Safety Training and Hazard Information

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.
1. Safety Training:
What to do? How to do this?
Obtain General Laboratory Safety Training, which includes orientation to and training on the Chemical Hygiene Plan Take the following training.

  • 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

Obtain Laboratory-specific training
  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

Maintain Training Records
  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.

2. Hazard Information: The following hazard information is available for PIs/Laboratory Supervisors and Laboratory Personnel to consult during the experiment planning process to assess the hazards and potential risks associated with the chemicals and laboratory operations:
For Information on: See:
Reference materials on the hazards, signs & symptoms of exposure, safe handling, storage & disposal of hazardous chemicals at the various website links:
Cal/OSHA’s Permissible Exposure Limits

“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.

Cal/OSHA’s Laboratory Standard

“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

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.


B. For Work Conducted Autonomously or Independently:
What to do? How to do this?
Consult with PI/Laboratory Supervisor
  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.
