The National Sunflower Association has some advice to help reduce combine fires. Sunflower is an oil-based crop, and fine fibers from sunflower seeds pose a constant fire hazard. To help reduce the risk this harvest season, be sure to keep a clean work area when harvesting sunflower. Blow the combine and grain dryer setup with an air hose daily. Also, try nighttime harvesting, when humidity levels are higher and keep a small pressure sprayer filled with water on hand in the combine.
