What is the minimum ACPH for a dedicated refrigerator storing refrigerated HDs?

• A. 6 ACPH
• B. 12 ACPH
• C. 18 ACPH
• D. 24 ACPH

Answer: (B)

Air changes per hour measure how often the air in a space is replaced in one hour, which helps dilute any hazardous-drug vapors that could escape when a door is opened. For a refrigerator dedicated to storing refrigerated hazardous drugs, the minimum standard is twelve air changes per hour. This level provides enough dilution to reduce potential staff exposure while keeping energy use reasonable. Lower values, like six, may not offer sufficient dilution, while higher values (eighteen or twenty-four) exceed the minimum and usually aren’t necessary for typical storage needs.
