A Class B fire extinguisher is primarily used for which type of fire?

A Class B fire extinguisher is specifically designed to combat fires that involve flammable liquids, such as grease, oil, and other petroleum-based products. The effectiveness of a Class B extinguisher comes from its ability to smother the flames and prevent the fire from spreading. This is crucial in environments such as kitchens or industrial settings where these materials are often present.

While other classes of extinguishers target different types of fires—Class D for combustible metals and Class C for electrical fires—a Class B extinguisher is essential for situations involving flammable liquids and gases. Understanding the classification of fire extinguishers is key for effective fire safety management, ensuring that the right type of extinguisher is used in an emergency to help prevent further damage and ensure safety.
