Historical Clean Agents - Halon 1301

Halon 1301, CF3Br, was developed by E.I. du Pont de Nemours and Company in the 1950s. It is a chemical agent by classification and is employed at design concentrations typically ranging from 5% to 7% by volume. This design concentration range corresponds to an agent mass requirement range of 2.1 to 2.9 lb/100 ft3 of protected volume (32.9 to 47.1 kg/ 100 m3 of protected volume). The bromine radical released upon decomposition is responsible for its classification. It is stored in the discharge cylinders as a liquid and is super-pressurized with nitrogen to either 360 psig (24.8 bar) or 600 psig (42 bar).

Halon 1301 is not toxic at its design concentration level. At 7.5% by volume, Halon 1301 did show evidence of cardiac sensitizationCardiac sensitization is an increased likelihood of heart arrhythmias upon exposure to the agent. Testing for this effect is performed by exposing dogs to an agent:air mixture after being administered adrenalin..
