Mayf, list:

It is true that halon will smother humans, in high concentrations.  One of
my first engineering assignments was to design a halon supression system for
a computer room.  It's the only one I ever did-- and it was a long time
ago-- but I do remember that there was a fairly broad range of halon/ air
mixture percentage wherein the fire would be supressed, but the people would
not.  The key to system design was to choose the correct volume of halon to
mix with the air in the computer room.  Too little, and the fire would not
be supressed; too much, and the geeks would not survive.  These principles
were widely accepted among fire-suppression specialists at that time; I just
learned from them, and did what they were doing.

I think the removal of the halon bottles you mentioned may have been simply
the result of chlorofluorocarbons falling into disfavor.

When I was at Boeing, We used those big bottles of Halon for our dedicated
computer rooms. However, they just disappeared. I think it was because that
anyone trapped inside a room and the system let go, would lead to
death.Stuff is a smotherant. I think they decided that replacing computers
was cheaper than replacing people. I think...but this has been a while.
