A supply house offers small cans of R-134a to a walk-in DIY customer for a home refrigerator. Under Section 608 sales rules, what is the technician-buyer situation for such small-can HFC sales in stationary refrigeration?
Explanation
For stationary refrigeration and air conditioning, sales of substitute refrigerants such as HFCs are restricted to EPA Section 608-certified technicians or their employers, and this restriction is not waived just because the container is small. Only a narrow exception exists for very small cans of R-134a sold for motor vehicle air conditioning (which involves Section 609), not stationary equipment. A general DIY customer cannot buy restricted stationary refrigerant.
