Under RCRA, used oil drained from appliance compressors is classified as:
Answer: Used oil subject to the Used Oil Management Standards (40 CFR Part 279), not automatically classified as hazardous waste
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.
When an appliance recycling employee experiences symptoms of dizziness, headache, and nausea while working near refrigeration equipment, these are likely signs of:
Answer: Oxygen displacement or refrigerant overexposure in a confined or poorly ventilated space
Refrigerant vapors can displace oxygen and cause asphyxia symptoms including dizziness, headache, and nausea; the worker must be moved to fresh air immediately.
Which best practice prevents 'refrigerant cross-contamination' during recovery operations at an appliance recycling facility?
Answer: Dedicating separate, clearly labeled recovery cylinders to each refrigerant type
Dedicated and clearly labeled cylinders for each refrigerant type prevent cross-contamination, which can render recovered refrigerant unreclaimable and create disposal cost liabilities.
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?
Answer: Asbestos-containing materials in door gaskets and back panels
Appliances manufactured before 1980 may contain asbestos in door gaskets, back insulation panels, and other components, requiring testing or presumption before disturbance.
The Lockout/Tagout (LOTO) procedure applies in an appliance recycling setting primarily when:
Answer: Technicians perform maintenance on processing equipment such as shredders, conveyors, or balers
LOTO (29 CFR 1910.147) is required before any servicing or maintenance of machinery where unexpected energization or startup could injure workers.
Which universal waste rule allows appliance recyclers to manage certain hazardous wastes (such as fluorescent lamps and batteries) under a simplified set of requirements?
Answer: 40 CFR Part 273 Universal Waste Rule
The Universal Waste Rule (40 CFR Part 273) provides streamlined management standards for common hazardous wastes like batteries, fluorescent lamps, and mercury-containing equipment.
After a refrigerant spill in an enclosed processing area, air monitoring should confirm the concentration is below which threshold before workers re-enter without supplied-air respirators?
Answer: The Permissible Exposure Limit (PEL) or applicable occupational exposure limit for the specific refrigerant
Workers may re-enter without supplied-air respirators once air monitoring confirms concentrations are below the OSHA PEL or applicable occupational exposure limit for that specific refrigerant.
