[Histonet] COBr2

Carbonyl bromide is not [repeat NOT] uses as an ingredient in fire
extinguishers! Carbonyl bromide is an extremely toxic, low boiling liquid
(boils at 140 degrees F).  
Some fire extinguishers contain Halon 1301 or Halon 1211 which can be
converted to carbonyl bromide by very hot fires (temperatures over 1000
degrees F).  This restricts their use to very small fires.
Since carbonyl bromide is currently classified as a "war gas", it may be
hard to buy.  (Carbonyl bromide is chemically and toxicologically similar to
phosgene, which the British used to great effect in WWI.)

Type "carbonyl bromide" into google and see the results. Seems it is an 
ingredient in fire extinguishers.
