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

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

Answer: (C)

The main idea is that extinguisher classifications use simple color and shape codes on labels for quick identification. For Class C, which covers energized electrical fires, the traditional symbol is a blue circle. This blue circle is used to distinguish it from the other classes, which have their own shapes and colors: a green triangle for Class A (ordinary combustibles), a red square for Class B (flammable liquids), and a yellow star for Class D (metal fires). The blue circle uniquely signals electrical fires, guiding you to use extinguishing methods appropriate for energized equipment.
