What do the AFFF proportioning pumps service?

Explanation:
AFFF proportioning pumps are designed to deliver foam concentrate to every fixed foam station that could face a fuel or flammable-liquid fire, so they must service all spaces where such fires are likely. On a ship, that includes the hangar bays where aircraft and fuels are handled, and the weapons elevators that move ordnance into position, since these areas are high-risk for fuel fires. They also service RARs and MMRs, which are ordnance-related spaces that require foam protection. In addition, the system extends to JP-5 pump rooms (fuel supply areas), EDGs (engine-driven generators with potential fuel sources), the incinerator (a location with waste combustion and possible flare-ups), and hose reels used for rapid, portable foam application. Because the proportioning pumps support all of these spaces, the option listing every one of them best captures the full scope of what the AFFF system covers.
