Fatal accidental inhalation of bromochlorodifluoromethane (Halon 1211).

Bromochlorodifluoromethane (Halon 1211) is a widely used fire extinguishing agent. Several cases of sudden death in teenagers associated with BCF abuse have been reported. BCF is used as a fire extinguisher in battle tanks. Two young previously healthy male soldiers were accidentally exposed to BCF in a battle tank. The tank driver died, but the gunner survived the event with no medial complications. It is concluded that BCF should be used in confined chambers only after the evacuation of all personnel.
