KANSAS CITY, Mo. (AP) — More than 100 employees have been evacuated from a General Mills plant in Kansas City.

General Mills spokeswoman Kelsey Roemhildt says firefighters and hazardous materials crews were called to the plant Wednesday morning after a carbon dioxide alarm went off.

She says the plant’s 110 employees were evacuated as a precaution and there are no reports of injuries.

She says the leak has been isolated and crews are assessing the area before allowing employees to return to work at the plant, which mills and packages flour.

The Kansas City Star reports that in 1994, a carbon dioxide leak at the facility killed a worker.
