Halon was used back in the day for fire suppression but I thought it was only dangerous at high enough concentrations to suffocate you by displacing oxygen.

To be of any use, it also has to suffocate a fire.

Halon doesn't work that way, by displacing oxygen.

Flame chemistry is weird. Halogenated fire suppression agents work by making Hydrogen (!) out of free radicals.
