EPA 608 WITH ACCURATE SOLLUTIONS
1. The use and release of CFCs and HCFCs has a far reaching effect on ________. -
correct Answers-a. the stratosphere
The introduction of CFCs and HCFCs has dramatically changed our lifestyles. Little did
we know that the use and release of these compounds into the atmosphere would have
far reaching effects on our environment. The greatest effect is in the stratosphere, far
removed from the Earth's surface. (Page 1 EPA's prep manual)
2. When a chlorine atom meets with an ozone molecule, it takes one ___________. -
correct Answers-a. oxygen atom from the ozone
When a chlorine atom meets with an ozone molecule, it takes one oxygen atom from
the ozone. (Page 1 EPA's prep manual)
3. R-11 is a: - correct Answers-a. CFC
Based on EPA's definition of CFC, R-11 is classified as a CFC. (Page 1 EPA's prep
manual)
4. ODP is a measurement of CFCs and HCFCs ability to __________________. -
correct Answers-b. destroy the ozone
Ozone Depletion Potential (ODP) is a measurement of CFC's and HCFC's ability to
destroy ozone. CFCs have been found in air samples taken from the stratosphere. The
chlorine in these compounds is the culprit. (Page 1 EPA's prep manual)
5. How many miles high is the stratosphere? - correct Answers-a. 10 to 30
The stratosphere is the Earth's security blanket. It is located between 7 and 30 miles
above sea level and is comprised of, among other things, ozone. (Page 1 EPA's prep
manual)
6. To take refrigerant out of a system, it must be _________. - correct Answers-a.
recovered
To remove refrigerant in any condition from a system and store it in an external
container is to recover it. (Page 2 EPA's prep manual)
7. The body of a recovery cylinder must be in what color? - correct Answers-d. Gray
Approved refrigerant recovery cylinders can easily be identified by their colors,
YELLOW TOPS AND GRAY BODIES. (Page 4 EPA's prep manual)
8. R-134A is a: - correct Answers-c. HFC
Based on EPA's definition, R-134A is classified as a HFC. (Page 1 EPA's prep manual)
, 9. Technicians servicing small appliances must be certified in refrigerant recovery if
they: - correct Answers-c. Perform sealed system service.
Technicians servicing small appliances except motor vehicle air conditioning (MVAC)
must be certified in refrigerant recovery if they perform sealed system service. (Page 6
EPA prep manual)
10. The EPA definition of a small appliance includes: - correct Answers-b. Products
manufactured, charged, and hermetically sealed in a factory with 5 pounds of refrigerant
or less.
The EPA definition of a small appliance includes products manufactured, charged, and
hermetically sealed in a factory with five pounds of refrigerant or less. (Page 6 EPA prep
manual)
11. Recovery equipment manufactured after November 15, 1993, must be __________.
- correct Answers-a. certified by an EPA laboratory
Recovery equipment manufactured after November 15, 1993, must be certified by an
EPA approved testing laboratory, (example, U.L. or E.T.L) as capable of recovering
90% of the refrigerant if the compressor is operating, 80% of the refrigerant if the
compressor is not operating, or achieving a 4 inch vacuum under the conditions of ARI
740. (Page 6 EPA prep manual)
12. All equipment must be equipped with: - correct Answers-c. Low loss fittings that can
be manually closed or close automatically when hose are disconnected to minimize the
refrigerant loss.
All equipment must be equipped with low loss fittings that can be manually closed, or
close automatically, when hoses are disconnected to minimize the refrigerant loss.

13. What is the EPA requirement for leak repair for small appliances? - correct
Answers-a. Leaks should be repaired whenever possible.
The EPA does not require leak repair for small appliances, but leaks should be repaired
whenever possible. (Page 6 EPA prep manual)
14. Before beginning a refrigerant recovery procedure, it is necessary to know: - correct
Answers-c. The type of refrigerant that is in the system.
Before beginning a refrigerant recovery procedure, it is necessary to know the type of
refrigerant that is in the system. (Page 6 EPA prep manual)
15. If a reclamation facility receives a tank of refrigerant, they will _____________. -
correct Answers-d. refine to new refrigerant specifications
RECLAIM is to process refrigerant to a level equal to new (virgin) product specifications
as determined by chemical analysis. RECLAIMED refrigerant must meet the standard
set forth in ARI 700 before it can be resold. (Page 2 EPA prep manual)
16. Self-contained (active) recovery equipment has ______________. - correct
Answers-b. to use its own compressor for recovery
