The SNAP program could label refrigerant A as an acceptable substitute for a freezer but an unacceptable substitute for vending machines.

• A. True
• B. False
• C. Depends on the model
• D. Not specified

Answer: (A)

The SNAP program evaluates refrigerant substitutes for each end-use separately, not as a single blanket approval for all equipment. Because a refrigerant’s suitability depends on how it performs in a specific system, it can be acceptable in one appliance and not in another. For a freezer, refrigerant A might meet safety, compatibility, and efficiency requirements, while for vending machines it might raise concerns—such as different operating temperatures, pressure ranges, lubrication needs, electrical safety, or material compatibility—that prevent approval. So it’s possible for a refrigerant to be approved for a freezer but not for vending machines, making the statement true.
