Refrigeration technicians who violate the Clean Air Act can: - Lose their EPA
certification, be fined, be required to appear in Federal court.
After 1995, any supplies of CFC refrigerants to service existing units in the USA can
only come from: - recovery and recycling.
Refrigerant that is recovered can be returned to: - the same system or other
systems owned by the same person without restriction.
Refrigerant can not be called "reclaimed" unless it: - . has been chemically
analyzed and the refrigerant meets the ARI-700 standard.
The EPA can require a technician to demonstrate their ability to perform proper
procedures for recovering and/or recycling refrigerant. Failure to demonstrate
competency can result in: - revocation of the technicians certification.
What characteristic(s) of CFCs make them more likely to reach the stratosphere
than most other compounds containing chlorine? - Refrigerants that contain
chlorine but not hydrogen are so stable that they do not break down in the lower
atmosphere after being released. The chlorine or bromine reacts with the ozone,
causing it to change back to oxygen, thus destroying the ozone layer.
A system is considered dehydrated when: - the vacuum indicator shows you have
reached and held the required finished vacuum.

Disposable refrigerant containers are used for ______ virgin refrigerant
Which refrigerant is an HCFC? - R-123, R-124, R-22
What statement is true about an azeotropic refrigerant mixture? - It is a
mixture that acts like a single-component refrigerant over its entire range.
Chlorofluorocarbos (CFCs) and hydrochlorofluorocarbons (HCFCs) have which of
the following in common? - It is a mixture that acts like a single-component
refrigerant over its entire range.
To scrap a disposable cylinder, the internal cylinder pressure should be reduced to
at least: - 0 psig.
Manifold gauge sets are often color coded, when this is done, the high pressure
gauge is color coded: - Red.
In general, blended refrigerants should be charged: - as a liquid.
Blended refrigerants leak from a system: - in uneven amounts due to different
vapor pressures.
Which of the following gases help form the earth's protective shield? -
Stratospheric Ozone
, 3
In a refrigerant system, the device that changes a low pressure vapor to a high
pressure vapor is the: - compressor.
Data shows that chlorine in the stratosphere comes mainly from CFCs rather than
from natural sources such as volcanoes because: - The rise in the amount of
chlorine in the stratosphere matches the rise in the amount of fluorine, which has
different natural sources than chlorine; The rise in the amount of chlorine in the
stratosphere matches the rise in CFC emissions; Air samples taken from the
stratosphere over erupting volcanoes show that volcanoes contribute a small
quantity of chlorine to the stratosphere when compared to CFCs;
Which atom of the CFC molecule causes ozone depletion? - chlorine
The ozone layer protects the earth from: - ultraviolet radiation from the sun.
When using with any solvent, cleaner, chemical or refrigerant, you should review:
- material safety data sheets.
An award of up to what amount may be paid to a person supplying information
that leads to a penalty against a technician who is intentionally venting? - 10,000
The Montreal Protocol is: - a treaty among nations that controls production of
CFCs and HCFCs.
Which refrigerant is an HCFC? - R-123, R-22, R-124
