Which class of fire extinguisher is used for flammable liquids and gases?

Class B fire extinguishers are specifically designed to combat fires involving flammable liquids and gases, such as petroleum products, oils, paints, and solvents. These fires require a different approach than those involving solid combustibles. Class B extinguishers typically use a combination of dry chemicals, foam, or CO2 to effectively smother the flame and prevent re-ignition.

Flammable liquids and gases can produce significant and fast-spreading fires, highlighting the importance of using the appropriate extinguisher that can rapidly extinguish flames while minimizing hazards. The agents in Class B extinguishers help to break the combustion reaction, making them effective in controlling liquid fires that may spread quickly if not addressed promptly.

Understanding the classification system for fire extinguishers is crucial for both prevention and effective emergency response in situations involving different types of fuel sources.
