Four people were taken to the hospital Sunday night after high carbon monoxide levels were reported in their Englewood home.
The 52-year-old woman, 22-year-old man and two children were taken to Holy Cross Hospital in fair-to-serious conditions, according to Fire Media Affairs.
A Level 1 Hazmat team was called to the 7100 block of South Winchester Avenue at 11:35 p.m., Fire Media Affairs reported, because of high carbon monoxide levels.
Carbon monoxide levels of 1,000 parts-per-million were recorded inside the home, about 20 times the recommended limit, a spokesman told the Chicago Tribune.
A generator was operating in the basement, and the residents did not have electricity, said Fire Media Affairs.
