1. Which agency regulates hazardous waste disposal in the United States? → Environmental Protection Agency (EPA)
2. A worker is splashed in the eyes with compressor oil. The immediate first aid response is to: → Flush eyes continuously with water for at least 15 minutes
3. When a Certified Appliance Recycler professional discovers a regulatory violation, what is the appropriate action? → Report it through proper channels immediately
4. Porcelain enamel coatings on appliance surfaces are made by fusing which base material onto steel? → Inorganic glass frit
5. An inspector is reviewing a facility's corrective action records after a refrigerant release incident. Which element is most critical to include? → Root cause analysis and steps taken to prevent recurrence
6. Which law requires businesses to properly dispose of electronic waste? → Electronic Waste Recycling Act
7. What is a fundamental principle of Blueprint Reading & Interpretation in Certified Appliance Recycler practice? → Following established standards and best practices
8. An appliance recycler's stormwater permit requires a Pollution Prevention Plan (P2 Plan). Which activity should be documented in this plan? → Procedures for managing outdoor storage of oil-bearing appliances to prevent runoff
9. Which of the following correctly describes the hierarchy of hazard controls, from most to least effective? → Elimination → Substitution → Engineering controls → Administrative controls → PPE
10. What is the minimum dielectric rating required for electrical insulating gloves used when working near energized 480V circuits? → Class 0 (1,000V rated)
11. What is 'freon banking' as it relates to legacy appliance refrigerants? → Storing collected refrigerants for future resale or reuse
12. A blueprint note reads 'TYP.' next to a dimension. This abbreviation means the dimension: → Applies to all similar features throughout the drawing
13. Which instrument is used to measure insulation resistance in a motor winding to detect breakdown? → Megohmmeter (Megger)
14. Which plastic resin code is commonly found on polypropylene washing machine tubs? → #5 (PP)
15. What is the recommended practice when an angle grinder wheel becomes cracked during appliance dismantling operations? → Remove and replace the wheel immediately
16. What is the required minimum clearance between a freestanding range and adjacent combustible cabinetry on each side? → 0 inches — modern ranges are designed flush to cabinetry
17. An appliance recycler discovers that a dishwasher contains a pump with suspected asbestos-containing insulation. The correct response is to: → Halt processing, isolate the unit, and consult asbestos abatement protocols
18. A window air conditioner blows warm air even though the compressor is running. The most likely cause is: → Low refrigerant charge due to a leak
19. Which federal regulation governs the proper handling and disposal of refrigerants recovered from household appliances? → EPA Section 608 of the Clean Air Act
20. A refrigerator being removed for recycling has a water line connected to its ice maker. What is the proper procedure? → Shut off the water supply valve and disconnect the line before moving the unit
21. Acrylonitrile butadiene styrene (ABS) plastic in appliance housings is best identified by which characteristic? → It sinks in water and has resin code #7 or #9
22. Which approach best supports quality outcomes in Blueprint Reading & Interpretation for Certified Appliance Recycler? → Systematic application of evidence-based methods
23. Under which section of RCRA are PCB-containing capacitors found in old appliances regulated as hazardous waste? → RCRA Subtitle C via TSCA cross-reference
24. A refrigerator is delivered that still contains food residue and mold. Before QC inspection proceeds, what should happen? → Clean the unit in a designated wash area with proper PPE
25. A recycler receives a chest freezer containing an unknown white crystalline substance inside the food compartment. The first action should be to: → Isolate the unit and report to the site supervisor
26. When testing a refrigerator start relay, a rattling sound when shaken indicates what? → The internal contact is broken and the relay has failed
27. Which label symbol on a chemical container indicates an acute health hazard such as toxicity? → Skull and crossbones
28. When handling refrigerants during appliance recycling, which type of glove material is MOST resistant to chemical permeation? → Nitrile gloves
29. When interpreting a heat pump blueprint, the reversing valve is identified because it: → Has four refrigerant line connections shown on the diagram
30. Foam insulation in older refrigerators may contain blowing agents such as CFC-11. During recycling, this foam should be: → Processed through a foam-shredding system with gas capture to recover the blowing agent
