On what type of fire is a Class B fire extinguisher used?

A Class B fire extinguisher is specifically designed for fires that involve flammable liquids, such as oils, gasoline, grease, and other similar substances. These types of fires typically occur in kitchens, garages, and industrial settings where such materials are present. The firefighting agents used in Class B extinguishers, like foam, dry chemical, and carbon dioxide, are effective at smothering flames and preventing the fire from spreading.

Understanding the types of fires associated with different classes of extinguishers is crucial for effective fire safety and response. Class A extinguishers are intended for common combustibles like wood and paper, while Class C extinguishers target electrical fires. Composite fires encompass multiple types of materials, which may require a different approach, typically using extinguishers rated for the specific classes involved. Hence, identifying the appropriate extinguisher for the type of fire is vital for ensuring safety and compliance with fire safety regulations.
