Dear BNC Cleanroom Users, On Wednesday February 26, 2020 starting at 7:30AM Purdue Physical Facility Department needs to shut down the medium pressure steam to the cleanroom humidification units for about 8 hours to make needed steam piping modification. If the outside weather is below normal conditions the cleanroom relative humidity levels can drop to 10% to 15% (normal humidity level is 45%), which will substantially increase electrostatic discharge when handling electronics devices in the cleanroom. Please contact me if you have any questions, and thank you for your patience during this interruption. Best Regards, Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036 [Purdue_University-150_Years_of_Giant_Leaps] www.purdue.edu/giantleaps<http://www.purdue.edu/giantleaps>
