What records should be kept for R-22?

• A. Type of refrigerant, dates and quantity of refrigerant
• B. Dates only
• C. Type only
• D. Quantity only

Answer: (A)

Recordkeeping for R-22 focuses on documenting what refrigerant is used and what happens to it. You should keep three pieces of information: the type of refrigerant, the dates of service or purchases, and the quantity of refrigerant recovered or charged. Having all three creates a complete, traceable record that supports regulatory compliance and future maintenance.

If only dates were kept, you wouldn’t know which refrigerant was involved or how much was used. If only the type were kept, you’d miss when and how much was charged or recovered. If only the quantity were kept, you wouldn’t know the refrigerant identity or the timing of the action. Keeping the type, dates, and quantity together gives a full, useful record.
