Which option below is most clearly a Class A fire example as used in safety training?

• A. A cooking oil fire
• B. A paper and wood fire
• C. An electrical panel fire
• D. Gas fire

Answer: (B)

Fires are grouped by the material that is burning. Class A covers ordinary combustibles—things like paper, wood, textiles—that burn and typically leave ash. They’re cooled effectively with water, which stops the heat and breaks the fire’s sustained reaction. The example showing paper and wood is the clear Class A instance because those materials are the quintessential ordinary combustibles described by this class. The other options involve fuels or conditions that belong to different classes: cooking oil is a cooking fat fire, not a typical Class A combustible; an electrical panel fire involves energized electrical equipment and is treated as a separate class; a gas fire involves flammable gas and is categorized differently as well.
