A CAR facility receives 50 refrigerators in one shipment. What sampling approach is acceptable for refrigerant verification if full testing is not feasible?
Answer: Apply a statistically representative sampling plan with documentation
CAR protocols allow statistically representative sampling plans, but all results must be documented to demonstrate due diligence.
Which instrument is used to verify that refrigerant has been fully recovered from an appliance before shredding?
Answer: Electronic refrigerant leak detector or system pressure gauge
A refrigerant leak detector or pressure gauge confirms the system has been evacuated to the required low-pressure threshold before mechanical destruction.
What does a 'manifest' document serve in the context of appliance recycling quality control?
Answer: It tracks the chain of custody and material flow from receipt to final disposition
A manifest provides a chain-of-custody record ensuring all materials, especially hazardous ones, are tracked from intake to final recycling or disposal.
A quality inspector finds mercury-containing switches in a range being processed. What is the correct disposition?
Answer: Remove and consolidate them for mercury recycling through a certified mercury reclaimer
Mercury switches must be removed and sent to a certified mercury reclaimer under EPA Universal Waste rules to prevent environmental contamination.
A refrigerator is delivered that still contains food residue and mold. Before QC inspection proceeds, what should happen?
Answer: Clean the unit in a designated wash area with proper PPE
Biohazardous residue must be cleaned in a designated area with appropriate PPE before standard QC inspection to protect worker health.
During QC, an inspector finds that a dryer's drum still contains clothing. What is the most appropriate first step?
Answer: Remove and properly dispose of or donate the clothing before processing
Non-appliance materials must be removed before recycling to prevent contamination of material streams and ensure accurate weight reporting.
Which of the following best describes the purpose of a 'hold tag' in a recycling facility's quality control process?
Answer: It flags a unit that requires additional inspection or resolution before further processing
A hold tag is a quality control tool that temporarily stops processing on a unit until a specific issue is investigated and resolved.
