How is AFFF concentrate piping maintained from the tank to the injection pumps?

• A. Maintained empty
• B. Maintained partially filled
• C. Maintained full
• D. Maintained pressurized

Answer: (C)

AFFF (Aqueous Film Forming Foam) concentrate piping is maintained full to ensure that the system is always ready to deliver the fire suppression foam efficiently in the event of a fire. A full system minimizes the possibility of air pockets and ensures that the concentrate is always available for injection when needed. Keeping the piping full also helps maintain a consistent concentration and pressure of the AFFF solution, which is crucial for effective fire suppression. This maintenance practice mitigates issues such as degradation of the AFFF concentrate, which can occur if it is left stagnant in partially filled or empty pipes, thereby ensuring operational readiness and system reliability.
