Grains swell when wet so bin damage is likely; more so with soybeans. Bolts can shear or holes can elongate. Look for signs such as stretched caulking seals, doors misaligned or similar structural problems.
Check bins with stirring devices carefully. The bin must be perfectly round for them to work correctly.
Bin foundations can shift, float or deteriorate from flooding. Inspect structures and foundations carefully, and have an engineering evaluation for larger bins.
Expect electric wiring, controls, motors and fans to be ruined. Do not energize wet components. Be sure the power is off and locked out before touching any electrical components of flooded systems.
Wood structures will be hard hit and may retain mold and contaminants.
Clean facilities and grounds completely. Then do a careful food safety inspection before returning facilities to operation. Maintain records of cleaning.
