6 hospitalized after CO leak in Marquette Park home

CHICAGO (WLS) -- High carbon monoxide levels sent six people to the hospital in the Marquette Park neighborhood Thursday morning, the Chicago Fire Department said.

At about 1:50 a.m., paramedics responded to a person suffering a medical emergency at a house in the 3400-block of West 64th Street, according to the Chicago Fire Department. Paramedics tending to a sick person inside the house found out that the ailment in fact arose from a carbon monoxide leak.

Carbon monoxide alarms on firefighters' uniforms began going off, alerting them to a life-threatening leak, CFD said. CO Levels inside the home exceeded 1,000 parts per-million.

Two people were transported in serious-to-critical condition and four others were transported in fair-to-serious condition, CFD said.

Building inspectors are investigating the cause of the leak.

In another carbon monoxide leak on the Southeast Side, a boiler leak in the basement of an 18 unit apartment building at 87th Street and Paxton Avenue caused an early morning evacuation for residents.

The CO levels were 100 parts per million in the basement and first floor and 30 parts per million on the other two floors. No injuries have been reported as a result of that leak.
