- VERIFIED Q&A - MOST RECENT VERSION 2026
As technicians, we must remain current with federal, state, and local laws.
How many questions will you be given for the universal certification?
ANSWER 100
ANSWER 70%: What is the passing mark for all EPA certifications?
Whether true or not, you should commit all regulations to memory because they
will never change. ANSWER False
Can natural resources like volcanoes provide chlorine for the environment?
ANSWER : Yes, however they are not the main source.
True or false: The sun's damaging UV rays are reflected and absorbed by
ground level ozone. ANSWER False
How does ozone depletion impact people? ANSWER : Higher risk of cataracts
and skin cancer
Is there proof that the stratosphere contains refrigerants? ANSWER : Yes.
How many ozone molecules may be destroyed by one chlorine molecule?
ANSWER 100,000
There are ____ oxygen atoms in ozone. ANSWER 3
The troposphere contains the majority of the ozone, true or untrue. ANSWER
untrue
ANSWER : 300,000 ozone molecules can be destroyed by three chlorine
molecules.
Ozone's primary role in the stratosphere is to absorb and reflect ultraviolet
radiation from the sun.
,ANSWER Human emissions of refrigerants such as CFCs and HCFs are the
main source of chlorine in the stratosphere.
ANSWER : Chlorine is the chemical that damages the ozone layer.
ANSWER : Reduced crop yields and a hazard to wild and marine life are two
consequences of the ozone layer's depletion.
Who is impacted by ozone depletion? ANSWER : People worldwide
Can equipment still retain refrigerant after it has been phased out? ANSWER :
Yes.
Can technicians service equipment that contains that refrigerant once it is
phased out? ANSWER Yes
Where can technicians get refrigerant to service equipment that uses it after it
has been phased out? Response from refrigerant that has been recovered or
reclaimed
Is it possible to resell refrigerant? ANSWER : Yes, but only after it has been
recovered in accordance with AHRI Standard 700 requirements.
To recover which refrigerants, equipment must be approved to EPA standards.
ANSWER Cfc hcfc hfc
Who can you sell to if you are selling R-22 refrigerant? ANSWER A
technician or company with an EPA 608
Can you use recovered R-22 refrigerant in a different person's device?
ANSWER : Yes, but only if it is reclaimed and complies with AHRI 700
requirements.
When all CFCs are phased out in the United States - ANSWER 1995
When r22 and r124b are phased out in the US - ANSWER 2020
When will all HCFCS be phased out in the US? ANSWER 2030
What documentation is required for R22? ANSWER : Type, dates, and quantity
of refrigerant
The EPA Clean Air Act's Section 608 is a federal legislation.
, State and municipal laws—which may be more stringent—must be complied
with in accordance with federal law.
Because of the venting ban, you must recover the impacted refrigerant before
opening, maintaining, and discarding equipment.
The last person in the disposal chain is in charge of making sure that all
refrigerant is eliminated before disposing of equipment that contains it,
according to section 608 standards.
Which appliances are subject to section 608 regulations? ANSWER Freezers
ANSWER Important New Alternatives Policy: What does snap stand for?
How much does it cost to violate the Clean Air Act? ANSWER 44539 per day
The Montreal Protocol: What is it? - ANSWER A global accord involving 197
nations
Section 608's objective is to safeguard the ozone layer and control substances
that cause ozone depletion.
What is SNAP's objective? ANSWER : To supply substitute refrigerants,
support CAA objectives, and take into account the impact of substitute
refrigerants on both people and the environment.
Considering that refrigerant A is ozone depleting, what should you do if you
find out that you have refrigerant B in a system that contains refrigerant A?
ANSWER : Recover the combination in a different recovery cylinder.
Before discarding equipment that includes CFCs, HCFCs, or their replacement,
the following steps must be taken: ANSWER Recover the refrigerant
If technicians violate the Clean Air Act, they may be subject to fines, federal
charges, and loss of their EPA 608 certification.
What constitutes a de minimis discharge of refrigerant? ANSWER : When
hoses with low loss fittings are disconnected due to catastrophic equipment
failure, refrigerant is released.
ANSWER Water, nitrogen, and carbon dioxide are examples of refrigerants
that are not covered by section 608 refrigerant management rules.
