This Web-based Chemical Hygiene Plan and Laboratory Safety Manual must be readily available to personnel at YSU.


YSU's Chemical Hygiene Plan (CHP) provides for and supports procedures, equipment, personal protective equipment, and work practices to protect personnel from the potential health and physical hazards of laboratory work with hazardous chemicals, and complies with Occupational Safety and Health Administration (OSHA) Occupational Exposure to Hazardous Chemicals in Laboratories.

What is Chemical Hygiene?

Hygiene implies conditions or practices conducive to maintaining health and preventing disease. Thus “Chemical Hygiene” relates to maintaining health and preventing disease by setting up and operating the laboratory environment to minimize exposure to harmful chemicals.
