Given a large enough suspension of combustible flour or grain dust in the air, a significant explosion can occur. A historical example of the destructive power of grain explosions is the 1878 explosion of the Washburn "A" Mill in Minneapolis, Minnesota, which killed 18, leveled two nearby mills, damaged many others, and caused a destructive fire that gutted much of the nearby milling district. (The Washburn "A" mill was later rebuilt and continued to be used until 1965.) Another example occurred in 1998, when the DeBruce grain elevator in Wichita, Kansas, exploded and killed seven people. A recent example is an explosion on October 29, 2011 at the Bartlett Grain Company in Atchison, Kansas. The death toll was six people. Two more men received severe burns, but the remaining four were not hurt.
