1. The use and release of CFCs and HCFCs has a far reaching effect on
________. VERIFIED ANSWERa. 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
___________. VERIFIED ANSWERa. 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: VERIFIED ANSWERa. 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
__________________. VERIFIED ANSWERb. 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? VERIFIED ANSWERa. 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 _________. VERIFIED
ANSWERa. 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? VERIFIED
ANSWERd. 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: VERIFIED ANSWERc. 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: VERIFIED ANSWERc. 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: VERIFIED
ANSWERb. 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 __________. VERIFIED ANSWERa. 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: VERIFIED ANSWERc. Low
loss fittings that can be manually closed or close automatically when
hose are disconnected to minimize the refrigerant loss.
