In what year did venting CFC and HCFC refrigerants become unlawful?

• A. 1992
• B. 1993
• C. 1990
• D. 1989

Answer: (A)

Venting refrigerants to the atmosphere is prohibited to prevent release of ozone-depleting substances and greenhouse gases. The regulations governing this were established under the Clean Air Act amendments, and the specific prohibition on venting CFC and HCFC refrigerants became effective in 1992. This means technicians must recover refrigerants during service, disposal, and major repairs using approved recovery equipment rather than venting them. Other years don’t align with the start of that formal prohibition, which is why 1992 is the best answer.
