What date was the sale of CFCs and HCFCs restricted to technicians certified in refrigerant recovery?

• A. November 14, 1994
• B. November 15, 1993
• C. October 22, 1995
• D. December 1, 1992

Answer: (A)

The sale of CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons) was restricted to technicians certified in refrigerant recovery starting on November 14, 1994. This regulation was established as part of the efforts to reduce ozone-depleting substances under the Clean Air Act amendments. The regulation aimed to ensure that only qualified technicians, who understood the correct handling and recovery procedures, could purchase these substances to prevent their release into the atmosphere. This certification requirement plays a critical role in environmental protection and highlights the importance of proper refrigerant handling in compliance with federal regulations.

While the other dates listed pertain to various milestones in refrigerant management and regulation, they do not specifically mark the introduction of the restriction that mandates certification for the sale of these substances.
