Which marking identifies Class B extinguisher?

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

Answer: (A)

Recognizing extinguisher markings helps you quickly identify which fires they can safely combat. Class B marks indicate flammable liquids, and the identifying symbol is a red square. This standardized combination makes it easy to grab the right extinguisher in an emergency. A green triangle marks Class A (ordinary combustibles), a blue circle marks Class C (electrical fires), and a yellow diamond marks Class D (flammable metals).
