Barn Fire Prevention

A barn holds fuel in the form of hay, bedding and dust, and its occupants cannot always save themselves. Prevention and planning matter more here than almost anywhere.

Why is barn fire prevention a special case?

Barns combine several risks: dry material, dust, electrical equipment and animals that panic. Fires can spread through hay and bedding quickly and fill the building with smoke before anyone is aware.

The first goal is to protect people. Animals can often be replaced or recovered from, but lives cannot, so the plan must tell everyone to stay safe first.

Because barn fires can go from small to severe in minutes, the plan has to be settled before anyone is faced with the decision.

• Dry hay, bedding and dust
• Animals that may panic
• Smoke that spreads before anyone notices

What should you check in the wiring and electrical systems?

Rodents, moisture and dust damage wiring, and old installations may not suit current loads. Have a licensed electrician inspect the barn, replace damaged cords and fixtures, and use equipment rated for dusty, damp locations.

Avoid temporary fixes such as cords strung across the floor or overloaded outlets. Switch off nonessential equipment at the end of the day where it makes sense, and check that fixtures are kept clear of bedding.

Keep electrical panels clear and labeled, and know where the main shutoff is so that a fire crew can find it easily.

• Annual inspection by a licensed electrician
• Replace damaged or chewed cords
• Protect fixtures from dust and moisture
• No permanent extension cord use

How do ventilation and cleaning reduce risk?

Dust is fuel, so keep fans, vents, rafters and ledges clean, and clear cobwebs. Good airflow helps keep moisture down, which also matters for stored forage. Ask a ventilation specialist or extension agent about suitable airflow for your barn.

Clean up spilled feed and old bedding, and store cleaning materials safely. Do not leave oily rags or fuel containers in the barn.

• Clean fans and vents regularly
• Clear cobwebs and dust from rafters
• Remove spilled feed and old bedding

What about heaters and heat lamps?

Use heating devices only as the maker directs and only for their intended purpose. Keep them away from bedding, hay and walls, secure them so animals cannot knock them over, and do not leave them unattended where that is advised.

Ask your fire marshal about safer options for your situation. Many fire departments warn specifically about heat lamps in animal housing.

Never use portable heaters on or near hay, and do not hang heat lamps by their cords.

How should hay and bedding be stored?

Store large amounts of hay in a separate building or well away from animals and people, where possible. The hay storage articles on this site and the extension resources describe moisture and heating concerns.

Keep fuel, chemicals and machinery out of the barn when you can. Keep access lanes clear around stored material.

If you store hay in an overhead loft, ask your local fire department and extension office about the risks of that arrangement.

• Store hay away from animals where possible
• Keep fuel and chemicals out of the barn
• Keep access lanes clear

What should your fire plan include?

Plan escape routes for people, keep aisles clear and make sure doors open easily. Practice what everyone will do, including who calls 911. Do not attempt to fight a spreading fire, and never go back into a burning barn.

Think about animals before an emergency: halters, doors, gates and a place to take them. Ask the local fire department and large animal rescue groups about training.

Hold a short practice walk-through in daylight so everyone knows where the exits are, even when the barn is dark or full of smoke.

• Clear aisles and easy-open doors
• Halters and a plan for animals
• A named person who calls 911

How do you work with your fire department?

Give them a tour so they know where buildings, water sources, gates and hazards are. Mark entrances and addresses, and keep roads open all year, including in winter.

Ask about water supply options, such as ponds or tanks, and what the department recommends for your area. Update them when you add or change buildings.

Share the location of hydrants, ponds or other water sources, and keep a clear path for fire trucks to reach them.

• Show the fire department the layout and water sources
• Update them when buildings change
