A shop technician certified Universal under Section 608 is sent to recharge the air conditioning in a customer's car, and stops at the supply house for a small cylinder of R-134a on the way. What does the sales restriction require of that purchase?
Correct Answer
C) Section 609 certification, which is what authorizes buying refrigerant for vehicle work
There are two sales restrictions running in parallel, one for stationary equipment and one for motor vehicle air conditioning, and each is tied to its own certification. Section 608 Universal is as broad as a stationary credential gets, and it still does not reach a car. Refrigerant intended for motor vehicle air conditioning may be sold only to technicians certified under Section 609. A technician who works on both kinds of equipment holds both credentials, which is common in fleet shops and in service businesses that cover vehicles and buildings.
Why This Is the Correct Answer
The purchase restriction that applies depends on what the refrigerant will be used in, not on how broad the buyer's other credentials are. Refrigerant for motor vehicle air conditioning is restricted to technicians certified under Section 609, so a Universal 608 certification does not qualify this technician to buy it. Holding both certifications is the normal answer for anyone working across the two worlds.
Why the Other Options Are Wrong
Option A: The Universal certification covers it, since Universal is the broadest 608 credential
Universal is the broadest certification within the stationary program, and its breadth stops at the boundary of that program.
Option B: No certification at all, since automotive refrigerant is sold over the counter freely
Refrigerant for motor vehicle air conditioning carries its own purchase restriction tied to Section 609 certification. It is not sold without regard to the buyer.
Option D: A written statement of intended use, which the wholesaler keeps with the sales record
A statement of intended use is not what the restriction asks for. The seller has to verify a certification, and the right certification here belongs to the vehicle program.
Memory Technique
Universal covers every building. It covers no vehicles.
Reference Hint
Refrigerant for motor vehicle air conditioning may be sold only to technicians certified under Section 609.
