Bulley,
I have for my employer's new building purchased about 40 new hand-held
extinguishers this past year.  Four were for special use areas.  They were
to replace existing Halon type units.  The brand name is 'Clean Guard'.
They are cleaner to use and they are advertised not to wipe a computer out.
Bicarbonate type cause a lot of cleanup and side damage.  CO2 is our first
choice but should not be used in a closed room because of suffocation
possibilities.  CO2 on an engine fire is not recommended because it will
accelerate a magnesium fire. The main problem with Halon type devices is not
so much Ozone damage as the formation of phosgene (read WW1 poison gas)in a
fire.  Also they will displace the oxygen in a closed room event.  A
self-contained breathing unit is required in this circumstance.  Personally,
I prefer to carry in the van a small CO2 unit.  The judgement must be that
if there is a fire involving magnesium it's too late unless you have massive
foam agents.
Hope this is helpful.
Regards,
Eckie Prater
