What type of fire is classified as Class B?

Class B fires are specifically defined as those involving flammable liquids and gases. This classification includes substances such as gasoline, oil, jet fuel, and certain solvents, all of which are capable of igniting and producing significant fires. The unique challenge of Class B fires is that they often require specific extinguishing agents to address them effectively, such as foam or dry chemical agents, instead of water, which can spread the fire.

In the context of fire safety and firefighting, recognizing the correct class of fire is crucial for deploying the right strategies and tools. The other classifications mentioned do not directly correspond to Class B fires: electrical fires fall under Class C, combustible materials producing ash are classified as Class A, and combustible metals are designated as Class D. Each class has its own distinct characteristics, and understanding these distinctions is vital for effective response and safety measures in aviation and other fields.
