"Nearly 11,500 fires in agricultural storage facilities-barns, stables, silos, grain elevators-are reported each year. These fires cause an average of 100 injuries, 10 fatalities, and $249.7 million in property loss. Silo fires are particularly difficult for firefighters and have proved deadly in the past. Agricultural storage fires are less deadly than other fires, but they cause five times more damage (Figure 1). This may be due to the loss of revenue that results from the destruction of agricultural goods in combination with structural damage to the storage facility itself."
