Three people suffered injuries Thursday in an explosion at 3M’s Hutchinson, MN, manufacturing site.
Emergency crews who communicated on the radio shortly after 1:30 p.m. reported no fire, and no situation involving hazardous materials.
There was no immediate chemical risk, and responders were cleared to work with the injured workers upon arrival, said Hutchinson Police Chief Dan Hatten.
Three people were hurt, two with minor injuries, one with serious injuries. One person was taken to Hutchinson Health by ambulance. That person was seen at the hospital’s emergency room, and then flown to Hennepin County Medical Center. Fanna Haile-Selassie, a spokesperson for 3M, said the wounds were not life threatening.
The incident was the result of a piece of equipment that experienced a “process upset” during a cooling operation, Haile-Selassie said.
There was no structural damage at 3M’s facility, Hatten said.
“What it is and what the cause is — it’s way too early to determine,” he said.
“Safety and security of our employees is our top priority,” Haile-Selassie said. “A small area of the plant has been shut down pending an internal investigation.”
