Ozone Layer Protection
The ozone layer is a natural part of our atmosphere. It acts like a protective sun screen by blocking harmful ultraviolet (UV) rays from the sun.
Certain chemicals—such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons—can damage the ozone layer. These can cause holes to form in the layer and allow more UV rays to reach the earth’s surface. Increased exposure to UV rays is dangerous for people, animals, and plants.
Chemicals that damage the ozone layer, known as ozone-depleting substances (ODS), are used as refrigerants in:
- commercial, home and vehicle air conditioners, and refrigerators,
- foam blowing agents,
- solvents,
- aerosol spray propellants,
- fire extinguishing agents, and
- chemical reactants.
To protect the ozone layer from these chemicals, we must also prevent the release of ozone-depleting substances to the atmosphere. Whenever possible, we must also replace them with safer alternatives.
In Prince Edward Island, we are working to prevent the release of ozone-depleting substances. Installers and service persons who handle and purchase these chemicals must be licensed, qualified in their trade, and participate in environmental awareness training.
