We've done Halon dumps for initial testing after installation, and they
haven't thrown much stuff around, but it's still impressive.
The standards for Halon concentration say max 10%, min 5% for n minutes.
This is enough to put out the fire without killing you (at least not
rapidly.)  However, the stuff is heavier than air; unlike regular fire
situations, you SHOULD NOT CRAWL out of the room; stay up high where the
oxygen still is.
