Summary: To apprise laboratory personnel of the hazards of chemicals present in their work area, information and training must be made available.

A. For Work Directed by PI/Laboratory Supervisor: Laboratory personnel must receive general and laboratory-specific information and training at the time of initial assignment to the laboratory, and prior to assignments involving new exposure situations, Particularly Hazardous Substances, and hazardous operations.

• General Safety & Emergency Preparedness (EHS-4200)*
• Chemical Safety for Laboratories (EHS-1900)*

AND, where applicable:

• Compressed Gas (EHS-2200)*
• Computer Workstation Ergonomics (EHS-3400)*
• Laboratory Ergonomics (call EH&S at 723-0448)

* For on-line classes, register in STARS at https://axess.stanford.edu/.

1. See your PI/Laboratory Supervisor to review the lab-specific training procedures for your lab.
2. Review any individual Laboratory Safety Plan.
3. Complete lab-specific training* or equivalent, which includes:
   • Local/building safety information.
   • Standard Operation Procedure(s) involving hazardous materials. You may use the form Documenting SOP & PI Approval to document your review.
   • Any other laboratory-specific safety procedures or hazards that may be encountered in the laboratory environment. Lab-owned equipment may require specialized training to ensure safety and prevent equipment damage.

   * Additional guidance for PIs on how to develop lab-specific training can be found in How to Develop Lab-Specific Training

1. PI/Laboratory Supervisor or designate must retain training documents for laboratory personnel at least one year.

2. Use How to Develop Lab-Specific Training or equivalent to document training.

• Material Safety Data Sheets
• Stanford University’s Chemical Safety Database
• Chemical Safety, National Institute for Occupational Safety & Health
• SOP Template, section #4

"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 is not established for a specific contaminant, contact EH&S for guidance.

"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.]

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 information used for planning experiments and laboratory operations.

1. PI/Laboratory Supervisor or designate must retain training documents for laboratory personnel at least one year. Note: Training records for EHS-provided trainings are maintained electronically.
2. Obtain any other training that is appropriate to the work you conduct in Stanford University laboratories.
   • Provide appropriate oversight, training and safety information to any laboratory personnel you supervise or direct.
