Millions of bushels of grains flow safely from field to storage during harvest each year, but one person trapped in grain can stop the flow in a matter of seconds. All too often, farm workers or family members suffocate beneath the surface of grain. In Iowa, newspaper accounts show that this tragedy is repeated several times a year. Poor harvest or storage conditions can increase the risks, such as in 1993, when 10 Iowans died in grain. The real tragedy is that many of these people did not understand the potential danger of handling grain.
