The green triangle symbol on an extinguisher identifies suitability for which class?

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

Answer: (A)

Pictograms on extinguishers show which types of fires they are designed to fight. A green triangle indicates suitability for ordinary combustibles—things like wood, paper, and textiles. That’s Class A. So the extinguisher with that symbol is intended for those fires. Other fire types, such as those involving flammable liquids, electrical equipment, or combustible metals, require different symbols and extinguishers.
