Four people were listed in critical condition after being exposed to a “lethal” level of carbon monoxide on the Far South Side on Wednesday night.
The four — whose ages and genders were not available — were exposed to the gas in a single-family home in the 300 block of West 107th Street, according to Fire Media Affairs. The stove burners inside the home were on full.
The carbon monoxide levels were measured at 1000 parts per million, a “lethal level,” fire media said.
They were taken to Little Company of Mary Hospital in Evergreen Park, Roseland Community Hospital and MetroSouth Medical Center in Blue Island, according to fire media.
Sustained carbon monoxide concentrations above 150 to 200 ppm can cause disorientation, unconsciousness and death, according to the U.S. Consumer Product Safety Commission.
