EPA 608 Type I Practice Test 8

This test focuses on the difference between recovery, recycling, and reclaiming refrigerant, using small-appliance scenarios. It covers which process is required for disposal, which allows reuse on the same job, and which is the only legal path to resell refrigerant to a new owner.

The EPA 608 certification is required by law for any technician who purchases or handles refrigerants. It covers safe handling, leak detection, recovery, and environmental regulations.

Type I covers small appliances (≤5 lbs refrigerant), Type II covers high-pressure systems, Type III covers low-pressure systems, and Universal covers all three. Most HVAC technicians pursue Universal certification.

You must score at least 70% on each section of the exam. The Universal exam has four parts: core, Type I, Type II, and Type III.

Type I Exam Tip: Recovery just removes and stores. Recycling cleans it on-site for the same owner. Reclaiming purifies it to AHRI Standard 700 at a certified facility, the only process that allows resale to a new owner.

EPA 608 Type I Practice Test 8 — Question List

Question 1: What does "recovery" mean when talking about refrigerant?

Removing refrigerant from a system and storing it
Selling refrigerant to a new customer
Purifying refrigerant to a certified purity standard
Venting refrigerant safely into the outdoors

Question 2: What does "recycling" mean when talking about refrigerant?

Cleaning refrigerant on-site for reuse, still by the same owner or on the same job
Purifying refrigerant to AHRI Standard 700 at a certified facility
Venting refrigerant into the atmosphere
Selling refrigerant to any new customer

Question 3: What does "reclaiming" mean when talking about refrigerant?

Simply storing refrigerant in a cylinder
Venting refrigerant to reduce pressure
Processing refrigerant to AHRI Standard 700 purity at a certified facility
Reusing refrigerant without any processing at all

Question 4: A technician removes refrigerant from a broken vending machine and stores it in a cylinder, with no cleaning or processing. What is this called?

Reclaiming
Recycling
Reselling
Recovery

Question 5: A technician removes refrigerant from a refrigerator, filters it on-site, and puts it back into the same unit after a repair. What is this process called?

Recovery
Recycling
Reclaiming
Reselling

Question 6: Refrigerant recovered from several appliances is sent to a certified facility, where it is purified to AHRI Standard 700 so it can be sold to a new customer. What is this process called?

Recovery
Recycling
Reclaiming
Venting

Question 7: True or False: Refrigerant that has only been recovered, with no further processing, can legally be sold to a new owner.

True, recovery alone is enough for resale
True, as long as the cylinder is labeled
True, if the refrigerant is R-134a
False, only reclaimed refrigerant may legally be resold to a new owner

Question 8: True or False: Refrigerant that has been recycled on-site can be sold to a brand-new customer who was not part of the original job.

True, recycled refrigerant can always be resold
True, as long as it passes a visual inspection
True, if it is recycled twice
False, recycled refrigerant is limited to the same owner or job

Question 9: Which of the three processes, recovery, recycling, or reclaiming, requires a certified facility?

Recovery
Recycling
Reclaiming
None of them require a certified facility

Question 10: Before a small appliance can be scrapped, which of the three processes is the minimum legally required step?

Recovery
Recycling
Reclaiming
All three are required before disposal

Question 11: A technician recovers refrigerant from a broken refrigerator, filters it, and puts it into a replacement refrigerator for the same customer, on the same job. What best describes this process?

Reclaiming, because the refrigerant is reused
Recovery, because refrigerant was removed from a system
Recycling, because it was cleaned on-site for the same owner
Venting, because refrigerant left the original system

Question 12: Why can refrigerant that has only been recovered not simply be sold as-is to a new owner?

It has not been purified or certified to a resale purity standard, which only reclaiming provides
Recovered refrigerant is always contaminated with air only
It is against the law to store refrigerant in any cylinder
Recovered refrigerant loses its chemical identity

Question 13: Of the three processes, which one is the simplest, involving no cleaning or purity testing at all?

Recovery
Recycling
Reclaiming
They are all equally complex

Question 14: What is the maximum refrigerant charge for a hermetically sealed system to qualify as Type I?

10 pounds
5 pounds or less
20 pounds
50 pounds

Question 15: What passing score applies to the open-book Type I exam?

70%
60%
84%
50%

Question 16: What recovery efficiency must system-dependent recovery reach when the compressor is running?

70%
80%
100%
90%

Question 17: What recovery efficiency must self-contained recovery equipment reach when the compressor is dead?

90%
80%
50%
65%

Question 18: Which small-appliance refrigerant is flammable and requires spark-free recovery tools and equipment?

R-134a
R-600a
R-12
R-22

Question 19: True or False: A small appliance can be disposed of without any recovery step, as long as recycling and reclaiming are not needed.

True, recovery is optional if recycling is not needed
True, only reclaiming is legally required before disposal
True, disposal has no refrigerant-related requirements
False, recovery is always required before disposal

Question 20: Why must refrigerant be recovered before a technician brazes a sealed line?

Leftover refrigerant can break down into toxic byproducts, like phosgene gas
It has no effect on safety
It only matters for reclaimed refrigerant
It prevents the joint from cooling too fast

Question 21: Who is legally allowed to purchase Class I and Class II refrigerants?

Only certified technicians
Any adult customer
Only appliance recyclers
Only certified facility managers

Question 22: What protective gear should a technician wear while recovering refrigerant, regardless of whether it will later be recycled or reclaimed?

No protection is needed
Eye and skin protection
A hard hat only
Ear plugs only

Question 23: Since what date has it been illegal to knowingly vent HFC refrigerants, instead of recovering them?

July 1, 1992
November 15, 1995
January 1, 1990
November 15, 1993

Question 24: A technician holds only Type I certification. Does this allow the technician to recover refrigerant from a central split-system air conditioner?

Yes, Type I covers all recovery work
No, Type I only covers small-appliance work
Yes, as long as the refrigerant is later reclaimed
Yes, since recovery has no certification requirement

Question 25: Who needs Type I certification to legally recover refrigerant from a small appliance?

Anyone who services, maintains, repairs, or disposes of hermetically sealed small appliances
Only technicians who work at certified reclaiming facilities
Only technicians who never recycle refrigerant
No one, small appliance recovery is unregulated

Study Tip: The EPA 608 exam is closed book. Memorize: recovery is required before opening any refrigerant system. Venting refrigerant is illegal. Know the ODP and GWP values for R-22, R-410A, R-134a, R-32, and R-454B.
