1,2-Dibromotetrafluoroethane (C 2 Br 2 F 4) is a haloalkane. It is also known under codenames R-114B2 and Halon 2402. It is a colorless liquid with a boiling point of 47.2 °C. R-114B2 is occasionally used in fire suppression systems. It is highly volatile, passes through soil to air, and can be detected in the parts-per-quadrillion range.
Dibromodifluoromethane is a mixed halomethane. It is a colorless non-flammable liquid. Along with Halons 1211, 2402, and 1301, it is one of the most effective fire extinguishers, however, it is also very toxic. It is a class I ozone depleting substance (ODS).

Fire extinguisher. A stored-pressure fire extinguisher. A fire extinguisher is a handheld active fire protection device usually filled with a dry or wet chemical used to extinguish or control small fires, often in emergencies. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i ...
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
There was a faster phase-out of halon-1211, -2402, -1301, There was a slower phase-out (to zero by 2010) of other substances (halon 1211, 1301, 2402; CFCs 13, 111, 112, etc.) [contradictory] and some chemicals were given individual attention (Carbon tetrachloride; 1,1,1-trichloroethane).
