Powered up the three smaller cleanrooms this morning around HAM6. This afternoon (15:15) powered up the big cleanroom over HAM6. 

   These cleanrooms need to run over the weekend to be ready for next weeks vent. If there is commissioning work over the weekend that need the cleanrooms off, feel free to power them down. Please power them back up when finished.  

   For the small cleanrooms, simply unplug them.
   For the big cleanroom over HAM6, pull the wooden handled wire that is attached to the switch located on top of the SW corner of the cleanroom to shut it down. (see photos) To turn it back on, use a large ladder to reach the switch, and push it into the up position. 

   Note: the light in the big cleanroom is switch off.
