BNC is Open
by Weaver, John R 06 Feb '14

06 Feb '14

The Birck Nanotechnology Center is now open for full operation. We received our nitrogen delivery so the nitrogen system is back into normal operation. All hazardous gases are on, and all operations may be performed. FOR SPECIFIC EQUIPMENT STATUS, PLEASE CHECK CORAL. Some equipment may take a longer time to bring back into operation. Thank you for your understanding during this weather-related emergency. John John R.

BNC IS CLOSED UNTIL 1:00 PM TODAY
by Weaver, John R 05 Feb '14

05 Feb '14

DUE TO THE SNOW EMERGENCY, BNC IS CLOSED UNTIL 1:00 PM TODAY. The situation will be reassessed at that time. This means that NO HAZARDOUS WORK MAY BE DONE IN THE FACILITY. This includes any work at fume hoods. Hazardous gases will continue to be shut down. THE CLEANROOM IS CLOSED. You may NOT enter the cleanroom during the facility closure. Thank you for your understanding during this weather emergency. John John R.

ALL-USER MEETINGS POSTPONED
by Weaver, John R 21 Jan '14

21 Jan '14

NO ALL-USER MEETINGS TUESDAY, JANUARY 21, 2014, OR WEDNESDAY, JANUARY 22, 2014. Due to the tragic event today and the cancellation of classes today and tomorrow out of respect for the victim, the All-User Meetings will be postponed. Information will be provided when a new date is set. Our thoughts and prayers go out to the victim and all those affected by this event. John John R.

MORE GOOD NEWS: All Gases are On
by Weaver, John R 15 Jan '14

15 Jan '14

Effective 8:15 am Wednesday, January 15, 2014, all gases are ON in the Birck Nanotechnology Center. The appropriate purging has been completed and the facility is fully operational. Please note that some equipment may require further work to bring it to full function, so - as always - PLEASE CHECK CORAL FOR EQUIPMENT AVAILABILITY. Thank you for your cooperation and understanding during this weather-related shutdown and its aftermath. John John R.

GOOD NEWS! Nitrogen has been restored to the BNC
by Weaver, John R 14 Jan '14

14 Jan '14

The nitrogen lines have been purged, and both liquid and gaseous nitrogen is now available in both the cleanroom and laboratories. The BNC Cleanroom is now open. The toxic gas system is still being flushed, so hazardous gases will not be available until tomorrow (Wednesday). Some equipment needs to be purged for an extended period, so please check Coral for equipment availability. Thank you for your patience during this shutdown. While the chances of something like this happening again are very small, we are developing a set of contingency plans that should minimize downtime should there be a recurrence. We are also working with our nitrogen supplier to ensure that they have the appropriate plans in place to be able to support us. John John R.

Nitrogen and Cleanroom Update
by Weaver, John R 13 Jan '14

13 Jan '14

The truck that was supposed to deliver the nitrogen over the weekend did not make the delivery. Discussions with Linde (our nitrogen supplier) indicate that they had an internal communication issue and were very apologetic. They are hoping to make a delivery this evening. If that happens, we could be up as soon as tomorrow afternoon, but after the recent experience I won't feel comfortable about the delivery until I see the truck filling our tank! We will let you know as soon as we have solid information on when the cleanroom, hazardous materials, etc. will be operational. Thank you again for your patience. We are doing all within our power to bring the facility back to full operation as quickly as possible. John John R. Weaver Facility Manager Birck Nanotechnology Center 1205 West State Street West Lafayette IN 47907 (765) 494-5494 jrweaver(a)purdue.edu<mailto:jrweaver@purdue.edu> nano.purdue.edu

UPDATE: Weather-Related Shutdowns at Birck Nanotechnology Center Continue
by Weaver, John R 10 Jan '14

10 Jan '14

UPDATE We are scheduled to receive a nitrogen delivery this morning, BUT THERE IS NO CHANGE IN STATUS FOR THE FACILITY. The shipment will begin cooling the tank and all the lines, but will not be sufficient to complete the purging of the lines to bring us into operation. It will take at least one more delivery of nitrogen for us to recover our distribution capability. Please note that the restrictions listed in the previous e-mail will remain in place over the weekend. If we receive a second shipment on Monday (not yet confirmed), we may be able to resume normal operations within a few hours of the delivery. Today's delivery is a step in the right direction, but the nitrogen delivery system still must recover from the impact of the shutdown of the system during the storm.
