WITH VERIFIED ANSWERS LATEST
UPDATE!!PASSED!!
All recovery devices manufactured BEFORE November 15, 1993 for use with small
appliances must meet which of the following requirements - Answer-Capable of

EPA certified in refrigerant recovery
EPA rules require capture of 80% of the refrigerant from a small appliance sealed
systems with a non-operating compressor if technicians are using - Answer-A system
dependent (passive) process
When using nitrogen in repairing a sealed refrigeration system with a nitrogen tank you
should always be equipped with a - Answer-Regulator
If a large leak of refrigerant occurs such as from a field cylinder in an enclosed area
what action should be taken when no self-contained breathing apparatus is available -
Answer-Vacate and ventilate the spill area
Portable refillable tanks or containers used to ship CFC or HCFC refrigerant obtained
with recovery equipment must meet what standards - Answer-Department of
transportation DOT

cylinder - Answer-Must be recovered
, When filling a charging cylinder refrigerant that is vented off the top of the cylinder -
Answer-Must be recovered regardless of the refrigerant
Which of the following refrigerants is most commonly used as a replacement for R-12 in
new household refrigerators - Answer-134a
When a household refrigerator compressor does not run it is recommended that low and
high side access valves be installed when recovering refrigerant from the system
because - Answer-It can enhance the speed of recovery
It may be necessary to achieve required recovery efficiency
Both A and B
When installing any type of access fitting onto a sealed system - Answer-The fitting
should be leak tested before proceeding with recovery
Which of the following is not a method or device presently used for monitoring the 80%
fill level in a recovery tank - Answer-Sight glass

Answer-Never be used as a recovery device in combination with a pressurize container
Before shipping any used refrigerant in a cylinder is necessary to - Answer-Properly
label the refrigerant container
Properly complete shipping paperwork
Check that the refrigerant container meets department of transportation standards
All of the above
Which refrigerants can be mixed - Answer-None of the above
When used solderless type piercing valves should not remain installed On refrigeration
systems after completion of repairs because - Answer-They tend to leak overtime
A storage cylinder of recovered R-12 at normal room temperature (about 75°F) in the
absence of non-combustible's will be pressurized to - Answer-75 psig
Portable refillable tanks or containers used to ship CFC or HCFC refrigerants obtained
with recovery equipment must meet what standards - Answer-Department of
transportation DOT
The system dependent (passive) recovery process - Answer-Recovers refrigerant in a
non-pressurized container
