Please, for everyone's safety, cleanup after yourself. Wetbenches need
to be left clean, dry, and free of acid residue.

Yesterday, 4/23/01, a labmember was sent to the Stanford Hospital
Emergency Room for treatment of HF acid exposure. The exposure occurred
at the non-metal wetbench. The member noticed HF crystals on the bench
deck and 6:1 BOE lid. The previous user had not cleaned up after
him/herself. While rising and wiping down the bench deck, the member's
thumb was exposed to HF through a hole in his gloves. Calcium Gluconate
Gel was applied and no long term effects are expected.

Always clean up after yourself. Wetbenches are by their very nature,
wet. They are particularly in need of constant attention to drips and
spills. Upon completion of use, each area should be rinsed with DI and
wiped dry as required. See a staff member if there are questions. Use
appropriate personnel protection equipment if needed.

Lets work together to keep our fab a safety and clean place to work.
