When the average daily temperature is above freezing, aeration fans should be turned on to cool the grain and remove excess moisture. Allow the fans to run several days to achieve the desired temperature throughout the grain profile. Shutting off the fans prematurely can result in uneven temperature profiles, which will increase the risk of future spoiling of the grain. If you find moldy or spoiled grain, remove grain from the bin until the problem grain is out of the bin. Anytime you enter stored grain, make sure to have someone with you.
Bridged grain can collapse and kill within seconds.
Do not enter any bin while grain is being loaded or unloaded.
