- Ozone Depleting Substance ("ODS")
An Ozone Depleting Substance ("ODS") is an artificial compound and scheduled substance that has been proven to adversely affect the earth’s protective ozone layer. Typical ozone depleting substances include;
- chlorofluorocarbons (CFCs)
- halon
- carbon tetrachloride (CCl4)
- methyl chloroform (CH3CCl3)
- hydrobromofluorocarbons (HBFCs)
- hydrochlorofluorocarbons (HCFCs)
- methyl bromide (CH3Br)
- bromochloromethane (CH2BrCl)
The main uses of ozone depleting substances include:
- HCFCs and halons in fire extinguishers;
- CFCs and HCFCs in refrigerators and air conditioners;
- CFCs and HCFCs in expanding foam;
- CFCs and HCFCs as aerosol propellants;
- methyl bromide for fumigation of soil, structures and goods to be imported or exported.
