Before choosing a recovery requirement, identify the appliance, the activity, the recovery equipment’s manufacture date, and the compressor’s condition. These eight original questions emphasize those distinctions, with related disposal and safety applications.
EPA lists three Type I groups: Recovery Requirements, Recovery Techniques, and Safety. This is independent educational practice, not an official exam or a complete simulation. Choose an answer before reading its explanation. EPA’s public test topics (opens in a new tab).
1. Recovery Requirements - The complete small-appliance definition
Which appliance meets the current federal definition of a small appliance?
Read answer and explanation
Answer: B. All the factory conditions and the charge limit must be satisfied. The definition expressly includes research refrigeration equipment; home use is not required. A fails the factory conditions, while C exceeds the five-pound limit. 40 CFR 82.152 (opens in a new tab).
2. Recovery Requirements - Older recovery equipment
Before opening a CFC-12 small appliance with a working compressor, a technician uses compliant recovery equipment manufactured in 1992. Which percentage requirement applies?
Read answer and explanation
Answer: A. Equipment manufactured before November 15, 1993, follows the 80% route regardless of compressor condition. The appliance’s date does not control. Four inches of mercury vacuum is a separate alternative. 40 CFR 82.156(b) (opens in a new tab).
3. Recovery Requirements - Working versus failed compressors
Compliant recovery equipment manufactured in 2020 is used before opening two CFC-12 small appliances. One compressor works; the other has failed. Which percentage pair applies, working/failed?
Read answer and explanation
Answer: C. For equipment manufactured on or after November 15, 1993, compressor condition determines which percentage applies. Four inches of mercury vacuum remains an alternative; the percentages are not the only compliance route. 40 CFR 82.156(b) (opens in a new tab).
4. Recovery Requirements - Equipment certification versus job results
A properly certified recovery machine was manufactured in 2020. What does its equipment-certification label establish?
Read answer and explanation
Answer: A. Equipment certification concerns capability under specified test conditions. A label does not document the result of an individual recovery job. The equipment standards and actual appliance-recovery obligations appear in separate provisions. 40 CFR 82.158(e), (h) (opens in a new tab); 40 CFR 82.156(b) (opens in a new tab). Technician certification is a separate qualification; owning the machine does not confer it. 40 CFR 82.161(a) (opens in a new tab).
5. Recovery Requirements - Service and waste-stream disposal
Two workers independently remove CFC-12 refrigerant from qualifying small appliances. One repairs a unit for continued use; the other recovers refrigerant solely for disposal from a unit in the waste stream. Neither is a supervised apprentice. Who needs Section 608 technician certification?
Read answer and explanation
Answer: C. The small-appliance disposal exception does not extend to maintenance, service, or repair for continued use. The activity changes the certification obligation. 40 CFR 82.161(a)(1) (opens in a new tab). The disposal worker still has refrigerant-recovery and recovery-equipment requirements; exemption from technician certification does not cancel those duties. 40 CFR 82.155(a) (opens in a new tab).
6. Recovery Requirements - Verification at final disposal
A scrap recycler taking the final disposal step receives discarded CFC-12 small appliances whose refrigerant was recovered upstream. It uses the signed-statement route. Which document supplies the required content?
Read answer and explanation
Answer: B. The statement must verify recovery of all refrigerant that had not previously leaked, as required by the rule. A qualifying signed supplier contract is another permitted route. The final processor must retain the statements or contracts on site for three years and cannot accept one it knows, or has reason to know, is false. An assurance or credential alone lacks the required verification. 40 CFR 82.155(b)–(c) (opens in a new tab).
7. Recovery Techniques - Understanding system-dependent equipment
A recovery-device description says refrigerant removal requires assistance from components inside the small appliance. Which classification fits?
Read answer and explanation
Answer: B. System-dependent equipment needs appliance components’ assistance; self-contained equipment can recover without it. 40 CFR 82.152 (opens in a new tab). EPA’s Type I outline includes passive recovery scenarios with both working and inoperative compressors. The classification alone does not establish a particular device’s suitability or explain its operation. EPA’s Recovery Techniques objectives (opens in a new tab).
8. Safety - High-temperature decomposition
Which statement correctly describes a hazard when CFC refrigerant undergoes high-temperature decomposition?
Read answer and explanation
Answer: A. Decomposition changes chemical composition. EPA’s technical report identifies dangerous halogen acids among CFC destruction products. A simple phase change does not describe that chemical hazard, and carbon compounds are not the only possible products. This explanation concerns CFC chemistry; it does not establish identical decomposition products for every refrigerant. EPA’s Technologies for CFC/Halon Destruction, section 2 (opens in a new tab).
For each missed question, write down the fact that changes the answer and explain why the closest alternative fails. Revisit the corresponding group in the official EPA outline (opens in a new tab), then schedule that topic in your study plan.
