Failure to do so will result in suspension from the labs and cleanroom. Stephen E. Jurss CIH, CSP Safety Manager Cleanroom Chemical Exhaust Shut Down To add chemical exhaust for the future laboratories, a required shut down of our solvent and acid exhaust systems for the BIO cleanroom and main cleanroom are needed. This interruption will require shut down of all toxic gases, cleanroom fume hoods, and cleanroom chemical research equipment. The general laboratories will not be affected by this interruption unless research requires toxic gases. The exhaust shut down is planned for January 7, 2014 from 7 AM to 4PM. The exhaust fans will remain running but the static pressure will drop below safety limits when the sheet metal contractors cut into the main chemical exhaust ducts. Please let me know if you have any questions or concerns. Mark Voorhis Building Manager CLEANROOM: The cleanroom will be shut down on Tuesday, January 7, 2014, from 7:00 am to 4:00 pm. No one is allowed in the cleanroom during this period. HAZARDOUS GASES: No hazardous gases will be available in the building during this period. BIOCLEANROOM: No exhaust will be available in the bio cleanroom. Non-chemical activities may be carried out. GENERAL LABORATORIES: General laboratories will operate as normal, but no hazardous gases will be available. Holiday Closing Purdue University will be closed January 1st.
