Class B fires involve what types of materials?

Class B fires primarily involve flammable and combustible liquids and gases. These materials include substances such as gasoline, oil, paints, solvents, and propane. When ignited, these substances can produce intense flames and are capable of spreading fire quickly. Effective firefighting strategies for Class B fires often involve the use of foam, dry chemical extinguishers, or carbon dioxide, as these methods can help to suppress the flames and prevent reignition.

The other categories, while they pertain to different types of fires, do not belong to Class B. For instance, wood and paper products are classified as Class A fires, which are common combustible materials. Electrical components represent Class C fires, which involve energized electrical equipment. Lastly, fires involving metals and alloys are designated as Class D fires. Understanding these classifications is crucial for firefighters as it aids in selecting the appropriate firefighting techniques and equipment for various fire scenarios.
