AFFF mixing stations are located through which level of the ship?

• A. O2 level
• B. O4 level
• C. Deck level
• D. O3 level

Answer: (D)

AFFF mixing stations are placed on the O3 level to line up with the ship’s fire-main distribution and give crews quick, direct access to both the foam concentrate and the water supply. This level is chosen because it sits in a protected, central area where foam proportioners can inject concentrate into the water supply close to where foam will be used, making deployment fast and reliable. Putting stations on the deck would expose them to weather and damage, and levels like O2 or O4 aren’t configured to support the foam system’s piping and maintenance access, so O3 is the practical, standard location.
