Introduction
The EPA 608 Core Certification Exam is a mandatory assessment designed to ensure that
,technicians working with stationary refrigeration and air conditioning systems possess a
fundamental understanding of environmental protection and safety protocols. This exam
evaluates knowledge regarding the depletion of the stratospheric ozone layer, the global
warming impact of various refrigerants, and strict adherence to the Clean Air Act. Through a
series of multiple-choice and scenario-based questions, candidates must demonstrate
proficiency in regulatory compliance, equipment maintenance, and hazardous material
handling. This practice test focuses on practical application and professional decision-making
to ensure a high standard of environmental stewardship in the field.
1. Which of the following gases is primarily responsible for the depletion of the stratospheric
ozone layer?
A. Carbon Dioxide
🔴 B. Chlorine
C. Helium
D. Hydrogen
🔵 Explanation: Chlorine atoms released from CFCs and HCFCs react with ozone
molecules, breaking them apart and thinning the ozone layer.
2. What is the Global Warming Potential (GWP) of R-744 (Carbon Dioxide)?
🔴 A. 1
B. 10
C. 100
, D. 1,000
🔵 Explanation: Carbon Dioxide is used as the baseline for GWP, giving it a value of 1.
3. Under Section 608 of the Clean Air Act, it is illegal to:
A. Repair a small appliance.
B. Use recycled refrigerant.
🔴 C. Knowingly vent refrigerants during service or disposal.
D. Sell a recovery machine to a certified technician.
🔵 Explanation: The "venting prohibition" strictly forbids the intentional release of ODS
and substitute refrigerants while maintaining or disposing of equipment.
4. Which type of refrigerant has the highest Ozone Depletion Potential (ODP)?
🔴 A. CFCs
B. HCFCs
C. HFCs
D. HFOs
🔵 Explanation: Chlorofluorocarbons (CFCs) contain chlorine and are highly stable,
allowing them to reach the stratosphere intact and cause maximum damage.
5. What is the definition of "Recycle" as it pertains to Section 608?
A. To clean refrigerant to a level equal to new product specifications.
🔴 B. To extract refrigerant and clean it for reuse without meeting all virgin specifications.
C. To vent the refrigerant safely into a water bath.
, D. To change the chemical composition of the refrigerant.
🔵 Explanation: Recycling involves cleaning refrigerant for reuse by oil separation and
single or multiple passes through moisture-absorption devices.
6. Which international treaty regulated the production and use of CFCs and HCFCs?
A. The Kyoto Protocol
🔴 B. The Montreal Protocol
C. The Paris Agreement
D. The Geneva Convention
🔵 Explanation: The Montreal Protocol is the global agreement specifically designed to
phase out the production of ozone-depleting substances.
7. A violation of the Clean Air Act, such as falsifying records, can result in a fine of up to
approximately how much per day, per violation?
A. $5,000
B. $15,000
🔴 C. $44,539
D. $100,000
🔵 Explanation: The EPA adjusts civil penalties for inflation; currently, the fine exceeds
$44,000 per day per violation.
8. When must a recovery device be certified by an EPA-approved laboratory?
A. Only if it is used for HFCs.
