Compressed Air Foam System (CAFS) 3
Compressed Air Foam System (CAFS) 3 : A water / surfactant (foam) mixture, with compressed air forced into the mix. The result is a very homogeneous, small "air bubble" distribution; the resulting suppression agent is the consistency of soggy shaving cream, consisting of relatively pure surface area and little actual water. CAF is gaining favor in selected compartmental fire scenarios because of its high (explosive) conversion rate, on top of the penetrative advantages of the surfactant. It is also inappropriate for many fire scenarios because of that conversion rate, as an unmanaged steam expansion path will cook the firefighters. Secondary advantages are a graceful degradation during equipment failure; CAFs, without a compressed air supply, emit classic foam; without foam, water
