Refrigeration and Air Conditioning Regulations Flashcards

Which EPA program reviews substitute refrigerants and lists them as acceptable or unacceptable for specific end uses?

Answer: Significant New Alternatives Policy (SNAP)

The SNAP program evaluates substitutes for ozone-depleting substances by end use.

Which law passed in 2020 directs EPA to phase down U.S. production and consumption of HFCs by 85% by 2036?

Answer: The AIM Act

The American Innovation and Manufacturing (AIM) Act requires an 85% HFC phasedown by 2036.

On what date did production of HCFC-22 end in the United States, except for servicing equipment through recovered or reclaimed supply?

Answer: January 1, 2020

Production and import of virgin HCFC-22 ended January 1, 2020, so servicing now relies on recovered, recycled, or reclaimed R-22.

When leak testing a system, which gas mixture does EPA allow to be released without counting as a prohibited venting?

Answer: Nitrogen with a small trace amount of HCFC-22 used as a holding charge or tracer

Nitrogen with a trace of HCFC-22 used only for leak detection is not treated as a prohibited refrigerant release.

Which type of release is considered de minimis and is not a violation of the venting prohibition?

Answer: Small releases that happen during good-faith recovery using certified equipment and required practices

De minimis releases are small, unavoidable losses that occur while following required recovery and recycling practices.

Air conditioning on farm tractors and other off-road equipment, which is similar to motor vehicle air conditioning, may be serviced by technicians holding which certification?

Answer: Section 609 MVAC or Section 608 Type II

MVAC-like appliances may be serviced by technicians certified under either Section 609 or Section 608 Type II.

Under ASHRAE Standard 34, what does safety classification A1 mean for a refrigerant?

Answer: Lower toxicity, no flame propagation

A means lower toxicity and 1 means no flame propagation, which is the safest classification.
