Recycling Processes & Dismantling Procedures Flashcards

A recycler is processing a flood-damaged vehicle. Which additional hazard is MOST likely compared to a non-flood vehicle?

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.

Under EPA's Used Oil Management Standards (40 CFR Part 279), used oil collected at an automotive recycler must NOT be mixed with:

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.

What is the recommended torque sequence when reinstalling a cylinder head on a rebuilt engine destined for resale?

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.

Which of the following is a key indicator that a used transmission has suffered internal clutch pack failure during inspection?

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.

In the context of automotive recycling, what does 'parts interchangeability' data primarily help recyclers accomplish?

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.

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?

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.

What is the purpose of the 'National Motor Vehicle Title Information System' (NMVTIS) in automotive recycling?

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.
