[Bnc-facility-notice] NOTICE - Loss of Campus Steam Pressure

[Voorhis, Mark L.]

Dear BNC Users

Things went from bad to worse, during the process of bring more boilers on line at the wade power plant one of the two remaining boilers tripped off, one of them being a very large coal burning boiler.  Our high pressure steam is 13 psi (normal is 125 psi)  and 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 humiditiy 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 a larger gas fired boiler but it takes time to start generating steam.

We will keep you posted.

Mark

Sensitivity: Private

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,
