AARC Recycling Processes & Dismantling Procedures 5 — Questions and Answers
Question 1: A recycler is processing a flood-damaged vehicle. Which additional hazard is MOST likely compared to a non-flood vehicle?
- Higher risk of airbag non-deployment
- Elevated risk of mold, biohazardous contamination, and compromised electrical system safety (Correct answer)
- Increased catalytic converter precious metal content
- Stronger structural steel requiring heavier cutting equipment
Correct answer: Elevated risk of mold, biohazardous contamination, and compromised electrical system safety
Flood vehicles may contain mold, sewage contamination, and compromised wiring insulation, requiring additional PPE and decontamination procedures.
Question 2: Under EPA's Used Oil Management Standards (40 CFR Part 279), used oil collected at an automotive recycler must NOT be mixed with:
- Different viscosity grades of used motor oil
- Used transmission fluid or used gear oil
- Used oil that has been filtered but not re-refined
- Hazardous waste solvents or listed hazardous wastes (Correct answer)
Correct answer: Hazardous waste solvents or listed hazardous wastes
Mixing used oil with listed hazardous wastes (e.g., halogenated solvents) reclassifies the mixture as hazardous waste, triggering far more stringent disposal requirements.
Question 3: What is the recommended torque sequence when reinstalling a cylinder head on a rebuilt engine destined for resale?
- Outside-in spiral pattern to center pressure evenly
- Inside-out pattern in multiple passes per manufacturer specifications (Correct answer)
- Random sequence as long as all bolts reach final torque
- Single-pass tightening from the front of the engine to the rear
Correct answer: Inside-out pattern in multiple passes per manufacturer specifications
Manufacturer-specified inside-out, multi-pass torque sequences ensure even gasket compression and prevent head warping.
Question 4: Which of the following is a key indicator that a used transmission has suffered internal clutch pack failure during inspection?
- Gear oil that is slightly darker than new fluid
- Presence of metallic particles or burnt smell in the transmission fluid (Correct answer)
- An oil level slightly above the full mark
- Minor surface rust on the exterior case
Correct answer: Presence of metallic particles or burnt smell in the transmission fluid
Metallic particles indicate friction material or gear wear, and a burnt smell signals overheated clutch packs, both indicating internal failure.
Question 5: In the context of automotive recycling, what does 'parts interchangeability' data primarily help recyclers accomplish?
- Determine the scrap metal value of a part by weight
- Identify which parts from different year/make/model vehicles are functionally compatible for cross-selling (Correct answer)
- Calculate the labor time required to remove a specific part
- Verify that a part meets current EPA emission standards
Correct answer: Identify which parts from different year/make/model vehicles are functionally compatible for cross-selling
Interchangeability data (from sources like Hollander) allows recyclers to match a buyer's vehicle need with compatible parts from different model years, expanding saleable inventory.
Question 6: A facility receives a vehicle with an active recall for a defective Takata airbag inflator. What must the recycler do before selling the airbag module?
- Sell the module with a disclosure sticker noting the recall
- The recycler must NOT sell the recalled inflator/module; it must be rendered inoperable or returned for destruction (Correct answer)
- Test-fire the module to confirm it functions and then sell if it deploys
- Contact the vehicle manufacturer for a replacement module to sell instead
Correct answer: The recycler must NOT sell the recalled inflator/module; it must be rendered inoperable or returned for destruction
Selling a recalled safety-critical part like a Takata inflator is prohibited; it must be destroyed or returned to the manufacturer's recall program to prevent harm.
Question 7: What is the purpose of the 'National Motor Vehicle Title Information System' (NMVTIS) in automotive recycling?
- It provides real-time scrap metal pricing for recycled vehicles
- It is a federal database that recyclers must report to, helping prevent title fraud and tracking vehicle history including salvage designations (Correct answer)
- It certifies that a vehicle has passed emissions testing before recycling
- It manages the licensing of automotive recycling facilities at the federal level
Correct answer: It is a federal database that recyclers must report to, helping prevent title fraud and tracking vehicle history including salvage designations
NMVTIS requires junk and salvage yards to report acquired vehicles within specific timeframes, creating a national database that combats title washing and fraud.
