[Halld-jlab] Hall D power outage

[Timothy Whitlatch]

Hi All, 

The "long" power outage has been moved up to this Thursday (18Jun). It will go something like this; 

7:30am Thursday - Turn all power off to the Hall D complex (Tagger, service bldg, counting house, cryo bldg, Hall D) 
Note: Emergency lighting in the hall and counting house will be out for about 1 hr. Signage will be posted 

11:30am Thursday - Complete hookup of generator to power critical systems - previously defined critical systems will be powered (No air conditioning) 

5pm Friday - 5pm Monday - some time during this period the switch over to normal power operations will resume (no longer on generator power) depending on weather and unforeseen obstacles. 

Please do not go into these areas during the outage times unless absolutely necessary. Contact Tom Carstens if you need to enter. Pay attention to all signage. 

Please do not turn on any electronic equipment until the conditions in the hall normalize (Contact Fernando Barbosa before doing so). 

If all goes well, we will have normal conditions in the Hall by Wednesday (25Jun) morning. 

Cheers,
