EPA 608 Universal Practice Questions
and Answers | Latest Version | 2024/2025
| Graded A+
What is the main responsibility of a technician with an EPA 608 Universal certification?


✔✔ The primary responsibility is to handle refrigerants in a manner that prevents environmental

harm, including proper recovery, recycling, and disposal, while adhering to EPA regulations.




How do recovery cylinders differ from disposable cylinders in terms of refrigerant storage?


✔✔ Recovery cylinders are reusable, equipped with safety features like pressure relief valves,

and are color-coded for easy identification, whereas disposable cylinders are designed for single

use and cannot be refilled.




Why is it essential to remove non-condensable gases from a refrigeration system during service?


✔✔ Non-condensable gases, such as air, reduce system efficiency by increasing pressure and

temperature within the system, leading to potential damage and reduced cooling capacity.




What are the key factors that affect the speed of refrigerant recovery during system maintenance?


✔✔ Factors include the size of the system, the amount of refrigerant, ambient temperature, and

the efficiency of the recovery equipment being used.

, Why is it important to use the proper type of oil in refrigeration systems when working with

different refrigerants?


✔✔ Different refrigerants require specific oils for lubrication and system compatibility; using the

wrong type of oil can lead to system failure or reduced performance.




What is the significance of the EPA’s “de minimis” release rule in refrigerant handling?


✔✔ The "de minimis" release rule allows for small, unavoidable refrigerant emissions during

servicing or repair as long as the technician is following proper recovery procedures and using

certified equipment.




Why must technicians always check for and repair refrigerant leaks in a system before charging

it?


✔✔ Leaks must be repaired to prevent refrigerant loss, which not only reduces system efficiency

but also contributes to environmental harm through the release of ozone-depleting or high global

warming potential gases.




What are the penalties for knowingly venting refrigerants into the atmosphere during service or

repair?
