Fire suppression

From: Will Jeffers <wjeffers>
Date: Friday, September 10, 2004
In reading the MSDS's for Halon 1301, Novec 1230 and FM 200, I
notice that beneath the heading of reactivity data, all three of
these fire suppression products list hydrogen fluoride as a
hazardous decomposition product formed under conditions of high heat
or combustion.   I'm assuming that this means that if these clean
agents were used to extinguish a fire, a certain amount of hydrogen
fluoride would be generated.

Has anyone on the DistList been witness to an occasion where any of
these agents have been used to extinguish or suppress a fire?  If
so, was there any evidence of damage caused by hydrogen fluoride?
I'm particularly concerned with instances involving photographic
collections or reactive metal objects.
