Regulations & Safety第 70 / 240 题
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?
a.Anyone may buy any size container of stationary refrigerant
b.Sales of refrigerant for stationary use are restricted to EPA-certified technicians (or their employers), regardless of can size
c.Only 30-pound cylinders are restricted; small cans are unrestricted
d.Refrigerant sales have no restrictions at all
解析
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.
