Five people were taken by ambulance to Philly hospitals and dozens more made the trip on their own after being sickened by carbon monoxide overnight at a Days Inn hotel.
During last night's storm, the hotel, which is located along the Roosevelt Boulevard in the Crescentville area, lost power.
Staffers turned on a generator in the basement.
According to police on the scene, that generator filled the building with carbon monoxide, which is a colorless, odorless, tasteless and potentially deadly gas.
Shortly after midnight, people began to get nauseous and dizzy. The hotel was evacuated as emergency crews arrived and took over.
Close to 100 people are currently staying at the hotel.
The building was aired out and people were allowed back in before daybreak.
