What type of fire extinguisher is suitable for flammable liquid fires?

A Class B fire extinguisher is specifically designed to put out fires that involve flammable liquids, such as gasoline, oil, grease, and other similar substances. These types of fires can occur in various settings, including garages, workshops, or even kitchens, where flammable liquids are present.

The effectiveness of Class B extinguishers comes from their contents, which typically include dry chemical agents or foam that smother the flames, cutting off the oxygen supply necessary for combustion. This smothering effect is particularly important for flammable liquid fires, which are often more difficult to control compared to solid material fires, due to the risk of spreading and the nature of the fuel involved.

In contrast, other classes of fire extinguishers serve different purposes. Class A extinguishers are suitable for ordinary combustibles like wood and paper, Class C extinguishers are intended for electrical fires, and Class D extinguishers are used for fires involving combustible metals. Understanding the correct type of fire extinguisher to use in various fire scenarios is crucial for ensuring safety and effective response to fire incidents.
