Refrigerant Sales Restriction
The U.S. EPA instituted a refrigerant sales restriction on November 14, 1994.
Some information resulting from the restriction appears below.
Section 608 certified technicians may not buy “small cans”(containers filled with less than 20 pounds of R-12 or EPA-approved motor vehicle air conditioner substitutes, that contain an ozone-depleting substance).
Section 609 certified technicians may not buy R-22 in any size container because it’s an ozone-depleting refrigerant that isn’t intended for use in motor vehicle air
Buses that use R-22 refrigerant aren’t defined as motor vehicle air conditioners,
so Section 608 certification is required to service them.
