Multiple fire departments responded to a five-alarm fire at the Anheuser Busch can production plant in Arnold, Missouri, Tuesday night.

A spokesman for the Rock Community Fire Protection District said a call for a three-alarm fire at the Metal Container Corporation on Tenbrook Industrial Park in Arnold came in before 8 p.m. After crews arrived, it was updated to a five-alarm fire.

The spokesman said the plant had a power outage earlier in the day. When power was restored, a furnace caught fire. The fire then got into the duct work and firefighters are still working to pinpoint where the fire is in the facility.

"All our colleagues at the plant have been evacuated and are safe, with no reported injuries,” Gemma Hart, a spokesperson for Anheuser-Busch, told 5 On Your Side. “The fire department is on site and we are cooperating fully with them. We don't have any other details to share at this time."

One firefighter has been taken to the hospital with heat exhaustion.
