I thought halon was "harmless" to people, but mixing halon with fire produces nasty poisons. The vast majority of fire suppression events I've heard of (in a DC or similar environment) are unintentional, meaning the halon wouldn't be toxic (according to my potentially flawed memory). Certainly, if there's been a legit fire suppression event, you wait for people with the hard-hats to clear the facility. Of course, you should do the same if there's been a no-fire suppression event, but ideally your fire suppression mechanism doesn't kill the people in the room needlessly...
