Good advice because it?s not nice to be near a fire. But I thought that Halon would only
amount to a few percent of the room volume, leaving plenty of oxygen. The operation
mechanism of Halon apparently isn?t oxygen displacement (while for nitrogen systems it
obviously is).
In general, it's fairly non-toxic, though it does cause things
like giddiness and other impairments. You don't want to be
high as a kite next to a machine fire. The other problem is
that in contact with very high temperatures (which, oddly
enough, are often found around fires), halon can break down
into some seriously nasty stuff like hydrofluoric acid. I think
I'd take my chances with the fire at that point.
