When is it illegal to vent CFCs or HCFCs?

The illegal venting of CFCs (Chlorofluorocarbons) and HCFCs (Hydrochlorofluorocarbons) is established in regulations that came into effect as part of the Montreal Protocol and subsequent U.S. regulations to phase out ozone-depleting substances. The correct date when it became illegal to vent these substances is July 1, 1992.

This regulation was a crucial step in addressing environmental concerns about ozone depletion, as both CFCs and HCFCs have significant harmful impacts on the ozone layer which protects the Earth from harmful ultraviolet radiation. The enforcement of this date emphasizes the legal obligation for technicians and companies handling these substances to manage them responsibly, preventing their release into the atmosphere.

Other choices do not accurately reflect the implementation date of these regulations. Understanding the timeline is essential for compliance and environmental stewardship in refrigerant management.
