I find myself thinking of other side effects 
Bromochlorodifluoromethane
Halon 1211 is a trade name for Bromochlorodifluoromethane. It is also known as BCF,Halon 1211 BCF, or Freon 12B1. The chemical formula is CF2ClBr.
It was introduced as an effective gaseous fire suppression agent in the 1960s for use around highly valuable materials in places such as museums, mainframe rooms, and telecommunication switching centers. The production of Bromochlorodifluoromethane and similar Chlorofluorcarbons has been banned in most countries since January 1, 1994 as part of the Montreal Protocol on ozone depleting substances.
This is a volatile extinguishant that should be used only with a breathing apparatus (when volume exceeds 5%).
I have this distinct recollection of BCF being phased in by the RAF in the 60's to replace the old ones which contained something whose name escapes me, but which was much prized as a dry cleaning agent leading to lots of empty fire extinguishers.
Can anyone recall its name?
Probably wrong but the following come to mind as "dry cleaning agents" but I don't know if they were used in Fire Extinguishers.
Tetrachloroethylene. Also known as perchloroethylene (Perc)
Another I recall was CFC 113, a chlorofluorocarbon solvent.
There was something that was marketed, in a little jar with a cloth pad under the screw off lid ... Dabitoff was it's trade name. I think the active ingredient was called something like Carbon-tetrachloride.
