When inspecting a refrigerator for recycling, which component must be checked for CFC content before processing?
Answer: Refrigerant in the sealed system
Refrigerant trapped in the sealed system must be identified and recovered because CFCs are ozone-depleting substances regulated under the Clean Air Act.
A quality control inspector finds a window air conditioner with a cracked compressor housing. What is the most critical immediate concern?
Answer: Potential refrigerant leak into the environment
A cracked compressor housing can release refrigerant, which is an ozone-depleting or greenhouse gas and must be contained before recycling.
Which standard is most commonly referenced when inspecting used appliances for hazardous material content in a US recycling facility?
Answer: EPA Section 608
EPA Section 608 of the Clean Air Act governs the handling, recovery, and recycling of refrigerants in appliances.
During incoming inspection, a technician notices a washing machine has a strong chemical odor. The correct first action is to:

An inspector identifies a chest freezer that uses R-600a (isobutane) as its refrigerant. What special handling precaution applies?
Answer: Handle with flammability precautions due to R-600a's combustible nature
R-600a is a flammable hydrocarbon refrigerant, requiring spark-free equipment and flammability precautions during recovery.
When performing a visual quality control check on a dehumidifier, which finding would cause an immediate rejection from the standard recycling stream?
Answer: Visible PCB-containing capacitors in damaged condition
Damaged PCB-containing capacitors are a hazardous waste requiring special handling and cannot enter the standard recycling stream.
