Subject: [BNC-all] Semi Annual Cleanroom and Lab PM - PLEASE READ
The cleanroom will be closed beginning 7:30
AM Tuesday, April 7, 2008, and is expected to reopen late Wednesday or early
Thursday. Also, the office, labs, and public areas will be affected
on Wednesday, April 8. Significant temperature (55°) and humidity
excursions should be expected during the day. In addition, on Thursday
April 9 no laboratory work involving exhausted hoods, biosafety cabinets or
enclosures, vacuum systems, and/or gas systems can be performed during that
time period. Electrical measurements may be performed if they are not
affected by significant temperature excursions in the room.
Please see the more detailed description of
the activities following:
The Birck Nanotechnology Center building will
be undergoing a semi-annual preventive maintenance and service on April
7-9. Air handling systems, exhaust systems and toxic gas delivery and
monitoring systems will be down beginning at 7:30 a.m. Tuesday, April 7.
The BNC staff will be performing appropriate preventive maintenance on the
process equipment at this time as well. Campus steam will be interrupted
for 6-8 hours resulting with very cool temperatures (55°) in office,
laboratory, public areas on April 8. Please dress accordingly for the
colder temperatures.
Therefore, all CLEANROOM research work will
be suspended until the maintenance activities are completed and all systems are
returned to normal.
In addition, the laboratory area of Birck
will also be affected by this systems maintenance. As such, all
LABORATORY activities that involve exhausted hoods, vacuum systems, and/or gas
systems will be down beginning Thursday April 9 from 7:30 AM till 4:00PM.
However, work that involves taking standard electrical measurements may be
carried out in the LABS provided that fluctuating air temperature and humidity
do not affect the readings.
It is anticipated that the building and
process tool maintenance will be completed by April 9, and selected research
equipment may become available on an individual basis beginning Thursday or
Friday.
Please check with appropriate staff members
for details on specific equipment.
The Coral screens will give you status
information on any equipment that is scheduled through Coral.
Please contact John Weaver or any staff
member if you have questions.
Thank you for your cooperation and
understanding during this important preventive maintenance shutdown.
