PI / Laboratory Supervisors must inform laboratory personnel of the location and availability of the following information:

A. Occupational Exposure to Hazardous Chemicals in Laboratories.” California Code of Regulations Title 8, Section 5191.

Cal/OSHA is a governmental agency that protects worker health and safety in the State of California. This regulation was promulgated to protect laboratory personnel engaged in the laboratory use of hazardous chemicals. [NOTE: Custodial and maintenance staff who service the laboratory fall under Cal/OSHA’s Hazard Communication Standard, Code of Regulations Title 8, Section 5194.]

B. Stanford University’s Chemical Hygiene Plan.

The above-referenced Cal/OSHA regulation requires employers to have a written Chemical Hygiene Plan. This Plan fulfills this regulatory requirement and is a resource for planning experiments and laboratory operations.

C. “Permissible Exposure Limits (PEL) for Chemical Contaminants”, California Code of Regulations, Title 8, Section 5155.

Cal/OSHA establishes regulatory exposure limits for many airborne contaminants; the actual values are in Table AC-1. If a PEL has not been established for a specific contaminant, contact EH&S for guidance.
