Halon Fire Extinguisher

This Halón "1301" system was installed by the Coast Guard to protect the Control Room against electrical fire.

Halón systems used gaseous fire extinguishing agents known as "halogenated fluorocarbons" which are a mix of bromine, fluorine, chlorine, and carbon. They protected computer rooms and important electric equipment in many industrial and office environments against very costly fires.

If a Coast Guard technician saw a fire in the room he would pull the lever on the opposite wall. The Halón flooded the room and extinguished the fire.

Halón systems were eliminated because they were found to contribute to the depletion of the earth's protective ozone layer.
