Grain Entrapment Emergency Response

Grain entrapment can happen quickly and rescue is extremely hazardous. If someone is trapped, call 911 right away. Do not enter the bin. This guide explains prevention in general terms and points to official training.

What is grain entrapment?

Grain entrapment occurs when a person is pulled into or buried by flowing or collapsed grain in a bin, wagon or silo. Grain can behave like a liquid, and a person can be trapped in moments. Bridged or crusted grain and vertical piles can collapse without warning.

Entrapment is a confined space emergency. This article does not provide rescue steps. Official guidance and trained rescue teams are the sources, and untrained entry has killed would-be rescuers.

Talk with your insurer, lender and neighbors about grain safety. Many communities have joined together to buy rescue equipment for their fire departments or share costs for training, and your extension office may know of programs.

What should you do if someone is trapped?

Call 911 immediately. Tell the dispatcher the exact address and that a person is trapped in grain, and follow their instructions. Ask the dispatcher about technical rescue teams that serve your area.

Do not enter the bin. Do not run or start equipment unless you have been trained and told to by professionals. Keep other people away from the bin. If the dispatcher or official procedures call for specific actions, follow them. Wait for trained responders, who have equipment for this kind of rescue.

Mark bins clearly with warning labels and keep a visible emergency number and address at each bin, so anyone can find it during stress.

• Call 911 immediately.
• Do not enter the bin.
• Keep people away.
• Follow the dispatcher and wait for trained responders.

Why is rescue so dangerous?

Grain exerts great force on a trapped person, and further collapse can occur during a rescue attempt. Dust, low oxygen and other hazards can also be present in bins. Untrained rescuers can become victims.

Specific rescue methods are taught to trained responders, and no short article can replace that. Ask your fire department about grain rescue training and equipment, and whether they have trained with farmers.

Remember that grain wagons, trucks and hoppers can also trap people, not only large bins.

How can you prepare?

Share your farm address and bin locations with your fire department, and invite them to see your bins. Many rural fire departments and extension programs offer grain rescue awareness training, and some may bring training equipment to farm groups. Ask what is available in your area.

Make a written plan for bin work, including who knows when someone enters a bin, how communication will work and how to call for help. Never work in or near a bin alone. Check the OSHA agriculture pages for guidance and rules that may apply, since they vary by situation.

If you manage hired help, make bin safety part of every training, in languages your workers understand, and make clear that nobody is expected to enter a bin without a plan.

• Share bin locations with responders.
• Attend grain rescue awareness training.
• Never work alone near a bin.
• Write down a bin entry plan.

How can entrapment be prevented?

The strongest prevention is to avoid entering bins whenever possible. Use methods that do not require entry to manage grain, and follow official guidance on when entry may be necessary. Lock out and tag equipment, and follow the safeguards that OSHA, NIOSH and university extension programs describe, and ask official sources and trainers which safeguards apply to your situation.

Do not walk on grain that is moving, crusted or out of condition. Spoiled grain and bridging create hidden danger. Ask experts for how to handle out-of-condition grain safely.

Keep children and untrained people away from bins and grain wagons. Lock bin access, and teach everyone never to play in grain. Specific equipment, procedures and limits must come from official sources and training.

What about families and community?

A grain entrapment affects families, crews and the community, including the responders. Support is available, and in the US people can call or text 988 for the Suicide & Crisis Lifeline. Talk with your clinic and faith or community groups.

Keep keys, ladders and access points to bins controlled, and tell family and workers exactly who may authorize entry and who must be told.

Where can you learn more?

OSHA's agriculture pages and NIOSH's agriculture program publish grain handling safety information. Extension offices and the National Education Center for Agricultural Safety provide education.
