Dibromotetrafluoroethane is halon-2402. Halons are organic, synthetic (i.e., human-made) chemicals. They are found in fire protection applications, due to their effectiveness as fire extinguishing agents. However,dibromotetrafluoroethane has a high ozone-depleting potential (ODP); thus, it is identified as an ozone-depleting substance (ODS).

Canada is a Party to the Montreal Protocol on Substances that Deplete the Ozone Layer, which requires Parties to gradually phase-out production and consumption of ODS, as well as reduce and eliminate trade in these substances. Since July 1st, 1994, the manufacture, import and export of Halon 2402 has been prohibited in Canada, except for essential uses or for use as analytical standards.
