Which of the following records must be kept for R-22?

• A. Type of refrigerant, Dates, Quantity of refrigerant
• B. Date of purchase
• C. Supplier name
• D. Storage location

Answer: (A)

R-22 is a regulated refrigerant, so proper recordkeeping under EPA rules requires a clear purchase trail. The essential records include the type of refrigerant, the date of the transaction, and the quantity. This combination creates a complete and traceable log of what was bought, when, and in what amount, which supports compliant handling, inventory control, and potential inspections.

A date alone doesn’t identify the substance or how much was purchased, and while supplier name or storage location might be useful for internal processes, they aren’t the specific required fields for this purchase record.
