KNI Cleanroom Lab Rules and Safety Documents

All KNI members must follow the general SOPs, tool reservation policies, and cleanroom procedures.

To protect the safety of all lab users and staff, repeated violations to these policies will result in revocation of lab access.
This is an example of what could happen with a minor offense.
  • 1st offense will be a verbal warning.
  • 2nd offense will be an e-mail warning with the PI or supervisor copied in the e-mail.
  • 3rd offense will be a revocation of lab access until the offense is discussed with the PI or Supervisor.

Caltech's Laboratory Safety Orientation through the Environmental Health and Safety (EHS) department is required if you are using a lab on campus. The training is offered via Zoom twice a month. If you have not taken EHS Lab Safety Orientation, instructions to register for this training can be found at:
