To all wbnonmetal users:

On Tuesday, April 3, 2001, I am going to shutdown the wetbench from 7:00-11:30
in the morning to clean it up (decontaminate) both the pots and cassettes.
Please do not turn on the heaters.

Please see me if there's a problem.

Folks:

Above the door, to the left, there is a series of lights:

            Heater (yellow)/Holding (green)
            Systen Power (red)
            Door Sealed (green)

The Door Sealed light is on when the spin/dryer is running. There is a
delay between the time the cassette stops spinning and the door un-seals.
Do NOT attempt to open the door until the green Door Sealed light goes
out. Then we won't have these problems.

Thanks.

Both sulfuric hot pots were inadvertently contaminated during
maintenance work.  The right hot pot is still down for a controller
problem.  The left hot pot is OK, but is undergoing decontamination.  As
of about 7 pm, the left hot pot had hot 5:1:1 H2O:H2O2:HCl in it.  When
it cools to 50 degrees, it can be aspirated.  Please rinse the pot
thoroughly with the DI sprayer.  Then you can fill with
sulfuric/peroxide and piranha-away to your heart's content.
