Bromochlorodifluoromethane was introduced as an effective gaseous fire suppression agent in the mid-1960s. BCF was also widely used in the maritime industries and transport industries. Its efficiency as a fire extinguishing agent has also led it to be the predominant choice of fire extinguishing agent on commercial aircraft.

Other names of BCF includes Halon 1211 and Freon 12B1.
