EPA Exam Version B32
A disposable cylinder ought to be decreased to what strain before scrapping? - ANS-zero psig
A refrigerant label to discover the kind of refrigerant recovered is positioned on restoration
cylinders for all the following reasons, EXCEPT to: - ANS-Tell if the cylinder is safe.
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HFCs) and hydrofluorocarbons (HFCs)
have which of the following in common? - ANS-they must be recovered before establishing or
getting rid of home equipment
How do refrigerant blends leak from a gadget? - ANS-At uneven quotes due to one-of-a-kind
vapor pressures
How do the global warming potentials of isobutane (R-600a), propane (R-290), and R-4414
examine to the GWPs of HFC-134a, R-404A, and R-410A? - ANS-they're substantially decrease
How does the worldwide warming potential of R-410A compare to that of carbon dioxide? -
ANS-It is thousands of times more
In the event of a huge launch of CFC, HCFC, or HFC refrigerant in a contained place which of
the following is genuine? - ANS-Self-contained breathing equipment (SCBA) or leaving the
place is needed.
In what state does the refrigerant depart the condenser? - ANS-excessive pressure liquid
Under EPA's regulatons, what fashionable ought to rechined refrgerantmeet earlier than it is
able to be resold? - ANS-AHRI seven hundred

refrigerant has been eliminated from family fridges before they are disposed of? - ANS-very last
individual in the disposal chain
What are the characteristics of hydrofluoroolefins (HFOS)? - ANS-Non-ozone depleting, and
have a low global warming potentials
What effect will low ambient temperatures have on healing? - ANS-Increase the recuperation
time
