If you added up all the "damage" to the ozone layer due to Halon
Discharge I wonder if it would come close to the damage done by the excess
exhaust expelled by the various vehicles used by the Halon banners in the
average election campaign.

For a time I was with the US Army Corps of Engineers in Alaska and was
heavily
involved in the construction of a central electronics facility. Scores of
computers in the same space, elevated computer floors, grounded,
electrically
insulated walls, back-chatter filters in the electrical system, , all
connected
into NORAD in Colorado. During construction, there was a massive, positive
pressure Halon fire suppression system installed. The system was designed to
positively displace all oxygen when discharge occurred. The fire drill
program
was, in part, designed agound the fact that in minutes after fire
suppression
system discharge there was going to be no air to breathe. It was a good
trick
to get a hundred people out of there standing up, but it was done.
Halon was evidently ok to use with electronics.
