Which type of combustibles are addressed by a "B" class fire extinguisher?

• A. Wood, cloth, paper
• B. Flammable liquids such as paint and gasoline
• C. Energized electrical equipment
• D. Combustible metals

Answer: (B)

A "B" class fire extinguisher is specifically designed to combat fires involving flammable liquids and gases. This includes substances like gasoline, paint, oil, and other similar materials that can ignite and create hazardous fire conditions. Flammable liquids are capable of spreading quickly and generating intense flames, making it crucial to use the correct type of extinguisher that can effectively suppress these specific types of fires.

Utilizing a "B" class extinguisher ensures that the fire can be doused without the risk of making the situation worse, as some other types of extinguishers may not be effective on flammable liquids. For instance, using water on a flammable liquid fire can cause the fire to spread due to the liquid's tendency to float on water. Hence, the proper identification of the class of fire extinguishers is vital for safe and effective emergency response actions.
