effectively smother the flames and cut off the supply of oxygen, making them ideal for handling fires from flammable liquids.

In contrast, Class A extinguishers are meant for ordinary combustibles like wood, paper, and textiles, which require a different approach to extinguishing fires. Class C extinguishers are specifically for electrical fires, using non-conductive agents suitable for use near live electrical equipment. Finally, Class D extinguishers are tailored for combustible metals, such as magnesium and sodium, which require specialized agents as they behave differently than typical flammable liquids and solids. Each class of extinguisher addresses specific fire types, underlining the importance of selecting the right one for effective fire control.
