Since what date has it been illegal to vent substitutes for CFC and HCFC refrigerants?

The correct answer is that it has been illegal to vent substitutes for CFC and HCFC refrigerants since November 15, 1995. This date marks a significant milestone in environmental regulations concerning refrigerants, which are linked to ozone layer depletion.

The prohibition against venting these substitutes was put in place to protect the environment, specifically targeting ozone-depleting substances. As the use of refrigerants that contribute to ozone depletion was phased out, regulations tightened around the handling and disposal of newer refrigerants too. The 1995 regulation serves as a pivotal point in the efforts to reduce harmful emissions into the atmosphere.

Understanding this law is essential for technicians working with refrigerants, as it underlines the importance of proper refrigerant recovery practices and compliance with federal regulations designed to mitigate environmental damage.
