What material is typically involved in Class B fires?

Class B fires are specifically associated with flammable liquids and gases. These materials include a wide range of substances such as gasoline, oil, grease, and solvents that can ignite and spread rapidly, posing significant dangers in various environments where they are stored or used. Firefighting techniques and extinguishing agents for Class B fires are tailored to effectively combat the unique hazards these materials present.

In contrast, the other options highlight different classes of materials that correspond to other fire classifications. For example, combustible cooking oils are typically classified under Class K fires, which focus on kitchen-related fires. Electrical wires would be involved in Class C fires that include electrical equipment, while wood and paper are categorized under Class A fires. Understanding these classifications helps firefighters select the appropriate firefighting strategies and extinguishing agents for different types of fires.
