The Occupational Safety and Health Administration (OSHA) has developed numerous workplace regulations designed to prevent injuries and protect the health of workers. Laboratories are unique workplaces and in order to address the worker protection needs of these facilities OSHA developed a standard, Occupational Exposure to Hazardous Chemicals in Laboratories (29 CFR 1910.1450).
This standard, often referred to as the OSHA Laboratory Standard, imposes many requirements, including developing a written Chemical Hygiene Plan. The complete Chemical Hygiene Plan (CHP) for all university laboratories consists of three parts: The UW–Madison Campus Chemical Hygiene Plan and Compliance Guide, a laboratory-specific CHP, and the UW–Madison Chemical Safety Guide. These are described on this webpage.
