EPA Section 608 Technician Certification — Questions and Answers
Question 1: What must happen to refrigerant that is too contaminated for on-site recycling?
- It may be vented to the atmosphere if contamination exceeds 50%
- It must be destroyed immediately on-site
- It must be returned directly to the original refrigerant manufacturer
- It must be sent to an EPA-certified reclamation facility or destroyed (Correct answer)
Correct answer: It must be sent to an EPA-certified reclamation facility or destroyed
Highly contaminated refrigerant that cannot be adequately cleaned on-site must be shipped to an EPA-certified reclamation facility for processing to ARI 700 standards, or properly destroyed.
Question 2: What should an effective professional report include?
- As much raw data as possible without summary
- Only the data tables without interpretation
- Personal opinions without supporting data
- Clear objectives, methodology, findings, analysis, and actionable recommendations (Correct answer)
Correct answer: Clear objectives, methodology, findings, analysis, and actionable recommendations
An effective professional report includes clearly stated objectives, transparent methodology, organized findings, thorough analysis, and specific actionable recommendations.
Question 3: Which statement about the reuse of recovered refrigerant is TRUE under EPA 608?
- Recovered refrigerant can be returned to the same system or equipment owned by the same customer without further treatment (Correct answer)
- All recovered refrigerant must be tested and reclaimed before any reuse
- Recovered refrigerant can never be reused — it must be destroyed after recovery
- Recovered refrigerant can be sold to any buyer without meeting any purity standard
Correct answer: Recovered refrigerant can be returned to the same system or equipment owned by the same customer without further treatment
EPA 608 permits recovered refrigerant to be returned to the same system or other equipment belonging to the same customer without reclamation; only refrigerant sold to others must meet ARI 700 purity standards.
