CANNON FALLS -- The Rochester Fire Department's chemical assessment team was called to a Cannon Falls business after the accidental mixing of two chemical lead to a "dramatic chemical reaction" that injured one person.
The chemical assessment team, which serves 11 counties in the region, was called about 5:15 p.m. Thursday to 103 Mensing Way in Cannon Falls. By the time the six RFD personnel and a battalion chief arrived to Gemini Signage facility, the injured employee was not on scene.
The employee did require medical attention. The extent f the person's injuries were unknown but they were not believed to be life-threatening.
RFD personnel entered the building wearing protective equipment.
"The team was unable to determine the exact product created by the mixing of the chemicals; however, they were able to determine there was no longer any risk of further reactions," a news release from the fire department read. "Due to the dispersal of chemical products during the reaction, the building was found to be contaminated with residual product, making re-occupying the building unsafe until a professional contractor could clean the area."
The Cannon Falls Fire Department, as well as Cannon Falls Emergency Medical Service and the Minnesota State Fire Marshal's Office were also on scene.
