Responders were unable to reach the workers because of the height of the structure and there was no time to wait for a ladder.
According to officials, firefighters cut a hole in the window on the 37th floor and got to the two workers quickly.
Paramedics rushed the two men to the hospital.
Doctors expect them to make a full recovery.
