  1. During the dismantling of a chest freezer, a technician notices the polyurethane foam insulation is yellowed and brittle. This is most likely an indicator of:

    Answer: CFC blowing agent has off-gassed over decades of use

    Yellowing and brittleness in aged polyurethane foam indicates CFC blowing agents have migrated out over time, though residual CFCs may still be present.

  2. When using a power shear to dismantle appliance sheet metal, which PPE item is most critical beyond safety glasses and gloves?

    Answer: Cut-resistant sleeves rated ANSI A4 or higher

    Sheet metal edges and flying shards during power shearing create severe laceration risks requiring cut-resistant arm protection rated ANSI A4 or higher.

  3. A dehumidifier built before 2010 should be assessed for which refrigerant before recovery?

    Answer: R-22 (chlorodifluoromethane)

    Many dehumidifiers manufactured before 2010 used R-22, a Class II ODS that requires certified recovery under Section 608.

  4. When dismantling a top-load washer, the transmission/gearcase assembly should be handled as:

    Answer: An oil-containing component requiring drain-before-shred protocol

    Washer transmissions contain gear oil that must be drained to prevent soil contamination and is handled as used oil under RCRA.

  5. What is the purpose of a 'parts washer' station in a certified appliance recycling facility?

    Answer: To remove grease and refrigerant oil from recovered metal scrap

    Parts washers remove residual oils and grease from dismantled metal components to improve scrap quality and reduce contamination at downstream smelters.

  6. Which component in a residential dishwasher is most likely to contain a small amount of radioactive material?

    Answer: The turbidity sensor

    Some older dishwasher turbidity sensors used Am-241 (americium) as a radiation source, similar to smoke detectors.

  7. Before shredding refrigerator units, EPA regulations require that refrigerant recovery achieve what minimum efficiency?

    Answer: 95% of the system charge

    EPA Section 608 regulations for MVACs and appliances require recovery to a level that achieves at least 95% recovery of the refrigerant charge.
