CAR CAR Documentation & Chain of Custody 2

Question 1

Which piece of information from an appliance's data plate is MOST critical to record before beginning refrigerant recovery?

Accepted Answer

Refrigerant type and charge weight

Answer

Knowing the refrigerant type ensures the correct recovery equipment and cylinder are used, while the charge weight confirms when recovery is complete.

Question 2

A facility receives an appliance with a missing or unreadable data plate. The technician should:

Accepted Answer

Use a refrigerant identifier and record findings as 'unknown – identified as [type]' in the log

Answer

When the data plate is absent, a refrigerant identifier determines the actual type, which must still be recorded in the recovery log for regulatory compliance.

Question 3

In an appliance recycling manifest, the term 'gross weight of refrigerant recovered' refers to:

Accepted Answer

The total weight of refrigerant in the recovery cylinder including tare weight subtracted to find net refrigerant mass

Answer

Net refrigerant recovered is calculated by weighing the cylinder before and after recovery and subtracting the tare (empty cylinder) weight to determine actual refrigerant mass.

Question 4

NIST-traceable calibrated scales used for weighing recovered refrigerant at a CAR facility should be calibrated at minimum:

Accepted Answer

Annually, or per the manufacturer's recommended interval

Answer

Annual calibration (or per manufacturer schedule) ensures refrigerant weight records are accurate for both regulatory compliance and cylinder fill-level safety.

Question 5

A PCB-containing capacitor is discovered in a window air conditioner being recycled. The documentation requirement for its disposal is governed by:

Accepted Answer

EPA TSCA (Toxic Substances Control Act) regulations for PCB disposal

Answer

PCBs are regulated under TSCA, which requires tracking, labeling, and disposal through approved PCB disposal facilities with specific recordkeeping.
