EPA 608 609 - EPA Refrigerant Handling Certification EPA 608 Type I Practice Test 1 — Questions and Answers
Question 1: Under EPA Section 608, the term 'small appliance' for Type I certification is defined as equipment that is fully manufactured, charged, and hermetically sealed with how much refrigerant?
- 5 pounds or less (Correct answer)
- 10 pounds or less
- 15 pounds or less
- 20 pounds or less
Correct answer: 5 pounds or less
EPA regulations define small appliances (Type I) as fully manufactured, charged, and hermetically sealed systems containing 5 pounds or less of refrigerant. This distinguishes them from larger systems covered under Type II and Type III certifications.
Question 2: Which of the following pieces of equipment would fall under Type I EPA 608 certification requirements?
- A rooftop commercial HVAC unit
- A window-unit air conditioner with a self-contained hermetic compressor (Correct answer)
- A chiller system in a large office building
- A split-system residential heat pump
Correct answer: A window-unit air conditioner with a self-contained hermetic compressor
A window-unit air conditioner with a self-contained hermetic compressor qualifies as a small appliance under Type I because it is fully manufactured, factory-charged, and hermetically sealed with 5 pounds or less of refrigerant.
Question 3: When recovering refrigerant from a Type I small appliance using a system-dependent (passive) recovery method, the technician must recover refrigerant to what level before opening the system?
- 0 psig
- 4 inches of mercury vacuum (Correct answer)
- 10 inches of mercury vacuum
- 15 inches of mercury vacuum
Correct answer: 4 inches of mercury vacuum
For system-dependent recovery on small appliances where the compressor is operational, the EPA requires the technician to recover refrigerant to 4 inches of mercury vacuum before opening the system for repairs or disposal.
Question 4: Who is exempt from EPA Section 608 refrigerant recovery requirements when disposing of small appliances like household refrigerators?
- Licensed HVAC contractors only
- Individuals who purchase the appliance for personal use and dispose of it themselves (Correct answer)
- Any technician certified under Type II
- No one — all persons must comply
Correct answer: Individuals who purchase the appliance for personal use and dispose of it themselves
EPA regulations exempt individuals who purchase small appliances for personal use (e.g., homeowners discarding their own refrigerator) from recovery requirements. However, commercial entities and technicians must still comply with recovery rules.
Question 5: Which refrigerant has been commonly used in older small appliances such as refrigerators manufactured before the mid-1990s, making proper recovery especially important due to its ozone depletion potential?
- R-410A
- R-32
- R-12 (Correct answer)
- R-134a
Correct answer: R-12
R-12 (CFC-12) was the standard refrigerant in older household refrigerators and small appliances before the phase-out under the Montreal Protocol. It has significant ozone depletion potential (ODP of 1.0), which is why proper recovery is critical.
Question 6: A technician recovers refrigerant from a Type I small appliance and wants to reuse it in another similar system. What must be done with the recovered refrigerant before it can be legally recharged into a different owner's equipment?
- It can be recharged directly without any processing
- It must be recycled or reclaimed to ARI 700 purity standards (Correct answer)
- It must be destroyed by an EPA-approved facility
- It must be tested for moisture content only
Correct answer: It must be recycled or reclaimed to ARI 700 purity standards
Recovered refrigerant that will be used in a different owner's equipment must be reclaimed to ARI 700 standards by a certified reclaimer. Simply recycling on-site is only acceptable when recharging the same system or a system owned by the same owner.
