Core (Universal)第 20 / 240 题
A parts counter clerk is asked to sell a 25-pound cylinder of R-410A to a walk-in customer. Under Section 608 sales restrictions, the clerk may sell it only to someone who:
a.Pays in cash and shows a driver's license
b.Promises not to vent the refrigerant
c.Is an EPA Section 608 (or 609) certified technician, or a certified technician's employer
d.Owns the home where the system is installed
解析
Since January 1, 2018, sales of HFC and other substitute refrigerants are restricted to EPA-certified technicians (or their employers or wholesalers), the same rule that already applied to ozone-depleting refrigerants. Paying cash, promising not to vent, or owning the home does not qualify a buyer. The clerk must verify the buyer's certification before completing the sale.
