At Least 9 People Hospitalized After Being Overcome By Carbon Monoxide In North White Plains

NORTH WHITE PLAINS, N.Y. (CBSNewYork) -- Nine people were taken to the hospital Wednesday after being overcome by elevated carbon monoxide levels inside a North White Plains home.

It happened after someone was running a generator inside the bathroom of a multi-family home on Emmalon Avenue, CBS2's Tony Aiello reported.

The carbon monoxide detectors worn by firefighters registered at 400 parts per million inside the home, Aiello reported. Exposure at that level can cause death in three hours.

"We've ventilated the structure of all the remaining CO and we are in the process of determining next steps along with the building department and we've contacted the Red Cross for shelter for the occupants," said North White Plains Fire Chief Andrew Seicol.

Victims were treated for headaches, nausea and dizziness.

Thousands of residents in Westchester remain without power following last week's nor'easter.
