Mixed Deck — All AARC Topics Flashcards

What is the primary reason high-voltage EV battery packs must be stored separately from other vehicle fluids at a recycling facility?

Answer: To prevent thermal runaway ignition near flammable materials

Thermal runaway in damaged lithium-ion cells can ignite nearby flammable fluids, so segregated storage is required for fire safety.

When a vehicle delivered to an auto recycler still contains airbag inflators with sodium azide propellant, these inflators are regulated as:

Answer: Hazardous waste under 40 CFR Part 261

Unexploded airbag inflators containing sodium azide are classified as reactive hazardous waste (D003) under RCRA if disposed, not recycled.

Which of the following best describes the 'conditionally exempt small quantity generator' (CESQG) threshold under current RCRA regulations (post-2016 revisions)?

Answer: Generates less than 100 kg per month and is now referred to as Very Small Quantity Generator (VSQG)

The 2016 RCRA Generator Improvements Rule renamed CESQG to Very Small Quantity Generator (VSQG), maintaining the 100 kg/month threshold with specific management options.

Which part category typically requires the most detailed interchange data in an inventory listing to avoid incorrect fitment sales?

Answer: Engine control modules (ECM)

ECMs are highly vehicle-specific and may require VIN-level programming, so detailed interchange and calibration data are essential.

Which metric helps evaluate inventory turnover?

Answer: Turnover ratio

The inventory turnover ratio is a key metric that helps evaluate how quickly inventory is sold and replaced over a specific period. A higher turnover ratio generally indicates efficient inventory management and strong sales. This metric is vital for optimizing stock levels, minimizing holding costs, and maximizing profitability in auto recycling operations.

A recycling business wants to improve its operational efficiency and profitability. According to best business practices in the industry, which area should management focus on first to have the most significant impact?

Answer: Implementing a system to accurately track inventory, evaluate the profitability of different vehicle sources, and price parts competitively.

Effective business operations in auto recycling heavily depend on managing the core functions of purchasing and inventory. Establishing systems to evaluate vehicle sources for ROI, track parts accurately, and use market data for pricing directly impacts the bottom line. While marketing and facility appearance are important, they are secondary to the core profit-generating activities of inventory management.

What is the purpose of a 'vehicle depollution' step in the ARC-certified recycling process?

Answer: To systematically remove all hazardous fluids and materials before dismantling or shredding

Depollution is the systematic removal of all hazardous materials—fluids, batteries, airbags, mercury switches—before the vehicle enters the dismantling or shredding stream.

Which of the following represents a best management practice for storing used tires at an automotive recycling facility to minimize environmental and safety risks?

Answer: Storing them indoors or under a cover to prevent water accumulation.

Storing tires indoors or under a cover is a key EPA best management practice to prevent them from collecting rainwater. Standing water in tires creates a prime breeding ground for mosquitoes, which can carry diseases. This practice also helps minimize fire risk and keeps the storage area more manageable.

Under ARA's Code of Ethics, how must an AARC-certified recycler handle a customer complaint about a defective part?

Answer: Resolve it promptly and fairly in good faith

ARA's Code of Ethics requires AARC members to resolve customer disputes promptly and in good faith as a fundamental ethical obligation.

How should damaged parts be labeled?

Answer: Clearly marked and noted

Damaged parts must be clearly marked and their condition noted in the inventory system to prevent misrepresentation and ensure customer satisfaction. This transparency helps buyers make informed decisions and prevents the accidental sale of unusable parts. Proper labeling also aids in efficient inventory management and quality control, maintaining trust with customers.

An AARC-compliant facility must conduct employee safety training:

Answer: Annually at minimum, with documented records

Best practices and most regulatory frameworks require documented annual safety training to ensure employees remain current on hazards and procedures.

To minimize the risk of musculoskeletal injuries among vehicle dismantlers, which of the following is a key ergonomic best practice for a facility to implement?

Answer: Providing adjustable-height vehicle lifts or work platforms.

Adjustable-height lifts allow technicians to position the vehicle at a comfortable working height, minimizing the need for bending, reaching, and working in awkward postures. This directly reduces physical strain and is a primary engineering control for preventing musculoskeletal disorders (MSDs).

In an automotive recycling facility, 'secondary containment' around fluid storage tanks is required to hold at minimum:

Answer: 110% of the largest single tank's capacity

EPA Spill Prevention, Control, and Countermeasure (SPCC) rules require secondary containment of at least 110% of the largest tank to contain a full spill plus precipitation.

Which inventory turnover strategy involves reducing prices on slow-moving parts to free up capital and space?

Answer: Markdown or liquidation pricing

Markdown or liquidation pricing deliberately lowers prices on aged or slow-moving inventory to convert dead stock back into working capital.

Catalytic converters removed from vehicles at an auto recycler may contain which hazardous substance that requires careful handling?

Answer: Chromium-6 in the substrate coating

Some catalytic converter substrates and coatings can contain hexavalent chromium (Cr-6), a known carcinogen that requires appropriate PPE and disposal precautions.

Which of the following best describes 'commingling' in the context of automotive recycling financial records?

Answer: Mixing personal funds with business funds in the same account

Commingling refers to mixing personal and business funds, a practice that violates accounting ethics and can create legal liability.

When storing gasoline drained from vehicles in a portable container, which of the following is a key OSHA and fire code requirement?

Answer: The container must be a UL-approved or FM-approved safety can with a flame arrester.

OSHA regulation 29 CFR 1910.106 requires that flammable liquids like gasoline be stored in approved containers. A safety can, which is listed or approved by a nationally recognized testing laboratory like UL or FM, is designed with features such as a spring-closing lid and a flame arrester to prevent ignition and safely vent pressure under fire conditions.

Which action is PROHIBITED when managing airbag inflator modules at an automotive recycling facility?

Answer: Disposing of deployed modules as regular solid waste

Deployed airbag inflators may contain residual sodium azide or other hazardous propellants and must be disposed of as hazardous waste, not regular trash.

Which automotive fluid is regulated as a 'listed hazardous waste' (F-list) if it is used as a solvent for degreasing parts?

Answer: Spent chlorinated solvents such as TCE or perchloroethylene

Spent chlorinated solvents used for degreasing appear on the EPA F-list (F001–F005) and are classified as listed hazardous waste regardless of contamination levels.

Why is staff training important?

Answer: Understand safe and ethical practices

Staff training is vital to ensure employees understand and implement safe and ethical practices in all aspects of auto recycling. This includes proper handling of hazardous materials, safe operation of equipment, and adherence to environmental regulations, protecting both workers and the environment.
