Complying with USP <797> Requirements for Cleanrooms and Other Controlled Environments

This Handbook contains ISO Standards and IEST Recommended Practices to assist clinical and pharmaceutical personnel as well as cleanroom design and operations professionals in implementing controlled environments that comply with the requirements of USP Chapter 797 “Pharmaceutical Compounding – Sterile Preparations” (USP <797>).

Available in the IEST Bookstore

USP 797 requires compounding pharmacies to determine the risk level of the compounding done in their facilities and to perform the compounding in cleanrooms or other controlled environments as specified for the risk level. The documents in this Handbook will help users:
• Determine, design, and maintain the proper controlled environment for your application.
• Develop standard procedures for cleaning the controlled environment.
• Implement environmental sampling to monitor air quality regularly for viable and nonviable particles.
• Develop standard procedures for personnel gowning and gloving.
