Which of the following statements about disposable refrigerant cylinders is TRUE?
- AThey must be returned to the manufacturer once empty.
- BThey can be refilled with the same type of refrigerant by certified technicians.
- CThey are color-coded grey with a yellow top for universal identification.
- DThey are typically used for transporting recovered refrigerant to reclaimers.
Show answer & explanationAnswer & explanation
Correct answer: A. They must be returned to the manufacturer once empty.
Disposable refrigerant cylinders are designed for one-time use and are typically used to package virgin refrigerant. Once empty, they must be returned to the manufacturer or supplier for proper disposal, not refilled or used for recovery.
Why the other options are wrong
- B. Disposable cylinders are strictly 'one-time use' and cannot be refilled, even by certified technicians.
- C. Disposable cylinders are typically light blue or green for virgin refrigerants, not grey with a yellow top (which is for recovery cylinders).
- D. Recovery cylinders (reusable) are used for transporting recovered refrigerant, not disposable cylinders.

Memory trick: Disposable: 'One-time Use, Then Return'!
