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.

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.
