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.
