EPA 608 TYPE 3 EXAM 2026/ 2027
UPDATED EXAM WITH VERIFIED
SOLUTIONS.
1. A recovery cyclinder which is 1/2 full of recovered R-410A @
90*F, in the absence of non-condensables will be presurized
to: - correct answer -300 psig.
2. When using ______, it is essential to take extra measures
(heating/striking), to help release trapped refrigerant from the
compressor oil. - correct answer -passive system-dependdent
recovery devices on a small appliance with a non-operating
compressor.
3. According to the EPA which recovery equipment maintenance
practice(s) should be preformed on a regular basis? - correct
answer -check recovery device for refrigerant leaks
4. On a small appliance with an operating compressor that has a
completely plugged capillary tube, what is the minimum number
of access valves that are needed to evacuate the refrigerant -
correct answer -1 valve on the high side
, Page | 2
5. Which refrigerant is most commonly used as a replacement for
R-12 in new household refrigerators - correct answer -R-134a
6. Small amounts of refrigerant have no odor, therefor a pungent
odor is detected during a system recovery &/or repair: - correct
answer -a compressor burn-out has likely occurred
7. If R-22 or R-12are exposed to high temperatures, these
refrigerants can decompose to form: - correct answer -
hydrochloric & hydroflouric acids
8. Large spills of refrigerant can cause suffocation because: -
correct answer -they are heavier than air & displace oxygen
9. In the event of a large release of R-12 or R-22 in a contained
area - correct answer -you should wear a "SCBA" or leave the
area is required
, Page | 3
10. If a large leak of refrigerant occurs in an enclosed area 7 no
self-contained breathing apparatus is available then you should
- correct answer -Vacate & ventilate the spill area
11. Portable refillable tanks or containers used to ship recovered
refrigerants must meet what standards - correct answer -DOT
12. Recovery or recycling equipment whaich was manufactured
after 11-15-93 and is used to recover refrigerant from small
appliances prior to the disposal of the small appliance must be
used: - correct answer -recover 80% of the refrigerant if the
compressor isn;t working and 90% on one with a working
compressor
13. EPA regulations require the capture of at least 80% of the
refrigerant from a small appliance with an non operating
compressor is the tech is using: - correct answer -either type of
recovery unit
14. A standard vacuum pump designed for evacuation &
dehydration can: - correct answer -be only used as a recovery
device in combination with a non pressurized container
