How many AFFF stations are there?

• A. 4
• B. 5
• C. 6
• D. 7

Answer: (C)

Foam fire suppression depends on distributing AFFF stations so you can reach a fuel fire quickly from multiple directions. Six stations are arranged to provide coverage in the flight deck, hangar bay, and the major fuel-handling and machinery spaces. This setup means there’s usually a station nearby to flood a space fast, which is crucial when dealing with aircraft fuel fires. Each station, when its valve is opened, releases foam that blankets the fuel, cools it, and separates it from air to suppress the flame and prevent reignition. Having six stations also adds redundancy, so a single station being out of service doesn’t leave a space unprotected. That’s why this count is the commonly used one.
