IN addressing the type of foam, I suspect it is pretty much just
AFFF. Protein foam is a really old type that stinks to high heaven.
We actually had it at the plant I spent 5 yrs at (along with some
1952 Rockwood deluge valves activated by 220 vdc circuits). The
fluoroprotein I believe was an effort to improve the aromatic old
protein.

Hi All,
I don't know exactly when we should use AFFF, Fluoroprotein &
Protein foam concentrates, I know that all of them are intended for
class B hydrocarbon fuels and not suitable for use on fuels having
appreciable water solubility.
Would someone kindly let me know some special applications/
examples of AFFF, Fluoroprotein & Protein foam concentrates? Also I
would appreciate if explain some situations of using different
concentration, for example when we use 1% or 3% or 6% AFFF? What
applications/Examples?
Thanks in advance,
Reza
