Tomorrow (Tuesday, October 11) AND Wednesday, October 12 will be our semi-annual air handling system maintenance shutdown. The entire building air handling system in MJIS will be turned off. ALL chemical hood activity, biosafety cabinet activity, autoclave work and activities in wet labs will need to STOP by 5 PM on Monday, October 10th and extend through Wednesday. (This stoppage includes Monday and Tuesday overnights!) Any chemicals stored in the hoods will have to be sealed at that time. Signs will be posted on all hoods to remind users not to use the hoods Monday evening, and removed when the maintenance work is completed and normal operations can resume, sometime on Wednesday. Please DO NOT use chemicals in the lab areas that you would normally use in the hoods. Temperatures in offices and meeting rooms will be unpredictable, so dress accordingly. Note that, due to additional work being done on Wednesday, any system that uses air ventilation (including any procedures utilizing gasses, anesthesia, etc.) will not be able to resume until Thursday.
