KNOCKDOWN foam concentrate works in two ways. First, KNOCKDOWN improves the
penetrating capability of water. It reduces the surface tension of plain water
which allows it to penetrate surfaces where water might normally run off, to
reach deep-seated fires. This helps reduce the amount of water required to
extinguish the fire and also provides quicker knockdown. Secondly, KNOCKDOWN
increases the heat absorbing capabilities of water. Foaming ingredients give
water the ability to adhere to vertical surfaces which allows the water longer
contact with the fuel. The longer the water is in contact with the fuel, the
more heat it is able to absorb. A coating of Class A foam may also be used for
exposure protection to prevent fuels from igniting by raising their moisture
content and providing a tough protective barrier to an oncoming flame front.
