Due to the urgency expressed regarding work in the cleanroom, we are modifying the holiday shutdown of the cleanroom. We are currently attempting to bring in a cleanroom buddy on Friday (at 2.5x pay), and will do spot-checks for people working alone during the holiday period. A person working alone with chemicals in the laboratories or cleanroom will receive an automatic two-week suspension. Since "cleanroom buddy" coverage will be limited, please plan on working with another certified user during the holiday period. The revised hours that the cleanroom is open and chemical processing in the laboratories is allowed are: Thursday, 11/23/06: CLOSED Friday, 11/24/06: 12:00 noon to 12:00 midnight (all chemical work requires another certified user present) Saturday, 11/25/06: 12:00 noon to 12:00 midnight (all chemical work requires another certified user present) Sunday, 11/26/06: 12:00 noon to 12:00 midnight (all chemical work requires another certified user present) Monday: NORMAL SCHEDULE RESUMES Thank you in advance for your cooperation during this holiday period when the University is officially closed.
