Which color circle background indicates a Class C extinguisher?

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

Answer: (A)

Fires involving energized electrical equipment are identified by a color-coded circular background on the extinguisher label. A blue circular background signals Class C, which is the category for electrical fires. Using a blue circle helps you quickly choose an extinguisher that uses a non-conductive agent suitable for live electrical equipment, like certain dry chemical powders or CO2. The other colored shapes indicate different classes: a green triangle corresponds to ordinary combustibles, a red square to flammable liquids, and a yellow diamond to metals. So the blue circle is the marker that points to Class C.
