What is the target for a Class B fire extinguisher?

A Class B fire extinguisher is specifically designed to combat fires that involve flammable liquids and gases. This includes materials such as gasoline, oil, paints, and solvents. The extinguishing agents used in Class B extinguishers, such as foam, carbon dioxide, or dry chemical agents, are effective in smothering and interrupting the chemical reaction that fuels these types of fires, preventing them from spreading and controlling the blaze.

In contrast, Class A fire extinguishers are aimed at ordinary combustibles like wood and textiles, while Class K extinguishers are specialized for cooking oils and fats. A Class C extinguisher addresses fires involving energized electrical equipment. Each class of fire and corresponding extinguisher is tailored for specific materials, which is crucial for safe and effective firefighting.
