Wbgen-ctb users:

after you have used the controlled temperature bath, please aspirate the
water in the bath and rinse the bath, the heating coil, the water
circulator and the plastic balls with water. Rinse the bath three times
and in the end aspirate the water.

Thank you,
Uli

Subject: keep the wet benches clean and safe
Message-ID: <3F9483A4.5253EDD3@snf.stanford.edu>

Dear wbgen and wbgaas users:

just a few reminders:

-Before you start using the wet benches, place all dried beakers and
labware on the appropriate shelf.

-Enable the bench.

-Always use transfer carts to transport chemicals; chemicals must never
be hand-carried in the lab.

-Every beaker or open container containing any chemical must have a
"In-use Hazardous Chemical" tag with it. Fill the tag out before you
pour chemicals in a beaker. Use complete chemical names on the tag (no
chemical formulas, no abbreviations, no BOE, KOH or "piranha").

- When working with chemicals, safety glasses, face shield, yellow
chemical resistant Nitril gloves over latex gloves and chemicals apron
should be worn.

-Place the chemicals far enough under the hood to prevent fumes from
escaping into the lab.

-Leave the benchtop clean and dry! Thoroughly rinse off any drips with
the DI hand sprayer and dry with the N2 gun.

-Log the approximate amount and composition of chemicals drained on the
station log sheet, located on the left side of the bench.

and once in a while, check out the operating instructions:

Please help me keeping the wet benches clean and safe!

Thank you,
Uli
