After Hours

After hours is anytime outside of normal business hours including weekends and holidays. Those granted after-hours access must have an authorized buddy when using any hazardous materials or performing any work deemed hazardous in laboratory spaces. The buddy must be authorized to be on-site by SIF staff. Those who bring unauthorized individuals on-site may be barred from further SIF access.

Key Card Access

The doors of the building and the sample preparation laboratories will be locked at all times. All new users will be met at the front by SIF staff. The front door may not be propped open. Key card access for regular hours will be granted based on the completion of full instrument training. Each user will need to swipe when entering the building; holding the door open for multiple users is discouraged. Those granted after hours access will be given key card access to the building after normal business hours. Users will be granted after hours access on a case-by-case basis.


All users will need to be fully trained on each piece of equipment prior to independent use. Training cost includes instrument time plus the cost of labor.
