Tetrachloromethane, Carbon Tetrachloride
Tetrachloromethane is primarily used as chemical feedstock in the synthesis of CFCs, HCFCs and HFCs. All other uses are currently prohibited.
Tetrachloromethane has an 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 January 1st, 1995, the manufacture, import and export of CFCs has been prohibited in Canada, except for use as feedstock, as analytical standards, in chlor-alkali plants or for essential uses.
