Answer 1

Neither Technician A nor Technician B is correct regarding the usage of disposable tanks for recycled refrigerant, but Technician B is correct about filling refrigerant tanks to 70% of their gross weight rating.

Step-by-step explanation:

The student's question concerns whether it is acceptable to use a disposable refrigerant tank to store recycled refrigerant, and the propriety of filling an approved refrigerant tank to 70% of its gross weight rating. In regards to Technician A's claim, it is not advisable or commonly accepted practice to use disposable refrigerant tanks to store recycled refrigerant as they are not designed for multiple uses and could have liability or safety implications. Technician B is correct, as it is standard practice to fill refrigerant tanks to 70% of their gross weight rating to allow for safe expansion of the refrigerant at varying temperatures. This practice avoids overpressurization and potential hazards.
