Core (Universal)Question 14 of 240
Since November 15, 1995, it has been illegal to knowingly vent which refrigerants during service, maintenance, or disposal?
a.Only CFC refrigerants such as R-12
b.CFC and HCFC refrigerants and their non-exempt substitutes, including most HFCs
c.Only refrigerants used in automobiles
d.Only refrigerants in systems over 50 pounds
Explanation
The venting prohibition originally covered CFCs and HCFCs, and effective November 15, 1995 it was extended to their non-exempt substitutes, which includes most HFCs such as R-410A and R-134a. It is not limited to CFCs, automotive systems, or large systems. Only a small number of substitutes that EPA has specifically exempted may be released, and even then good practice is to avoid venting.
