ODP ODP Recovery and Recycling 1 — Questions and Answers
Question 1: Under EPA Section 608, technicians must recover refrigerant before opening or disposing of systems containing how much refrigerant?
- Any amount (Correct answer)
- More than 5 lbs
- More than 50 lbs
- More than 100 lbs
Correct answer: Any amount
EPA Section 608 requires refrigerant recovery before servicing or disposing of any appliance regardless of the amount of refrigerant it contains.
Question 2: Which EPA certification type is required for technicians who service small appliances containing CFCs or HCFCs?
- Type I (Correct answer)
- Type II
- Type III
- Universal
Correct answer: Type I
EPA Type I certification is required for technicians who service small appliances with five pounds or less of refrigerant.
Question 3: What is the primary difference between refrigerant 'recovery' and refrigerant 'recycling'?
- Recovery removes refrigerant; recycling cleans it for reuse on-site (Correct answer)
- Recovery destroys refrigerant; recycling recharges systems
- Recovery measures purity; recycling measures pressure
- There is no difference — the terms are interchangeable
Correct answer: Recovery removes refrigerant; recycling cleans it for reuse on-site
Recovery means removing refrigerant from a system into an external container, while recycling means cleaning that refrigerant for reuse without meeting ARI 700 purity standards.
Question 4: Which organization sets the purity standard (ARI 700) that reclaimed refrigerant must meet before it can be resold?
- Air-Conditioning, Heating, and Refrigeration Institute (AHRI) (Correct answer)
- Environmental Protection Agency (EPA)
- Occupational Safety and Health Administration (OSHA)
- American Society of Heating Engineers (ASHE)
Correct answer: Air-Conditioning, Heating, and Refrigeration Institute (AHRI)
AHRI Standard 700 specifies the purity levels that reclaimed refrigerant must meet to be sold as virgin-equivalent product.
Question 5: When recovering refrigerant from a system with a non-operating compressor, which recovery method is most appropriate?
- Passive recovery using system pressure differential
- Push-pull recovery method (Correct answer)
- Liquid recovery only
- Vapor recovery using the system compressor
Correct answer: Push-pull recovery method
The push-pull method is most effective for inoperative systems because it simultaneously pushes liquid and pulls vapor without relying on the system's own compressor.
Question 6: What document must accompany refrigerant sent to a reclaimer to prove its origin and contents?
- Refrigerant transfer certificate or chain-of-custody form (Correct answer)
- EPA technician certification card
- MSDS sheet only
- Manufacturer warranty card
Correct answer: Refrigerant transfer certificate or chain-of-custody form
A refrigerant transfer certificate or chain-of-custody form documents the source, quantity, and type of refrigerant being sent for reclamation.
