Possible temperature, humidity, or chilled water problems today ....

SNF Lab Members:

We have just been notified that there have been some failures at the Central Energy Facility this morning that may have an impact on humidity control, temperature control, and/or cooling water.

They believe that chilled water service should be restored shortly with steam expected to return by about noon.  Because we use steam as a part of the temperature control system, we may see more fluctuation than normal in room temperature.  Folks in lithography, in particular, should try to keep an eye on this.

Thanks,

John

All,

Our Cogen plant tripped today, it is too early to say why but all Steam is lost, so room temperature control is lost, all autoclave service is lost.

Electricty has not been lost, we are currently getting a feed from PG&E which is our default supplier.

The chilled water supply pressure is good but has a supply temperature of 49*F-50*F which will allow a constant feed for the day. We have plenty of Ice in the pool should we lose chillers

 

All hands are on deck in Cogen to troubleshoot then restart the plant and there is no ETA of return to normal service.
