Appropriate personal protective equipment (PPE) to be worn while handling hazardous medications is addressed in USP Chapter:

USP Chapter 795 focuses on the compounding of non-hazardous drugs, providing guidelines for ensuring quality and safety in the preparation of such medications. It does not address the specific requirements for handling hazardous medications or the associated PPE, making it irrelevant to this question.

USP Chapter 797 deals with the compounding of sterile preparations, emphasizing the need for aseptic techniques and environmental controls. While it is critical for ensuring the safety of sterile products, it does not specifically cover hazardous medications or the protective measures required when handling them.

USP Chapter 825 is related to the compounding of specialty sterile preparations, focusing on specific practices and requirements for certain types of compounded sterile drugs. Like Chapters 795 and 797, it does not pertain to hazardous medications or the necessary PPE for their handling.
