Core (Universal)第 14 / 240 题
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.Only refrigerants in systems over 50 pounds
c.CFC and HCFC refrigerants and their non-exempt substitutes, including most HFCs
d.Only refrigerants used in automobiles
解析
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.
