CAR Vehicle Dismantling & Processing 3 â Questions and Answers
Question 1: When removing a catalytic converter for recycling, which measurement is MOST important for determining its precious metal value?
- The converter's external dimensions
- The substrate type and precious metal content (Correct answer)
- The vehicle's original MSRP
- The converter's weight in pounds
Correct answer: The substrate type and precious metal content
The substrate material and its platinum group metal (PGM) contentâplatinum, palladium, and rhodiumâdirectly determine a catalytic converter's scrap value.
Question 2: Which type of transmission fluid requires separate collection from engine oil during vehicle depollution?
- Only automatic transmission fluid (ATF)
- All transmission fluids including manual and CVT fluids (Correct answer)
- Only CVT fluid due to its synthetic composition
- Transmission fluid can be mixed with engine oil for disposal
Correct answer: All transmission fluids including manual and CVT fluids
All transmission fluidsâATF, manual transmission fluid, and CVT fluidâmust be collected separately as they have different chemical compositions and recycling pathways.
Question 3: A 2019 diesel vehicle arrives for processing. Which additional fluid NOT present in gasoline vehicles must be drained?
- Power steering fluid
- Diesel Exhaust Fluid (DEF) (Correct answer)
- Brake fluid
- Windshield washer fluid
Correct answer: Diesel Exhaust Fluid (DEF)
Diesel Exhaust Fluid (DEF), used in SCR emissions systems, is specific to modern diesel vehicles and must be separately drained and managed.
Question 4: What does the term 'yield' refer to in automotive shredder operations?
- The number of vehicles processed per hour
- The percentage of ferrous metal recovered from shredded material (Correct answer)
- The total weight of a vehicle before shredding
- The energy consumed per ton of material shredded
Correct answer: The percentage of ferrous metal recovered from shredded material
Yield in shredder operations refers to the percentage by weight of ferrous steel recovered from the total shredded material, a key efficiency metric.
Question 5: Under the ARA's Certified Automotive Recycler program, what is the required frequency for employee training on hazardous material handling?
- Once at initial hire only
- Annually, with documentation maintained on file (Correct answer)
- Every five years per federal mandate
- Only when regulations change
Correct answer: Annually, with documentation maintained on file
The CAR program requires annual documented training on hazardous material handling to ensure ongoing compliance and worker safety.
Question 6: Which component of an end-of-life vehicle is classified as a Universal Waste under EPA regulations?
- Engine oil
- Lead-acid batteries (Correct answer)
- Brake fluid
- Transmission fluid
Correct answer: Lead-acid batteries
Lead-acid batteries are classified as Universal Waste under 40 CFR Part 273, allowing simplified management compared to hazardous waste regulations.
Question 7: When a late-model vehicle with an integrated body structure (unibody) is dismantled, what specialized tool is typically required to separate structural sections?
- Standard flathead screwdriver
- Plasma cutter or reciprocating saw with metal blades (Correct answer)
- Hand-operated hydraulic floor jack
- Standard socket wrench set
Correct answer: Plasma cutter or reciprocating saw with metal blades
Plasma cutters or reciprocating saws with metal-cutting blades are needed to section unibody vehicles since they lack bolt-on frame components found in body-on-frame designs.
