New York (WABC) -- A fire broke out inside the airshaft of an apartment building on West 13th Street. A resident called 9-1-1 just before 8am on Sunday.
Fire officials say the fire started in the airshaft between the 4th and 5th floors of the building.
Residents evacuated the building quickly to the credit of a woman visiting from Chicago.
"The smoke, we just kept smelling the smoke, so we just kept knocking on the doors yelling, there was no fire alarms going off," said Yvette Golla, who was staying in the building with a friend.
One pregnant woman living in an adjacent building was taken to the hospital over concerns of smoke inhalation.
Investigators say the fire stayed within the walls.
The Red Cross is assisting residents whose apartments suffered smoke damage.
The fire reached 2 alarms and some 110 firefighters responded to the scene.
"We made it a second alarm, we had reports of extension on two floors, fourth and fifth, so better safe than sorry, we just got second alarm rolling, and that's always the right move," explained Deputy Chief Paul Mannix of the FDNY.
