 Chris, thanks for clarifying what I have no clue about  :-). I've also read
that its getting pretty expensive to get your hands on it because of
environmental issues. So, if I understand you correctly, its not toxic to
humans, and after firing it off in an enclosed space[cockpit].. we don't have
to worry about not being able to breath?
 
 
 Thanks for the help..
