Perhaps if you've seen the promotional films with people still in a raging
(simulated) shipboard engine room fire that was published by Dupont (I think)
when Halon 12 was adminstered you'd realized that it didn't replace the
oxygen.  You are right about the chlorine though as this stuff was declared an
ozone depleter and consequently is banned from use just like Freon R-12,
another Dupont product.  Too bad, it was the best extinguishing agent known,
especially for someone trapped in a race car, racers breath too.
