A chemical spill caused an evacuation at the Mount Sinai Hospital on Wednesday.
Sodium tert-butoxide, a hygroscopic powder, reportedly spilled around 11 a.m. on the 19th floor of the hospital, which is located on the 1400 block of Madison Avenue, near 100th Street.
The accident happened in a research lab area, which ABC reported is a non-patient care area.
Out of caution, 150 people from the 18th, 19th, and 20th floor were evacuated.
Since the area where the spill was located was a non-patient care area, the spill did not impact anyone. It is being reported that there are no injuries related to the spill, and the hospital says that no patients or members of the community were at risk.
The spill has been contained, and normal operations resumed on Wednesday afternoon.
