[Bnc-facility-notice] East Wing General Lab Ambient Temperature and Humidity Control

[Voorhis, Mark L.]

Dear East Lab Wing User,

We have completed the repairs on the east lab wing air handling unit and all labs ambient conditions are stabilized.  We had delays removing the original fan wheel shaft, Monday being a holiday, and making a custom fan wheel shaft by the machine shop (finish & delivered yesterday).

This has been a very unusual and difficult repair and the Physical Facilities Department and trades did an great job handling this issue.

Thank you for your patience during this unscheduled failure.

Best Regards,

Mark

Dear East Lab Wing User,

This morning there it was discovered there could be a motor or belt failure causing a serious vibration at the air handling unit that is transferring to the concrete floor causing vibration issue down into the lab areas.

We need to shutdown this air handling unit that controls ambient temperature and humidity for all the following labs and galleys.

We are not sure how long the down time will be until we complete the investigation of the unit and review parts needed.   For safety reason we plan to maintain normal BIO and chemical exhaust levels.  When you enter these lab spaces you may experience higher static pressure levels effecting how easy the lab doors will open.

We plan to shut down the unit at 10AM.  Sorry for the shut notice but we don't want to cause more possible damage to the Air handling unit.
