What colors are the AFFF solution valves?

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

Answer: (D)

The key idea is that AFFF solution valves are color-coded to let you identify the two control points at a glance, which is crucial during operations and emergencies. Red and green are used for these valves so you can quickly distinguish their functions and avoid cross-connecting lines. Typically, green signals the valve that should be opened to allow AFFF solution to flow, while red indicates the valve used to isolate or shut off the line. This red-green pairing helps you confirm the correct path for the foam solution and reduces the chance of opening the wrong valve in a high-stress situation. Always follow site labeling and procedures, but knowing that the AFFF valves are red and green will guide your actions and improve safety and efficiency.
