Und ich verweise auf ein Statement eines Vertreters der britischen Feuerwehrgewerkschaft nach dem sich die Erwartungen die dort in CAFS (hier one-seven) gesetzt wurden weitgehend nicht erfüllt haben. Ganz ausdrücklich wird die mangelnde Leistung des Systems insbesondere bei Flüssigkeits- und Fahrzeugbränden erwähnt. Zumindest hier hätte ich mir einen Punktvorteil des DLS erwartet. Auch der Umweltaspekt wurde von dem Briten Steve Huggins thematisiert. Wenn die britischen Umweltbehörden Bedenken haben und Auflagen machen, dann ist es lediglich eine Frage der Zeit bis deutsche Behörden nachziehen. Es scheint als ob es schon sinnvollere Investitionen gegeben hätte.



Hi Reiner,

Obviously I have received your email!

The main problems we have had lately are reliability, with a number of
occasions of foam failure inside compartments. The cause of these
failures have been varied, from blocked filters, a design fault on how
the system was fitted to our appliances and a change in specification to
the hosereel which caused the hosereel to kink and restrict foam output.


Our advice would be to ensure a strict maintenance program and a good
installation design. We have found we have to inspect filters monthly
and often have to have them changed.

Regarding your concerns, we have ensured that 1:7 foam is only one of
the methods we use to firefight. Originally it was sold to us as the
only firefighting medium necessary but we have discovered over time that
it is of no use on vehicle fires and fuel fires, amongst others. It is
great to knock fires down but not so good at putting them out! We
frequently have to use water to fully extinguish the fire. As a result
we have 1 water hosereel, 1 foam hosereel and the normal water hose
deliveries.

Something that Schmitt may not tell you! We have discovered there is a
large environmental impact of the actual 1:7 foam. The English
Environmental Agency has insisted that when we train it does not enter
the water course, as it removes a lot of oxygen from water as the foam
decomposes. We have had to install special holding tanks on all our fire
stations at considerable cost. It seems we have to try and block drain
holes at incidents as well and let it decompose before it gets washed
away.

I hope this helps and is considered an act of international and
professional solidarity. I am on leave for the next 2 weeks and out of
the UK but will catch up on any further emails on my return.

I hope you manage to put a balanced view forward to any prospective
buyers and they don't get the same all round sales pitch as we both got.
It is a good tool but not the answer to everything.

Yours in Unity,

Steve Huggins
FBU Brigade Secretary for East Sussex
