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
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
