Freon Definition
Many appliances we use every day contain chemicals that are harmful to the ozone layer, Earth's natural protection against the ultraviolet radiation from the sun. Refrigerators, freezers, window and car air conditioners are some examples of appliances that contain refrigerants commonly known as Freon.
Federal Law
The danger of Freon being released into the atmosphere prompted Congress to amend federal laws that prohibit the release of ozone-depleting refrigerants into the atmosphere. Since July 1, 1992, it has been a requirement that Freon be removed from appliances before they are disposed of.
