CFC CFC Refrigerant Reclamation & Recycling Standards 2 — Questions and Answers
Question 1: What is the maximum allowable oil content in reclaimed refrigerant per AHRI Standard 700?
- 0.1% by weight
- 0.5% by weight (Correct answer)
- 1.0% by weight
- 2.0% by weight
Correct answer: 0.5% by weight
AHRI Standard 700 limits oil content in reclaimed refrigerant to 0.5% by weight (5,000 ppm) to ensure system compatibility and performance.
Question 2: What is the primary reason to send refrigerant to a certified reclamation facility rather than simply recycling it on-site?
- Reclamation facilities charge lower fees than on-site equipment rental
- To restore the refrigerant to new-product purity specifications per AHRI 700 (Correct answer)
- Because on-site recycling equipment is illegal
- To comply with state disposal regulations only
Correct answer: To restore the refrigerant to new-product purity specifications per AHRI 700
Off-site reclamation at a certified facility is necessary to achieve the AHRI 700 purity levels required for the refrigerant to be resold or reused in different equipment.
Question 3: What must happen to refrigerant that cannot be reclaimed to AHRI 700 purity standards?
- It must be vented safely to the atmosphere
- It must be destroyed (Correct answer)
- It must be stored indefinitely in certified cylinders
- It can be used only in commercial applications
Correct answer: It must be destroyed
Refrigerant that is too contaminated to be reclaimed to AHRI 700 standards must be destroyed using an approved destruction method.
Question 4: How must cylinders containing recovered refrigerant be labeled when shipped to a reclamation facility?
- Only with the technician's name and date of recovery
- With DOT-required hazmat labels and identification of the refrigerant as used or potentially contaminated (Correct answer)
- With a green 'recyclable' sticker only
- No labeling is required for recovered refrigerants
Correct answer: With DOT-required hazmat labels and identification of the refrigerant as used or potentially contaminated
DOT regulations require that cylinders containing recovered or potentially contaminated refrigerants be properly labeled with hazmat markings and identified as used product.
Question 5: Under EPA rules, who bears primary responsibility for ensuring that reclaimed refrigerant meets AHRI 700 purity standards?
- The original equipment owner
- The technician who recovered the refrigerant
- The EPA-certified reclaimer (Correct answer)
- The refrigerant distributor
Correct answer: The EPA-certified reclaimer
The EPA places responsibility for certifying that reclaimed refrigerant meets AHRI 700 standards on the EPA-certified reclamation facility that processed it.
Question 6: What is the maximum allowable non-condensable gas content in reclaimed refrigerant per AHRI Standard 700?
- 0.5% by volume
- 1.5% by volume (Correct answer)
- 3.0% by volume
- 5.0% by volume
Correct answer: 1.5% by volume
AHRI Standard 700 limits non-condensable gases (such as air and nitrogen) in reclaimed refrigerant to 1.5% by volume to prevent head pressure problems in equipment.
