The United States Pharmacopeia (USP) General Chapter 800 addresses the handling of hazardous drugs (HDs) to minimize the risk of exposure to patients, health care workers and the environment. It became compendially applicable in November 2023. USP 800 contains some key elements that specifically apply to employee safety and HD containment. Section 16, for example, discusses managing HD spills and retaining spill kits on site. This article addresses HD spills that occur in a compounding pharmacy; however, it can be adapted for handling of non-HD chemical spills as well.
