UPDATE:
Siemens is complete with the repair and testing of the new controls. Fume hoods are now operational.
ADDITIONAL INFORMATION:
With the lack of exhaust air in the building, many of the lab spaces may have issues with positive air pressure (relative to the adjacent space). This will cause the doors with mechanical closures to remain ajar. Unfortunately, this issue will persist until the exhaust shutdown is complete on Friday. Until then, the best solution will be to manually close any doors with automatic closures, especially those with access control (card readers).
Fume hood alarms can be silenced locally via the silence button located on the Operator Display Panel located on the front of the fume hood. (See photos)
Original Notice
Begin: December 13th, 2021 at 7:00 am
End: December 17th, 2021 at 5:00 pm
Building(s) or Area(s) Impacted: Lewis Integrated Science Building
Scope: Due to a failed fume hood fan system speed controller, the fume hood exhaust system will need to be shut down for (5) days. This will require all fume hoods in LISB to be placed out of service.
All containers within all fume hoods need to be closed in a manner that does not require exhaust air for safe storage.
Once the new controller is installed, the fans will be brought back on line for testing and calibration of the new controls. During this testing and calibration phase, the fans may start and stop at any time. During the scheduled shutdown, the fume hoods should not be assumed operational until an “All Clear” notification is sent out from CPFM Work Control.
Services Impacted: This will affect all fume hoods within the building.
Special Instructions: Fume hood sashes should be closed and containers within the fume hoods sealed prior to this date.
Extra Notes: EHS will be checking all hoods on Friday Dec 10 and taking them out of service at that time.
