Section 608 regulations · EPA 608 Core. The correct answer, and the reasoning behind it.

Pressure classes, recovery equipment certification, AHRI 700, the sales restriction and the venting ban.

The question

Which refrigerant sale is allowed to an uncertified buyer under the sales restriction?

• AA 30-pound cylinder of R-22 for a homeowner's own heat pump
• BA small MVAC can (2 lb or less) with a self-sealing valveCorrect answer
• CA 25-pound cylinder of R-410A bought for a home window unit
• DRecovered R-134a sold directly to a neighbor

Why “A small MVAC can (2 lb or less) with a self-sealing valve” is correct

40 CFR 82.154(c)(1)(ix) exempts non-exempt substitute refrigerant intended for MVACs that is sold in containers of two pounds or less with a unique fitting and, for newer cans, a self-sealing valve. Other refrigerant sales require a certified buyer.

Why the other answers are wrong

• A 30-pound cylinder of R-22 for a homeowner's own heat pump — R-22 for stationary equipment may be sold only to certified technicians or their employers.
• A 25-pound cylinder of R-410A bought for a home window unit — R-410A cylinders for stationary equipment fall under the sales restriction.
• Recovered R-134a sold directly to a neighbor — Used refrigerant cannot be sold to a new owner without reclamation, and the buyer must be certified.
