  1. A refrigerator's system pressure gauge reads 0 psig before recovery begins. This indicates:

    Answer: The system may have a leak and residual liquid refrigerant may still be present in the compressor oil

    Zero gauge pressure does not confirm the refrigerant is gone; liquid refrigerant dissolved in compressor oil can remain and must still be recovered.

  2. Which tool is specifically recommended for safely removing refrigerator compressor process tubes without releasing refrigerant to atmosphere?

    Answer: Self-tapping recovery valve (piercing valve)

    A self-tapping or piercing valve attaches to the process tube and allows refrigerant connection to recovery equipment without opening the system to atmosphere.

  3. Under the CAR certification program, what documentation must accompany a shipment of recovered refrigerant sent to a reclaimer?

    Answer: Bill of lading listing refrigerant type, quantity, and facility ID

    Recovered refrigerant shipments require a bill of lading identifying the refrigerant type, weight, and originating facility to ensure proper reclamation tracking.

  4. An electric range's bake element shows a visible crack. During dismantling, this element should be:

    Answer: Handled carefully and placed in a dedicated heating element collection for proper processing

    Cracked heating elements may contain magnesium oxide powder (an irritant) and should be handled carefully and collected separately for proper processing.

  5. When dismantling a room air conditioner containing R-22, the technician's EPA Section 608 certification must be at minimum which type?

    Answer: Type I (small appliances)

    Room air conditioners with factory-sealed refrigerant circuits qualify as small appliances under Section 608, requiring at minimum a Type I certification.

  6. A commercial ice machine contains R-404A refrigerant. Which recovery cylinder color code indicates it is safe to use for R-404A?

    Answer: Orange (the assigned color for R-404A)

    AHRI/ARI color coding assigns orange to R-404A recovery cylinders to prevent cross-contamination with other refrigerants.

  7. Which part of a residential clothes washer is classified as a mercury-containing component requiring separate handling?

    Answer: The lid switch or pressure switch (on older models)

    Some older washer lid switches and pressure switches used mercury tilt switches that must be removed and disposed of as universal waste.
