Hazardous Chemicals in the Chemical Hygiene Plan

Research and teaching laboratories frequently work with a wide range of chemicals that present physical, health, and environmental hazards. This section of the Chemical Hygiene Plan serves as a central resource for understanding chemical hazard classes, recognizing incompatible materials, managing particularly hazardous substances (PHS) and EPA-regulated chemicals, communicating hazards effectively, responding to spills and accidents, and assessing potential exposures.

By understanding these concepts and applying appropriate controls, laboratory personnel can conduct research safely, protect themselves and others, and support the institution's commitment to regulatory compliance, environmental stewardship, and scientific excellence.
