Indiana GM plant chemical blast injures 4 workers

A General Motors Co. spokeswoman confirms one worker has life-threatening injuries after a chemical explosion at GM's metal-stamping plant in Marion, Indiana.

Spokeswoman Stephanie Jentgen says "the situation is contained" and "everybody has been evacuated" from the plant about 40 miles south of Fort Wayne.

Marion Fire Department Assistant Chief Greg Yeakle tells the Marion Chronicle-Tribune that two other workers were hosed down at the scene by firefighters before being transported to Marion General Hospital. Another employee was washed down in a shower.

Yeakle says chlorine dioxide was involved in the explosion Tuesday afternoon.

GM spokesman Bill Grotz says an investigation is underway.

The plant employs about 1,600 workers and provides blanks, stampings and sheet metal assembly for cars, vans, trucks and SUVs to GM assembly plants across North America
