Bromotrifluoromethane (also known as Halon 1301 ) is a chemical compound that has been used as refrigerants and fire extinguishing agents. It was introduced in the 1960s as a fire suppressant. Bromotrifluoromethane extinguishes fires at a concentration of 6%, by interfering with the free radical reaction of the combustion. Which belongs to the group of halogenated hydrocarbons compound was classified as harmful to the ozone layer in the Montreal Protocol. Your production is in developed countries, including in the European Union prohibited. The application, however, is still allowed under international law.

The gas is also included with a volume fraction of about 2.5 and a mass fraction of about 13 ppt in the air.

Safety

At high concentration, the gas having a suffocating effect. Case of combustion or heating the gas to decompose such as fluorine and hydrogen bromide in corrosive and toxic fluorine and bromine compounds.
