Authorities in southeastern Pennsylvania say a carbon monoxide leak sent eight people to the hospital, two of them in critical condition.
Emergency crews in Montgomery County were dispatched to a Norristown row house just after 11 p.m. Saturday.
Officials said elevated levels of carbon monoxide were found in five homes, and the source was a generator running in the basement of one of the homes.
Norristown fire chief Thomas O'Donnell said power to the home had been shut off by the utility company on May 21 for nonpayment. He said the resident then bought a generator and was using that to power the home.
Fortunately, officials said, another resident had a working carbon monoxide detector that went off, and they called 911.
Officials said those hospitalized include a paramedic.
