1. EPA 608 Certification is required for individuals who handle refrigerants in the United States.
• A. True
• B. False
• C. Only for Type I technicians
• D. Only for appliance owners
Correct Answer: A. True
Rationale: Section 608 of the Clean Air Act requires any person who maintains, services, repairs, or
disposes of appliances containing regulated refrigerants to hold EPA Section 608 certification. This
applies to technicians across all equipment types and sizes, not just appliance owners or a single
certification category.
2. Type I Certification is for servicing small appliances containing refrigerants.
• A. True
• B. False
• C. Only for automotive air conditioning
• D. Only for industrial chillers
Correct Answer: A. True
Rationale: Type I certification covers small appliances manufactured, charged, and hermetically
sealed with 5 pounds or less of refrigerant, such as household refrigerators, freezers, and window air
conditioners. It does not cover automotive (Section 609) or large industrial systems.
3. Type II Certification is for servicing high-pressure refrigerants, typically used in commercial
applications.
• A. True
• B. False
• C. Only for low-pressure chillers
• D. Only for small appliances
,Correct Answer: A. True
Rationale: Type II certification covers high-pressure refrigerants such as R-410A, R-22, and R-134a
used in commercial and residential split systems, rooftop units, and heat pumps. Type III, not Type II,
covers low-pressure refrigerants.
4. Type III Certification is for servicing low-pressure refrigerants, often found in chillers.
• A. True
• B. False
• C. Only for high-pressure systems
• D. Only for small appliances
Correct Answer: A. True
Rationale: Type III certification covers low-pressure refrigerants such as R-11, R-123, and R-113,
commonly used in centrifugal chillers. These systems operate below atmospheric pressure and
require specialized handling procedures.
5. Universal Certification allows the holder to work with all types of refrigerants.
• A. True
• B. False
• C. Only Type I and Type II
• D. Only Type II and Type III
Correct Answer: A. True
Rationale: Universal certification is earned by passing all three Type I, Type II, and Type III exams. It
authorizes the technician to service any appliance covered under EPA Section 608, making it the
most comprehensive credential.
6. Refrigerant Recovery is the process of removing refrigerant from a system to prevent its release
into the atmosphere.
• A. True
• B. False
• C. Only for disposal
• D. Only for recycling
Correct Answer: A. True
, Rationale: Recovery is the first step in refrigerant handling and is required by EPA regulations before
opening a system. It prevents ozone-depleting and greenhouse gases from escaping into the
atmosphere during service or disposal.
7. Recycling is the process of cleaning and reusing refrigerants after recovery.
• A. True
• B. False
• C. Only for CFCs
• D. Only for HFCs
Correct Answer: A. True
Rationale: Recycling involves removing contaminants, moisture, and acids from recovered refrigerant
so it can be reused in the same or another system. It is distinct from reclamation, which requires
chemical analysis to meet AHRI 700 purity standards.
8. A Recovery Device is equipment used to remove refrigerants from appliances.
• A. True
• B. False
• C. Only for small appliances
• D. Only for automotive systems
Correct Answer: A. True
Rationale: Recovery devices, such as recovery machines and vacuum pumps, are designed to extract
refrigerant from systems and store it in recovery cylinders. EPA sets performance standards for
recovery equipment based on appliance type and refrigerant.
9. Leak Detection is the use of methods to identify leaks in refrigeration systems.
• A. True
• B. False
• C. Only for large systems
• D. Only for low-pressure systems
Correct Answer: A. True
Rationale: Leak detection is required under EPA regulations to minimize refrigerant loss. Common
methods include electronic leak detectors, ultrasonic detectors, soap bubbles, and fluorescent dyes.
Regular leak inspections are mandated for appliances above certain charge sizes.
