Red/Green pipe markings indicate which system?

Red/Green pipe markings indicate which system?

• A. Fire Main
• B. Aqueous Film-Forming Foam (AFFF)
• C. Jet Propellant 5 (JP-5)
• D. Water

Answer: (B)

Piping color coding on Navy ships helps responders quickly identify what each pipe carries. A red/green striped marking specifically signals the Aqueous Film-Forming Foam (AFFF) fire-suppression system, which mixes foam concentrate with water to form a foam blanket that smothers hydrocarbon fires like JP-5 fuel fires. Seeing that red and green pattern tells you that the line is part of the foam firefighting system, not a plain water line or a fuel line. This makes AFFF the best choice for the system indicated by red/green markings.
