After what date is it illegal to vent HFCs?

The correct answer is November 15th, 1995. This date is significant because it marks the beginning of strict regulations regarding the venting of hydrofluorocarbons (HFCs) under the Clean Air Act. The aim of these regulations is to protect the environment by minimizing the release of substances that can contribute to ozone depletion and global warming. Venting HFCs is prohibited because these refrigerants are potent greenhouse gases, and managing their emissions is essential for combating climate change. Understanding this regulation is crucial for technicians, as it emphasizes the importance of responsible handling and disposal of refrigerants.
