Acid neutralization system shutdown!

[John Shott]

SNF Lab Members and lab occupants in CIS-X:

The second neutralization tank has developed a slow-leak that is likely 
only going to get worse.  Accordingly, we are likely to have to shutdown 
this system for a period of approximately 12 hours sometime during the 
next few days.  During that time, all acids will have to be drained from 
wetbenches, the wetbenches will not be allowed to be used and the DI 
water system will likely also be off.

This is because tanks need to be drained and dried so that repair 
personnel can get in the 1000 gal fiberglass tank and make repairs.

We don't yet have this scheduled, but I wanted to let you know that this 
will likely be happening between now and early next week.

By tomorrow, you should be able to contact either Dick Crane 
(rcrane at snf.stanford.edu) or Leonard Chan (leonardc at bonair.stanford.edu) 
to learn more about the timing of this event.

We apologize for this, but feel that it needs to be addressed before it 
becomes a more catastrophic failure.

Thanks for your ongoing support,

John
