Document Summary
Chemicals that are non-toxic, non- flammable and contain atoms of carbon, chlorine and fluorine are known as chlorofluorocarbons (cfcs). This chemical is used to manufacture aerosol sprays, blowing agents for foams and packing materials as solvents, as well as refrigerants. In 1920, freon was a miracle compound since it saved many lines. Freon is colourless, odourless, non-flammable, and non-corrosive and can be either in liquid or gas state. With a rising of concern for environmentally friendly products, the concern for the use of chlorofluorocarbons, or freon is shunned as it is notorious for adding to the depletion of the earth"s ozone layer. Since it has ozone-depleting potential (odp), cfcs are now recognized as. To eliminate the production and consumption of any ozone-depleting subtances, the montreal protocol requires parties to reduce the production and consumption and any trades relating to these substances. Import and export of cfcs in canada have been prohibited since january.
