What type of extinguisher is used on fires caused by gasoline, oil, paints, burning liquids, and cooking fats?

The use of a Class B extinguisher is specifically intended for fires that involve flammable liquids such as gasoline, oil, paints, burning liquids, and cooking fats. These types of fires are particularly dangerous because they can spread quickly and are often challenging to extinguish with water, which can actually cause the fire to spread. Class B extinguishers typically contain agents like foam, carbon dioxide, or dry chemical powders that are effective in smothering the flames and cutting off the oxygen supply to the fire.

Understanding the classifications of fire extinguishers is crucial for effective fire safety and response. Each class is designed for different types of fires, meaning that using the incorrect type can not only be ineffective but can also exacerbate the situation. For instance, Class A extinguishers are meant for ordinary combustibles like wood and paper, while Class C extinguishers deal with electrical fires. Class D extinguishers, on the other hand, are suitable for combustible metals. Thus, knowing specifically that Class B extinguishers handle flammable liquids is vital for proper fire safety management.
