MANHATTAN — Several floors of a residential building on Lexington Avenue and East 62nd Street were evacuated Monday night after authorities found higher-than-normal levels of carbon monoxide.
Firefighters evacuated residents from 797 Lexington Avenue shortly before midnight and allowed them to return at 1:54 a.m. when CO2 levels had dropped.
A broken boiler in the building may have caused the carbon monoxide levels to spike, according to the FDNY.
