Re: [Bnc-facility-notice] NOTICE - Campus Steam Outage - Controlled Shutdown Cancelled
by Voorhis, Mark L. 19 Feb '20

19 Feb '20

Dear BNC User - 4:30 PM update - The steam pressure has shown a small increase from 3 PSI to 12 PSI and climbing. At this time we will cancel the controlled shutdown of the cleanroom and general labs air handling and chemical exhaust systems. All fume hoods, toxic gases, and chemical processes will remain operational. As part of the steam contingency plan the atrium and office areas will remain off until the steam pressure is back to normal. Once the steam pressure is back to normal it will take 12 hours for the cleanroom clean steam generators to heat up and stabilize. So cleanroom humidity will not be in control until mid-morning tomorrow. I will send another update when steam pressure is back to normal. Thank you for your patience during this campus wide unscheduled outage.

Re: [Bnc-facility-notice] NOTICE - Campus Steam Outage - CLEANROOM & GENERAL LAB SHUTDOWN!
by Voorhis, Mark L. 19 Feb '20

19 Feb '20

Dear BNC User - Update - There has been no change with the steam pressure at this time. Due to issues outside of our control at 4:30PM we will start to do a controlled shutdown of the cleanroom and general lab handling system and ALL chemical exhaust. This means that all fume hoods, toxic gases, and chemical process will need to be contained and shutdown! If the steam pressure starts to return prior to 4:30PM then we will send a update to cancel the controlled shutdown.

Sent: Wednesday, February 19, 2020 1:48 PM To: bnc-facility-notice(a)ecn.purdue.edu Subject: [Bnc-facility-notice] Campus Steam Outage Dear BNC Users - We have lost campus wide steam pressure at few minutes ago wade power plant steam boilers shut down. Several building alarms came in that we are responding to. Our high pressure steam normally operates at 125 psi and is currently at 13psi. We have lost humidity control for cleanroom and general lab spaces. We are close to losing HVAC controls for the general labs. We have implemented steam contingency plans and shut all atrium and office HVAC systems plus all general lab and cleanroom humidity control. The humidity in the general labs and cleanroom are very low at 20% (normal is 45%). Wade is in the process of bring up their boilers.

NOTICE - Interruption to Cleanroom Humidity Control
by Voorhis, Mark L. 10 Feb '20

10 Feb '20

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>

NOTICE - Loss of Campus Steam Pressure
by Voorhis, Mark L. 20 Jan '20

20 Jan '20

Dear BNC Users - We have lost campus wide steam pressure at 11:30AM where 2 of 4 wade power plant steam boilers shut down. Several building alarms came in that we are responding to. Our high pressure steam normally operates at 125 psi and is currently at 25 psi. This may cause a loss of humidity control for cleanroom and general lab spaces. PUPF have started 2 backup boilers to recover. At this time it appears that the building is stable with no shutdown of building systems is needed. I will update once campus steam is back to normal. Thank you, Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036 [Purdue_University-150_Years_of_Giant_Leaps] www.purdue.edu/giantleaps

BNC Fire Alarm Testing Friday Dec 6, 2019 From 5AM to 7AM
by Voorhis, Mark L. 04 Dec '19

04 Dec '19

Dear BNC Users, The Birck Nanotechnology Center will be performing fire alarm test on December 6, 2019 from 5AM to 7AM. Due to construction changes to the Center Purdue Fire Equipment Services (FES) will need to complete a building wide fire alarm test. This will involve all fire horns sounding and strobe lights flashing as if we were having a fire alarm. On December 6, 2019 at 5AM FES will make 2 announcements over the building wide public address system informing everyone in the center about the fire testing and not to evacuate the building. One announcement will be made 5 minutes before fire testing begins and a second announcement just before activating all fire horns and strobes. Once the fire test is complete then a final announcement will be made over the building wide public address system informing everyone in the center that the fire alarm testing is complete and to evacuate the building on future alarms. Thank you Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036 [Purdue_University-150_Years_of_Giant_Leaps] www.purdue.edu/giantleaps
