Pharmacy Clean Room

Provided a new clean room for the pharmacy group at the Veterans Administration (VA) Hospital in Wilmington, Delaware meeting the requirements of USP 797. Issued by U.S. Pharmacopoeia (USP), this regulation governs any pharmacy that prepares “compounded sterile preparations” (CSPs). The project consists of one ISO Class 8 anteroom adjacent to a positive pressure ISO Class 7 non-hazardous cleanroom that leads to a negative pressure ISO Class 7 hazardous cleanroom. The project also includes the construction of a temporary USP 797 non-compliant space for the pharmacy to use during construction of the new USP-797 compliant clean room.
