Which symbol identifies Class A extinguishers (color and shape)?

• A. Green triangle A
• B. Red square B
• C. Blue circle C
• D. Yellow star D

Answer: (A)

Understanding the symbol system used on fire extinguishers: a color paired with a simple shape is used to show which class of fire the extinguisher is suitable for. For Class A fires, which involve ordinary combustibles like wood, paper, or cloth, the identifying symbol is a green triangle. This green triangle is the quick, at-a-glance cue that tells responders this extinguisher is intended for those kinds of fires, and it helps prevent using the wrong type during an emergency. Other classes use different color-shape combinations: a red square is used for Class B fires (flammable liquids), a blue circle for Class C fires (energized electrical equipment), and a yellow star for Class D fires (combustible metals). These distinct symbols keep the applicable uses separate, reinforcing safety by guiding proper extinguisher selection.
