On Monday, 1/22/07, from 0700 to 0715, we will conducting a facilities 
test that will briefly (<1 min) shut down corrosive process gases such 
as HCl, Cl2, HBr, etc. Maintenance personnel will be standing by to 
reset the gases as soon as the test is completed. In general, the 
residual gas pressure in the supply lines is more than enough to 
maintain gas flow to the tools during this brief shutdown and the test 
will not be seen by tool users. The exception is high flow HCl in the 
EPIs.  We will check for any affected users prior to the test Monday
