What is the traditional symbol for a Class A fire extinguisher?

• A. Green Triangle
• B. Blue Circle
• C. Red Square
• D. Yellow Star

Answer: (A)

The symbol for a Class A extinguisher is a green triangle. This class covers ordinary combustibles like wood, paper, and cloth. The green color and triangle shape are used in many training materials to quickly signal that the extinguisher is suitable for these common materials, making it easy to recognize in an emergency. The other shapes and colors represent other fire classes in the traditional coding: a red square is associated with flammable liquids, a blue circle with electrical fires, and a yellow star with metal fires. While labeling systems vary in real equipment, this green triangle tradition is a common teaching cue for Class A.
