Four people were being treated for carbon monoxide poisoning Monday after someone ran a power washer indoors on the South Side.
Authorities were called about 7:45 p.m. to a home in the 6600 block of South Albany Avenue in Marquette Park, a Chicago Fire Department spokesman said.
Firefighters detected high levels of carbon monoxide within the home, and took four people — including two children — to Holy Cross Hospital in good condition, the spokesman said. Someone within the home was operating a gas-powered power washer indoors.
Multiple other people at the home refused medical treatment, the spokesman said. The scene was ventilated and cleared an hour later.
