Safety Measures Reduce Risks in Grain Facilities
The number of grain dust explosions in the U.S. remained stable in 2024, with nine incidents reported, causing two injuries and no fatalities. This is consistent with 2023, which also saw nine explosions but resulted in 12 injuries. The 10-year national average remains at 8.6 explosions per year.
Purdue University professor Kingsly Ambrose, who authored the report, emphasized that while injuries were fewer, the damage caused to facilities remains significant. "Considering the reduced number of injuries, the grain dust explosions are of low magnitude. But look at the damage it can cause to the facility in terms of downtime, repair costs and litigations," Ambrose said.
The explosions occurred at four feed mills, three grain elevators, one ethanol plant, and one corn processing facility. The identified ignition sources included smoldering grain, equipment malfunction, welding, and cutting work. In three cases, the cause was unknown.
Grain dust was the most common fuel source, responsible for six explosions. Other sources included smoldering grain and feed. The incidents were recorded in nine states: Illinois, Iowa, Kansas, Michigan, Minnesota, Nebraska, North Carolina, Tennessee, and Wisconsin.
Ambrose stressed that explosion prevention begins before harvest. Keeping equipment in good condition and conducting regular maintenance can help reduce risks. "Check for repairs so you don’t have any accidents," he advised.
Proper grain storage is also crucial, as poor aeration can lead to fungal growth, which increases the risk of smoldering and ignition. "Dust is no good, both for dust explosions and for human health," Ambrose noted. "Housekeeping is very important. Keep the place clean."
Experts urge grain facility operators to remain proactive in maintaining safety standards to prevent future incidents.
