I've setup a box of cloth booties for entering the hotlab.  They are
washable so please use them.  I also have some paper booties there if you
like using them, but it can be costly to keep stocking them up, plus the
fee to throw them away.

As per RPG, before you exit the hotlab please check yourself.  If the
cloth booties are clean of radiation, please put the them back to the box.
 I'll ask to get them wash every now and then.

All the fumehood pumps in the ISAC-I hot and cold labs got tripped off when the MCC-X was powered down (See ISAC WP#2011-03-30-5). No reaction process is done inside the  fumehoods, so the pumps are ok to be left off for now until the MCC-X work is done.

Tue Apr 12 12:00:52 2011:  The hot lab glove box regeneration was started yesterday (April 11, 2011).  "Before regeneration, the O2 level was 97 ppm, The H2O level was 47 ppm. After restarting circulation through the dry train, the levels immediately started dropping. At 11:30 today, the O2 was @ 1.76 ppm, the H2O @ 11.2 ppm." (Marik). 

All the fumehood pumps in the ISAC-I hot and cold labs got tripped off when the MCC-X was powered down (See ISAC WP#2011-03-30-5). No reaction process is done inside the  fumehoods, so the pumps are ok to be left off for now until the MCC-X work is done.
