What type of fire is classified as a Class B fire?

A Class B fire is specifically characterized by the presence of flammable liquids, gases, and greases. This classification is crucial for understanding how to effectively respond to such fires, as the materials involved can lead to rapid spreading and intense flames if not handled properly. Firefighters must utilize the appropriate extinguishing agents—such as foam, dry chemical, or CO2—designed to suffocate the flames and prevent re-ignition.

In contrast, fires involving electrical equipment fall under Class C, while ordinary combustibles like wood and paper are categorized as Class A fires. Reactive metals, such as sodium or potassium, are classified as Class D fires, which require special extinguishing methods. Understanding these classifications helps ensure that firefighters apply the correct techniques and equipment when responding to different types of fire emergencies.
