Employees at Anchor Glass Container in Shakopee were back in the building shortly after 10 a.m. Friday following reports of an explosion that drew first responders from across the southwest metro. 

Nobody was injured in the explosion that destroyed the company's fire pump house. Anchor Glass Environmental Manager Travis Richins said Friday morning they are unsure what caused the explosion.

CenterPoint Energy cut all gas lines to the building, despite not knowing whether gas caused the fire. Richins told the Valley News Friday morning they are "unaware of a gas leak," contrary to previous reports from authorities, and are not yet sure what caused the fire. 

Shakopee resident and COKeM International employee Jane Hochhalter, who works across the street from the glass manufacturer, said the building shook and it felt like an earthquake had hit. 

Anchor Glass Container Corporation, located at 4108 Valley Industrial Blvd. N., off County Road 83 and State Highway 101, manufactures glass products like beer bottles and food containers. The Shakopee location employs about 290 people.

The fire started after the explosion in the plant's fire pump house, which stores equipment that would extinguish on-site fires. Richins said it's unclear whether production will continue in the near future as it could be unsafe to do so with that equipment damaged. 

"We don't know (if production can continue)," he said. "We definitely don't want to have a fire." 

The building was evacuated while first responders battled the flames. Employees may still be released for the day, according to a Shakopee police official. 

Construction on County Road 83 is underway next to the Anchor Glass plant. At one point, a bulldozer could be seen pulling an Allina ambulance out of the sand. 

Fire and emergency responders from Savage, Shakopee, Prior Lake, Chaska and the Mdewakanton Sioux Community were all on scene Friday morning.

The state fire marshal is investigating the incident.

Media reports indicate that another Anchor Glass Container location — in Henryetta, Oklahoma — dealt with a fire in mid-May. Fire officials said an oil leak in the plant's basement started the fire, which sent flames shooting from the building and damaged at least two shops inside, KTUL-TV reported.

This is a developing story and will be updated as more information becomes available.
