About the facility
The Cargill plant in Wahpeton specializes in the production of high-fructose corn syrup, corn gluten feed, and corn oil. The facility has been operating since 1996 and employs approximately 125 people. Production sites of this type handle organic dust — one of the most common sources of explosion hazards in the food and agricultural industries. Dust in drying chambers, conveyors, and silos can form an explosive atmosphere at certain concentrations, requiring systematic monitoring and reliable explosion protection systems.
