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.Is an EPA Section 608 (or 609) certified technician, or a certified technician's employer
c.Promises not to vent the refrigerant
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.
