EPA Section 608 Universal Certification ExamType II (High-Pressure Appliances)Easy
Which of the following statements is TRUE regarding the use of disposable cylinders for refrigerants recovered from high-pressure appliances?
- ADisposable cylinders are allowed for recovered refrigerants if the appliance charge is less than 5 lbs.
- BDisposable cylinders can be used for recovery if they are less than 50% full.
- CDisposable cylinders are only allowed for virgin (new) refrigerants and cannot be used for recovery.
- DDisposable cylinders are permitted for recovered refrigerants if they are clearly labeled.
Show answer & explanationAnswer & explanation
Correct answer: C. Disposable cylinders are only allowed for virgin (new) refrigerants and cannot be used for recovery.
EPA regulations strictly prohibit the use of disposable cylinders for recovering or storing any type of refrigerant. Disposable cylinders are designed for a single use with virgin refrigerant and do not have the robust construction or safety features required for recovered refrigerants, which may contain contaminants or be under varying pressures.
Why the other options are wrong
- A. The size of the appliance charge does not permit the use of disposable cylinders for recovery.
- B. The fill level does not change the fact that disposable cylinders are not approved for recovered refrigerants.
- D. Labeling does not override the fundamental prohibition against using disposable cylinders for recovery.
Disposable Cylinder Use
Disposable refrigerant cylinders are strictly for virgin (new) refrigerant only and are prohibited from being used for the recovery or storage of any type of recovered refrigerant.
- Only for virgin refrigerant.
- Cannot be used for recovery.
- Safety and regulatory requirement.
Memory trick: Disposable means 'done' after virgin use, never for reuse with recovered 'juice'.
