Halon was phased out starting 01/94. The last time I got quotes on any it was $20/lb.
Halon itself is nasty to breathe and under fire conditions makes a really nasty atmosphere.
Halon protected rooms like server rooms have a pre-alarm that gives a person 30 seconds or so to escape before the Halon releases.
Yep, I never wanted to be around when the Halon was activated.

Leaking refrigeration equipment and open flames are a bad combo. Phosgene is created when freon is burned. If you smell a chlorine/hydrochloric acid sort smell, run — there will also be phosgene.
