TW,
Regarding Halon. I heard when it was first outlawed that it is an ozone depleting chemical. I also heard that the oil companies used tons of it. If I remember right the reason they used it was they had to test their pumping stations. They would fill the pumping station with Halon when they would turn on the power, just in case there was any problems the station would not catch on fire.
Of course I coiuld be wrong, but that is what I remember.
