What type of fire extinguishers are best suited for fighting liquid fires?

Class "B" fire extinguishers are specifically designed to combat fires fueled by flammable liquids, such as gasoline, oils, and grease. These extinguishers often contain agents like foam, carbon dioxide, or dry chemical substances that effectively suppress flames caused by these types of materials. Using a Class "B" extinguisher helps to starve the fire of oxygen or cool the burning substance, which is crucial in preventing the fire from spreading.

In contrast, Class "A" extinguishers are meant for ordinary combustibles such as wood, paper, and cloth, making them unsuitable for liquid fires, where the risks of spreading flames are significantly higher. Class "C" extinguishers are designed for electrical fires and may not be effective against flammable liquids. Water-based fire extinguishers can exacerbate liquid fires, as water can spread flammable liquids, making Class "B" extinguishers the most appropriate choice for those situations.
