A dramatic interruption to lunch, business meetings and possibly sleep as smoke on the 12th floor forces the noonhour evacaution of the Hilton hotel.
District Fire Chief Peter Saab says the source of the smoke was a chair on fire which was quickly exstinguished and the ventilation process began.
Saab says the full fire response is standard until they know what they are dealing with.
He says other calls coming in would be handled by the District Chief on duty and the apparatus that is left would be divided up depending on what is coming in at the time.
Officials began letting staff and guests back into the hotel before 1pm. The scene has been turned over to fire investigators and City police while elevator technicians and more assist the hotel in returning things back to normal.
