- AReturn it to any refrigerant supplier
- BRelease it to the atmosphere
- Send it to a certified reclaimer or dispose of properly
- DUse it in another system
Correct answer
Send it to a certified reclaimer or dispose of properly
Why
Contaminated refrigerant must be sent to a certified reclaimer for processing or properly disposed of - never vented or reused without reclaiming.
The concept behind this question
Recover, recycle and reclaim are three distinct things and the exam tests whether you know the difference. Recovering means removing refrigerant from an appliance and storing it, with no processing. Recycling means cleaning it for reuse — typically oil separation and a filter-drier pass — usually on site. Reclaiming means reprocessing it to meet the AHRI 700 purity specification, which requires laboratory analysis and can only be done by a certified reclaimer, not in the field.
