All apartments in the building have an alarm. But Carbaugh’s was the only one that was triggered. Her children heard it and woke her up.

“They went upstairs into my apartment, read the levels.And they were high enough to where they had to evacuate the whole building.”

Firefighters said three buildings had carbon monoxide breakouts on the property.

Representatives for the property saidthey’re working with the city and an energy company to fix the problem.
