Safety resources
The USC Nanofab thanks you for your commitment to safety. By your situational awareness and attention to policy, our facility stays a safe place to work.
Administrative processes
Safety trainings
If you are an active user, you will have already completed both the General Lab Safety course with USC EHS as well as the Nanofab's Cleanroom safety training, as detailed in the New user onboarding procedure. This permits you cleanroom access and the ability to request tool trainings, which will have safety aspects built into the training content (e.g., Fumehood training). The training request form is linked from the wiki homepage and the NEMO homepage.
To maintain cleanroom access, all users must complete annual cleanroom-specific safety refresher training. This is sent out as an email invitation to all users with multiple sessions available.
Chemical approval
To get approval to bring in new chemicals into the cleanroom, submit a Chemical Approval Form, including the SDS, so that our staff and USC EHS are aware of it. When a chemical is completely used, alert staff to update the chemical inventory.

Safety Data Sheets (SDSs)
It's critical to know the hazards associated with the chemicals you handle. This can inform how you work with it, or whether you choose to use it at all. Additionally, regulating bodies require that SDSs are made available in the workplace. If you are handed an unfamiliar chemical, ask for the SDS.
SDSs for chemicals you can expect to find in the Nanofab
USC EHS has also pooled a list of SDS sources from chemical distributors.
