Authorities in central Pennsylvania say exposure to carbon monoxide sent seven people to the hospital, two of them in critical condition.
LNP newspapers reports that emergency responders were sent just before 5 a.m. Sunday to a home in Lancaster Township.
The township fire department said in a post on its Facebook page that an odor of gas and high carbon monoxide levels were found throughout the residence.
Officials didn't cite a cause, but the post included a photo of a disconnected flue pipe.
The department said the incident highlights the importance of not only having carbon monoxide detectors as well as smoke detectors in a home.
