These CAFS appliances can also be used for large urban fire incidents in the ACT.

Being the first of its kind in Oz to use the CAFS technology I've seen how these tankers worked during one bushfire incident a few years back in a Canberra suburb. some houses in one street were completely blanketed in the foam. It looked as if it had snowed.
A huge advantage for the ACTRFS and Fire Brigade and also other fire services in Australia.

CAFS stands for compressed air foam system and there is a seperate foam concentrate tank in the system holding a concentrate that s like washing up liquid, this concentrate is mixed in with the water by a compressor and then fed down a dedicated cafs delivery line to the branch (again a special branch) the supposed advantages are very minimal amounts of both water and concentrate are used thereby reducing water damage, the hose is very light to handle - cos its full of bubbles thereby causing less effort on the part of the branchman especially if in BA, disadvantages are it makes a lot of mess, and allegedly in the UK the enviroment agency ain't too keen on it entering drains and watercourses - although the manufacturers seem to have ommitted that fact when selling it to brigades the foam can be made 'wetter or drier' by adjusting the settings at the pump, to get technical the foam acts as a 'surfactant' and clings to surfaces both cooling and smothering the fire - I think - from memory prior to retiring we had just got a CAFs pump in Humberside and this is where I have my info from, personally whilst in some situations its undobtably better in most I think crews will tend to use water alone as an extinguishing media.
