HILLSBORO, N.D.-Four people were injured his past weekend at the American Crystal Sugar factory in Hillsboro after chemicals accidentally spilled from a tank.
Emergency crews responded shortly after 8:30 a.m. Saturday to the sugar plant 2 miles north of Hillsboro. American Crystal workers were pumping nitric acid from a chemical container into a tank inside the plant when a fitting on the pump failed, Traill County Sheriff Steve Hunt said. Nitric acid spilled from the pump, sending four workers to the hospital, Hunt said.
The workers were taken to Sanford Hillsboro Medical Center by private vehicle but were released shortly after medical staff determined the injuries were minor, Hunt said.
"Basically, it was precautionary," he said.
The entire plant was evacuated for several hours, and workers were allowed to return later Saturday.
