Type I — Small AppliancesCâu 87 / 240
A scrap yard receives old household refrigerators and vending machines for crushing. Before the units are disposed of, who is responsible for ensuring the refrigerant is recovered?
a.Only the original manufacturer of the appliance
b.The homeowner who discarded the unit
c.Nobody, because small appliances are exempt from recovery at disposal
d.The last person in the disposal chain must recover the refrigerant or verify it was already recovered
Giải thích
For small appliances headed to disposal, the person who takes the final step in the disposal chain (such as a scrap recycler) must recover any remaining refrigerant or confirm through a signed statement that it was already properly recovered. Refrigerant may never be knowingly vented during disposal. This closes the loop so refrigerant is not released when appliances are crushed.
