Grain Storage Structure Inspections

Regular inspections catch problems before they cause injuries or losses. This guide explains the general approach and when to bring in a qualified professional.

Why inspect storage structures?

Bins, silos and storage buildings age, and weather, loads and use take a toll. A small problem such as a loose bolt or a leak can grow into a failure if no one notices.

Inspections are also a safety habit. They give you a chance to spot hazards before someone has to enter a bin or climb a ladder to fix something.

Insurance companies and extension programs sometimes publish inspection lists that can serve as a starting point. Inspections do not replace training. Anyone who climbs or enters needs the right instruction first.

• Prevents surprise failures
• Reduces the need to enter or climb unprepared
• Protects stored grain and income

What can you look at from the ground?

Many things can be checked without climbing or entering. Look at the foundation, the walls, the roof, the doors, the ladders and the equipment connected to the bin.

Look for rust, cracks, dents, leaks, loose parts or anything that has changed since last time. Take photographs so that you can compare over time.

Look closely at places where water can enter, such as seams, roof edges and door seals. Moisture damages both the structure and the grain.

• Foundation and base
• Walls, seams and fasteners
• Roof, vents and hatches
• Ladders, cages and platforms
• Connected augers, power and fans
• Look for changes since the last inspection
• Take dated photographs

What do you do about ladders and heights?

Climbing is one of the main injury risks. Ladders, platforms and roof hatches should be inspected according to the manufacturer and official guidance, and anyone who climbs should be trained.

If a ladder or platform looks damaged, do not use it. Ask a qualified person to repair it.

For fall protection details, rely on OSHA and manufacturer information. Make sure the area under and around ladders is clear so that anyone who falls does not land on obstacles. Never use a ladder you doubt, and report damage to the owner immediately.

When should a professional be involved?

Structural problems such as bulging walls, damaged supports, serious corrosion or anything that suggests loss of strength call for an expert. A bin that holds heavy grain can fail suddenly.

Contact the manufacturer, a qualified inspector or a structural engineer. Do not enter or load a bin you think may be unsound.

When in doubt, ask an expert before the next fill. The cost of an inspection is small compared with a failure. Take a frank look at how much load and what kind of grain the bin was built to carry, and check the manufacturer's information before changing what you store.

• Bulging walls
• Damaged supports
• Serious corrosion
• Foundation movement

What about electrical and mechanical parts?

Wiring, motors and controls around bins can be damaged by moisture, dust and pests. A licensed electrician should deal with electrical problems.

Keep guards in place, and lock out equipment before inspecting or repairing anything with moving parts.

Have a plan for what to do if you find damaged wiring: stop, keep people away and call a licensed electrician. Pests and rodents can chew wiring, so check for signs of them as part of any electrical review.

• Wiring and conduits
• Motors and controls
• Guards and shields

How often should you inspect and what should you write down?

Frequency depends on use, age and manufacturer guidance, so check your manual and ask extension. Many farms inspect before filling and at other times during the year.

Keep a written log of what you found and what you did. A log helps you spot patterns and share information with advisors, insurers and officials.

Share the log with the person who takes over when you are away, so that nothing is forgotten. Review the log each season and decide what to repair first.

• Before filling
• After storms
• Whenever something looks different

Where can you learn more?

Manufacturers, extension services, OSHA and NIOSH publish guidance on storage safety. Insurance providers may also have checklists.

If you find a hazard that could harm people right away, keep everyone away and get qualified help. In an emergency, call 911.

If the structure is old or the maker is no longer in business, extension and engineering professionals may still help you judge its condition.

• Manufacturer manuals
• Extension storage guides
• OSHA and NIOSH pages
