As you may have heard, the campus lost power this morning. One aftereffect of the power loss was the loss of campus-wide steam. To keep the cleanroom at a positive pressure and to prevent other building issues, we had to shut down all exhaust systems in the building. Because of these issues: The cleanroom is closed - please do not enter No chemical processing is allowed in the laboratories - even simple solvents Temperatures will be highly unstable. Do not run temperature-sensitive equipment or processes. The best prediction from Purdue Physical Facilities is that the steam should be stabilized in 3-4 hours from now, approximately 4:00 pm. Obviously that is an estimate - I will keep you posted as I learn anything new. Thank you for understanding. John Weaver Facility Manager Birck Nanotechnology Center
