Which materials are typically involved in Class A fires?

• A. Gasoline
• B. Paper
• C. Electrical panels
• D. Aluminum

Answer: (B)

Fires that involve ordinary combustibles—things like paper, wood, cloth, and similar everyday materials—fall into Class A. Paper is a quintessential example of this group, so it best fits Class A. Gasoline is a flammable liquid, which is Class B. Electrical panels involve energized electrical equipment and are Class C (though classification can change if de-energized). Aluminum is a metal, and metal fires are Class D. So paper is the material that typically appears in Class A fires.
