2. Recover any remaining refrigerant and then render the cylinder useless, then recycle the
metal is the proper disposal method for: disposable cylinders.
3. Silicone elastomers, for use in seals and gaskets, are not compatible with which
refrigerants: HFOs.
4. What is the Significant New Alternatives Policy (SNAP) Program: EPA's. program that
identifies refrigerants with lower overall risks to human health and the environment.
5. Clean refrigerant for reuse by separating the oil from the refrigerant and removing
moisture from the refrigerant by passing it through one or more filter driers, is the
definition of: Recycle.
6. HCFCs contain: Hydrogen, Chlorine, Fluorine, and Carbon.
7. Before shipping any used refrigerant cylinders, check that the cylinder meets what
standards: DOT.
8. How much can a person be fined per day per violation for knowingly releasing a
regulated substance that violates the Clean Air Act? $44,539.
9. A refrigerant cylinder designed to hold recovered refrigerant has a: Grey body & a yellow
top.
10. Which of the following has the highest Ozone Depletion Potential: CFCs.
11. Which international agreement (Treaty) regulated the production and use of CFCs,
HCFCs, halons, methyl chloroform and carbon tetrachloride? Montreal Protocol.
12. Reusable refrigerant containers under high-pressure must be hydrostatically tested how
often: 5 years.
13. Crop loss, eye disease, and skin cancer have been attributed to: Depletion of
Stratospheric ozone.
14. The compressor: changes a low-pressure vapor to a high-pressure vapor.
15. Which type of refrigerant contains no chlorine: HFCs.
16. To process refrigerant to a level equal to new (virgin) product specifications as
determined by chemical analysis defines: Reclaim.
17. HFCs: will not damage stratospheric ozone, but have a high GWP.
18. The condenser: changes a high-pressure vapor to a high-pressure liquid.
19. Which of the following refrigerants is an HFO: R-1234ze.
20. The chlorine in CFCs and HCFCs: Will not dissolve in water.
21. The molecule found in CFCs and HCFCs that depletes ozone is: Chlorine.

safe pressure for: leak testing.
25. Which ASHRAE classification means slightly flammable: A2L.




Type I
1. System-dependent or passive recovery equipment: Captures refrigerant into a non-
pressurized container.
2. If regulations change after the technician becomes certified: The technician is responsible
for complying with any changes to the regulations.
3. When filling a charging cylinder with a regulated refrigerant: The refrigerant vapor that is
vented off the top of the cylinder must be recovered.
4. If a strong odor is detected while performing a refrigerant recovery process: A
compressor burnout has likely occurred.
5. Which of the following is an example of a non-condensable: Air.
6. When using a system-dependent recovery system on an appliance that has an operating
compressor, the technician should: Run the compressor and recover from the high side of
the system only.
7. Small appliances in recreational vehicles may use refrigerants such as Ammonia,
Hydrogen, and water. These refrigerants: should not be recovered
8. Recovery equipment must be: Certified by an EPA-approved testing laboratory.
9. Type I Certification is required for: Persons handling refrigerant during maintenance,
service, or repair of small appliances.
10. When pressurizing a system with nitrogen you should: Both B & C.
11. With a non-operating system compressor, recovery equipment must be capable of
recovering: 80 percent of the refrigerant or achieving 4 inches of vacuum.
12. Applying heat, with a heat gun, to the compressor: Can help vaporize any trapped liquid
refrigerant during recovery.
13. Which of the following is true regarding refrigerant leaks on small appliances: EPA does
not require repair, but leaks should be repaired whenever possible.
14. System-dependent recovery methods may only be used on appliances containing: 15
pounds of refrigerant or less.
15. Which HC refrigerant is allowed for use in NEW Domestic Small Appliances: R-600a.
16. A small appliance is defined by EPA as: Appliances manufactured, charged, and
hermetically sealed in a factory that contain 5 lbs or less of refrigerant.
17. Self-contained or active recovery equipment: Has its own means to recover refrigerant.
18. When a system is in deep vacuum: never energize the compressor.
19. Technicians who perform sealed-system service on small appliances must have: Type 1 or
universal certification.
20. Small appliances are equipped with a straight piece of tubing (process stub) that is used:
As the installation location for a piercing-type access valve.
