Which extinguisher class is represented by a Green Triangle?

• A. Class B
• B. Class A
• C. Class C
• D. Class K

Answer: (B)

The marking on an extinguisher label uses shapes and colors to identify which type of fire it’s meant for. A green triangle specifically signals fires involving ordinary combustibles—things like wood, paper, and fabric. That’s Class A. Extinguishers with this symbol are designed to remove heat, often with water or water-based agents, making them effective for cooling the fuel so the fire can’t continue. Other fire types use different symbols and colors, so the label helps you pick the right extinguisher quickly and avoids using the wrong one on electrical fires, fuels, or kitchen fats/oils. Always check the extinguisher’s label to confirm it matches the fire you’re confronting.
