equipment. ✔✔15
Anytime pressurized nitrogen is put into the system, the nitrogen gas ✔✔Maybe vented to the
ambient air
When a tank of mixed refrigerant is sent to a reclaimer, they can ✔✔Either refuse to except the
refrigerant or charge extra for processing it

heat and strike the compressor with a rubber mallet to release any refrigerant. ✔✔Passive
recovery devices on a small appliance with a non-operating compressor
You must know the ________ before beginning a refrigerant recovery. ✔✔Type of refrigerant
that is in the system
Nitrogen tanks should always be equipped with a ________. ✔✔Pressure regulator and pressure
relief valve downstream of the regulator
If a large leak of refrigerant occurs, __________. ✔✔Immediately vacate in naturally ventilate
the area
A very large refrigerant leak can cause Suffocation because refrigerants ✔✔Are heavier than air
and displace oxygen
Always _____________ when connecting or disconnecting refrigeration hoses. ✔✔1.) wear
safety eyewear and butyl-lined gloves 2.) verify the hoses are rated for the refrigerant being used
3.) avoid trapping liquid refrigerant in the hoses

When filling a charging cylinder with a regulated refrigerant; ✔✔The refrigerant vapor that is
vented off the top of the cylinder must be recovered.
Which of the following is true regarding refrigerant leaks one small appliances? ✔✔EPA does
