Thank you, From: Bnc-facility-notice <bnc-facility-notice-bounces@ecn.purdue.edu<mailto:bnc-facility-notice-bounces@ecn.purdue.edu>> On Behalf Of Voorhis, Mark L.

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.
