What does a Class A fire involve?

• A. Paper and wood fire
• B. Cooking oil fire
• C. Petrol fire
• D. Electrical equipment fire

Answer: (A)

Fires are categorized to guide the safest and most effective extinguishing approach. A Class A fire involves ordinary combustibles such as paper, wood, cardboard, and textiles. These materials burn mainly because of heat that raises the fuel to its ignition point, so cooling with water-based extinguishers or foam is typically effective. The other options describe fires fueled by different substances: cooking oil is treated separately (often Class F), petrol is a flammable liquid (Class B), and electrical equipment fires involve electricity (Class C). So the paper and wood fire is the one that fits ordinary combustibles.
