Core Concepts
This federal law regulates refrigerants and ozone depletion.
What is the Clean Air Act?
Venting refrigerant into the atmosphere is ________.
What is illegal?

What is R-22?
This certification is required for small appliances under 5 lbs.
What is Type I?
This PPE protects your eyes from refrigerant exposure.
What are safety glasses?
This type of refrigerant contains chlorine and has high ozone depletion potential.
What is a CFC?
This machine is used to remove refrigerant from a system.
What is a recovery machine?
This refrigerant replaced R-22 in many modern systems.
What is R-410A?
This certification covers high-pressure systems like residential AC.
What is Type II?
Refrigerant can cause this injury when it contacts skin.
What is frostbite?
This organization sets the rules for refrigerant handling certification.
What is the EPA (Environmental Protection Agency)?
This is the maximum fill level for a recovery cylinder.
What is 80%?
This term refers to a refrigerant’s impact on global warming.
What is GWP (Global Warming Potential)?
This certification covers low-pressure systems like chillers.
What is Type III?
In confined spaces, refrigerant can cause this life-threatening condition.
What is asphyxiation?
This term describes the ability of a refrigerant to damage the ozone layer.
What is ODP (Ozone Depletion Potential)?
Before opening a system, refrigerant must be removed using this process.
What is recovery?
This type of refrigerant contains no chlorine and does not deplete ozone.
What is an HFC?
This certification allows work on all system types.
What is Universal Certification?
Heating a refrigerant cylinder can cause this dangerous event.
What is an explosion?
This refrigerant classification has zero ozone depletion potential but still contributes to global warming.
What is an HFC?
This condition can slow recovery because refrigerant is trapped and continues to boil off.
