A green triangle containing a letter indicates an extinguisher which is to be used on

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

Answer: (A)

A green triangle with a letter is a pictogram that shows which fire class the extinguisher can be used on. The letter A identifies Class A, which covers ordinary combustibles such as wood, paper, and textiles. So this extinguisher is intended for those kinds of fires. It wouldn’t be the right tool for fuels (Class B), energized electrical equipment (Class C), or combustible metals (Class D), which use different symbols and letters.
