Answer 2

The restriction on the sale of Class I and Class II refrigerants to certified technicians by an EPA-approved program took effect after November 14, 1994, due to environmental concerns like ozone depletion.

Step-by-step explanation:

Environmental regulation refers to the imposition of limitations or responsibilities on individuals, corporations, and other entities for the purpose of preventing environmental damage or improving degraded environments. The sale of Class I and Class II refrigerants will be restricted to technicians certified by an EPA-approved program after November 14, 1994. This regulation was implemented following concerns about the depletion of the ozone layer, which protects the Earth from potentially damaging ultraviolet light.

Chlorofluorocarbons (CFCs), which were widely used as refrigerants and in aerosol sprays, were found to be especially harmful because they neutralize the ozone's ability to block UV rays. Consequently, international initiatives like the Kyoto Protocol were established to address such global environmental issues.
