A class B fire extinguisher is designed to put out which type of fires?

A class B fire extinguisher is specifically designed to combat fires fueled by flammable liquids, which includes materials like gasoline, oil, grease, and other similar substances. These extinguishers use agents that can effectively suppress and control fires by creating a barrier between the fuel and the oxygen in the environment.

In contrast, electrical fires typically require a class C extinguisher, which is formulated to handle fires involving energized electrical equipment. Wood and paper fires are classified under class A fires, which are extinguished using different methods and agents suitable for solid combustible materials. Cooking oil fires often require class K extinguishers, which are specifically designed for kitchen fires involving oils and fats. Class B extinguishers thus serve a crucial role in fire safety, especially in environments where flammable liquids are present.
