What does holding Type III certification allow a technician to do when buying refrigerant from a supplier?
Correct Answer
D) Buy R-123 and other low-pressure refrigerant for the machines that technician services
Refrigerant subject to the sales restriction may be sold only to certified technicians, and the certification type sets what the technician may buy. A Type III card supports purchase of low-pressure refrigerant such as R-123 for the machines that card covers. It does not extend to high-pressure refrigerant, which belongs to Type II. Cylinder size and owner signatures have nothing to do with the restriction. The supplier keeps a record of the sale, so the card gets checked at the counter.
Why This Is the Correct Answer
The sales restriction limits refrigerant purchases to certified technicians, and a Type III card authorizes the low-pressure refrigerants that certification covers. Buying R-123 for a chiller you maintain is exactly what the card is for, and the supplier will record the certification when the sale is made.
Why the Other Options Are Wrong
Option A: Buy any refrigerant in any quantity, including high-pressure blends and pure refrigerants
A single type card does not open up every refrigerant. High-pressure refrigerant, whether blended or pure, is sold against Type II or Universal certification instead of Type III.
Option B: Buy refrigerant only in cylinders of twenty pounds or less at a time
No cylinder size limit is attached to the sales restriction. The rule governs who may buy refrigerant, not how the refrigerant is packaged or how much leaves in one trip.
Option C: Buy refrigerant only when the building owner signs the purchase order for the job
No owner signature appears anywhere in the rule. What matters is that the buyer is a certified technician and that the supplier keeps a record of the sale.
Memory Technique
Your card is your shopping list. Type III buys the vacuum family and nothing else.
Reference Hint
Refrigerant covered by the sales restriction may be sold only to certified technicians, and the certification type governs which refrigerant may be bought.
