Update: As of 3:15PM on Friday October 7th, the cleanroom is still closed. It will remain closed until at least Tuesday, at which point we’ll reassess it’s status. .. …The cleanroom remains closed at this time as the U of A trades continue to work on the failed components of our HVAC system. We apologize for any inconvenience this may cause, but for safety reasons we’re unable to allow any access to the cleanroom until the HVAC system has returned to normal. Our users are free to use the 10K lab as it is unaffected by the aforementioned issues. Any questions can be directed to Keith Franklin.
