Bromochlorodifluoromethane, also known by the trade name
Halon 1211, or
BCF, or
Halon 1211 BCF, or
Freon 12B1, is a
haloalkane with the chemical formula is
CF2ClBr.
Brominated haloalkanes were first used during World War II as
fire extinguisher for aircraft and
tanks. Bromochlorodifluoromethane was introduced as an effective
gaseous fire suppression agent around 1973 for use around highly valuable materials in places such as
museums,
mainframe rooms and telecommunication
switching centers. They were also widely used in the maritime industries in the engine rooms of ships. Its advantages as a fire extinguishing agent was that it had lower toxicity than chemicals such as
carbon tetrachloride and that since it was a
covalently bonded compound, it didn't form conductive ions which made it usable on electrical equipment.
The production of bromochlorodifluoromethane and similar
chlorofluorocarbons 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%).
