CAR Appliance Recycler Safety & Hazardous Material Handling 5

Question 1

Under RCRA, used oil drained from appliance compressors is classified as:

Accepted Answer

Used oil subject to the Used Oil Management Standards (40 CFR Part 279), not automatically classified as hazardous waste

Answer

Compressor oil is managed under EPA's Used Oil Management Standards (40 CFR Part 279) unless it has been mixed with a listed hazardous waste or exhibits hazardous characteristics.

Question 2

When an appliance recycling employee experiences symptoms of dizziness, headache, and nausea while working near refrigeration equipment, these are likely signs of:

Accepted Answer

Oxygen displacement or refrigerant overexposure in a confined or poorly ventilated space

Answer

Refrigerant vapors can displace oxygen and cause asphyxia symptoms including dizziness, headache, and nausea; the worker must be moved to fresh air immediately.

Question 3

Which best practice prevents 'refrigerant cross-contamination' during recovery operations at an appliance recycling facility?

Accepted Answer

Dedicating separate, clearly labeled recovery cylinders to each refrigerant type

Answer

Dedicated and clearly labeled cylinders for each refrigerant type prevent cross-contamination, which can render recovered refrigerant unreclaimable and create disposal cost liabilities.

Question 4

A CAR-certified recycler is processing a batch of refrigerators manufactured before 1980. They should specifically test or presume the presence of which hazardous insulation material?

Accepted Answer

Asbestos-containing materials in door gaskets and back panels

Answer

Appliances manufactured before 1980 may contain asbestos in door gaskets, back insulation panels, and other components, requiring testing or presumption before disturbance.

Question 5

The Lockout/Tagout (LOTO) procedure applies in an appliance recycling setting primarily when:

Accepted Answer

Technicians perform maintenance on processing equipment such as shredders, conveyors, or balers

Answer

LOTO (29 CFR 1910.147) is required before any servicing or maintenance of machinery where unexpected energization or startup could injure workers.
