If the Class A marking is colored, what color should it be?

• A. Green
• B. Red
• C. Blue
• D. Yellow

Answer: (A)

Color-coding is used on markings to quickly identify the fire class a device or material is associated with. When a colored marking is used for Class A, it is green. This aligns with the common scheme where Class A (ordinary combustibles like wood, paper) is represented by green, while other classes use different colors (for example, red for some classes, blue or yellow for others). The color helps inspectors and responders distinguish at a glance, reinforcing the letter designation A without needing to read it. So, the best answer is green.
