What is one common type of fire extinguisher used for flammable liquids?

The foam extinguisher is recognized as a common type of fire extinguisher used for dealing with flammable liquids. Its effectiveness stems from its ability to smother the fire and create a barrier between the fuel and the air, which is essential in preventing re-ignition. Foam extinguishers are particularly suited for flammable liquids like gasoline, oil, and solvents, making them a preferred choice in environments where such hazards are present.

Water extinguishers are not suitable for flammable liquids because water can spread the flames and worsen the situation. Dry powder extinguishers can be effective for flammable liquids, but foam extinguishers are specifically designed for this type of fire, making them more efficient in smothering burning liquids. Air-pressurized water extinguishers also primarily use water, which is again not suitable for flammable liquid fires, as it may exacerbate the fire rather than extinguish it.
