From mtang at stanford.edu Mon Jun 9 18:32:57 2008 From: mtang at stanford.edu (Mary Tang) Date: Mon, 09 Jun 2008 18:32:57 -0700 Subject: Fire (yes, FIRE!) at wbgen Message-ID: <484DD9C9.4070900@stanford.edu> Dear wbgeneral users: Yes, for those of you who missed the excitement, there was a fire this past weekend at wbgeneral (see Coral maintenance history for the details.) This is a serious matter. On study by an insurance company found the semiconductor industry to be vulnerable to fires -- because of the heated chemicals at wet benches. So, we'd like to remind you of the following when using the hot plate at wbgeneral (the operating procedures have been updated accordingly): 1. Enable the hot plate on Coral (wbgen-hpr) 2. DO NOT turn the heater. 3. FIRST, place your glass or quartz beaker on the hot plate, making sure it is filled with your chemical. *4. Do not use beakers made of materials other than glass or quartz which may melt. * *5. Do not heat an empty beaker. * *6. Do not walk away from the station when heating. * *7. *Place a thermometer in the solution (make sure it is compatible with your chemical). 8. Start heating with the heater setting at "2"; this will heat up approximately to 60 C, depending on the volume and beaker. If required for your process, ramp the temperature setting up *SLOWLY*. If unattended, the hot plate will shut off automatically after two hours. For the long term, hardware changes are under discussion (remote digital control, remote thermometer, etc.) Your opinions would be appreciated. For the immediate future, MAKE SURE TO OPERATE SAFELY! If you have any questions about your process, contact Uli. ANY questions... Remember Southampton University (http://www.theregister.co.uk/2005/10/31/south_research_fire/) Your SNF Staff -- Mary X.

The Neutralizer is down until the morning. Cesar got the system back into spec manually, and Tony Padilla came in from vacation to look at the system. Jose will take care of it in the morning. It's critical that no chemicals be dumped. If the pH goes out of spec in the neutralizer tanks, then the neutralizer must divert ALL water to a holding tank, that will quickly fill up and overflow. Even if noone is dumping water from the lab, the scrubbers and other facilities continuously feed (almost pure) water to the system. So if we upset the pH in the system even slightly, we create a very bad overflow situation.
