NEW YORK — Firefighters evacuated three floors of an Upper East Side hospital following a chemical spill Wednesday, officials said.
The firefighters were dispatched to the Fifth Ave. side of Mount Sinai School of Medicine near E. 101st St. about 10:30 a.m. after a report of a chemical spill on the 19th floor.
The FDNY ordered an evacuation of the 18th, 19th and 20th floors as a precaution. About 150 people were removed from the building.
The spilled substance was sodium tert-butoxide, a hazardous and flammable substance used in chemical testing, officials said.
A firefighter was taken to an area hospital with a minor injury after responding to the spill.
