VP&S Condenser Water Service Disruption, November 16, 5 a.m. - 2 p.m.

The condenser water system serving the Vagelos College of Physicians and Surgeons Building will be temporarily unavailable from 5 a.m. until approximately 2 p.m. on Saturday, November 16, due to repairs.

During the shutdown, environmental boxes, supplemental air conditioning equipment, and air conditioning for freezer farms will be temporarily unavailable on floors 2 through 17. Additionally, air conditioning in the following areas will be impacted:

• VC 9-201 surgical implant suite

• PH 15-136 Stem microscope room

We highly recommend that all cold room doors are kept closed and access prohibited during this shutdown period. Typically, this equipment will maintain temperature as long as the doors are kept closed. Please note, placement of dry ice or cryogenic materials in cold rooms can create a hazardous, oxygen-deficient atmosphere and must be avoided. If necessary, please relocate critical materials to unaffected freezers for the duration of the shutdown.

We apologize for the inconvenience and appreciate your cooperation as we work to improve our facilities. For questions or concerns, please contact John Hession, plant superintendent, jkh2149@columbia.edu.
