Blog_ Understanding USP _800_ and how it relates to your refrigerator

When it comes to determining what refrigerators are safe and effective for use in your hazardous drug clean room, it is important to follow the guidelines set forth by the United States Pharmacopeia (USP). This infographic highlights the most important information relating to your USP <800> refrigerator.

As stated in USP General Chapter <800>, refrigerated antineoplastic hazardous drugs (HDs) must be stored in a dedicated refrigerator in a negative pressure area with at least 12 air changes per hour (ACPH).

Ensure that the refrigerator storing your antineoplastic HDs provides optimal temperature uniformity, stability and recovery. This keeps your valuable pharmaceuticals stored at precise temperatures to ensure efficacy and safety. Pharmaceutical-grade refrigerators will have a uniformity spec of +/-1 degree C.

Do not use a refrigerator pass-thru in your HD clean room.  This is specific to negative pressure rooms. Other methods of containment should be used for transferring product in and out of the HD clean room. Positive pressure clean rooms may continue using pass-thru refrigerators to enhance clean room workflows and reduce foot traffic in and out of the clean room, therefore, reducing contamination risk.
