WASHINGTON (WUSA9) - Eight people were transported to a hospital after they were exposed to carbon monoxide Sunday morning in NW D.C., said fire officials.
It happened in a three-story boarding house located in the 500 block at U St. NW.
When firefighters arrived, they found high levels of carbon monoxide inside the building.
Authorities believe the cause of the elevated levels were due a faulty furnace.
All injuries are non-life threatening.
