Isn't Halon toxic to humans?
It is if you breathe it in a high enough concentration, but it was banned because it was highly damaging to the ozone layer (a little research showed it's a type of CFC: http://en.wikipedia.org/wiki/Halon_1211
I was just researching this when I came across a Halon alternative (interestingly called "Halotron" - - sounds like the latest Transformer).
Pricey, but at least it's available:http://www.smokesign.com/2hafiex.html edited to correct some info ... This comment was edited on May 18, 2009, 15:23.
