When grain is stored wet, it ferments and produces this colorless, odorless gas. Oxygen is pushed out of the bin by CO 2 . If you are in this environment, CO 2 will get into your bloodstream and slow your breathing. If you suspect that this gas is present, don't go inside the bin. Try to force air through the bin by opening any doors or manholes.
Spoiled grain can also produce mold spores that become airborne when disturbed.
To prevent injuries and illness, you should follow certain safety precautions. Keep children away from areas where grain is being handled. Check inside the bin or wagon before turning on the power to the auger. Install ladders inside all bins. If it is necessary to enter a bin, shut off and lock out power before entering the bin.
