What type of fires do Class B extinguishers address?

Class B fire extinguishers are specifically designed to combat fires involving flammable liquids and gases. This classification includes substances such as gasoline, oil, grease, paint, solvents, and various gases that can ignite and contribute to a fire. The extinguishing agents in Class B extinguishers work by smothering the fire, removing oxygen, or inhibiting the chemical reaction fueling the fire, making them effective for the volatile nature of the materials involved.

Understanding this classification is crucial for ensuring proper fire safety measures and response strategies, especially in environments where flammable liquids and gases are present. Utilizing a Class B extinguisher on these types of fires is essential for effective and safe fire suppression; using inappropriate extinguishing agents on such fires could exacerbate the situation or lead to further hazards.
