Dear BNC Lab Users,

All labs are now open for use.  The lab area heating system that warms up the outside subzero air failed allowing below freezing air to enter the air handling system and tripped off manual freeze protection sensors.  The heating system is operational and all air handling system are operational. 

I want to thanks BNC staff engineering and PUPF trades that responded to the building alarms.  Also thank you for your patience during this bitter cold weather.

Best Regards,

Subject: [Bnc-facility-notice] NOTICE - The East and West Lab Wing Air Handling System Shut Down Due to Cold Temperatures

Both east and west make up air handling systems are currently shut down due to low temperature freeze protection tripping them off.   We have negative pressure in the atrium space increasing difficulty opening doors.  We have trades responding to the issue. 

Until future notice all general research labs (listed below) will be closed with no fume hood or hazardous processes.
