Black Building Advisory: Fume Hood Disruption, May 25, 2023, 4 p.m. - 8 p.m.

Fume hood exhaust fans will be temporarily unavailable on floors 15, 16, and 17 in the William Black Building on Thursday, May 25, 2023, from 4 p.m. until approximately 8 p.m. due to necessary repairs.

During this time, laboratory users on floors 15, 16, and 17 are instructed to avoid using fume hoods and tightly seal all containers within the fume hood or remove and safely store containers elsewhere in the lab.

Once service has been restored, Environmental Health and Safety (EH&S) will be on site beginning Friday morning to spot check fume hood exhaust flow and recertify the hoods.

We apologize for the inconvenience and appreciate your cooperation as we work to improve our facilities. If you have any questions or concerns, please contact Facilities Management at facilities@cumc.columbia.edu.
