Farm fire preventions

Keeping your farm fire-free

There are a lot of flammable things on a farm. Chemicals, gas-powered vehicles and equipment, dry materials like straw, feed, chaff, and dust. Here are some tips for the best fire-prevention practices on your farm.

Fields and equipment

The Iowa State Extension has put together a list of safety precautions.

  • During harvest especially, carry a minimum of two Class ABC fire extinguishers: a smaller 10-pound unit in the cab and a larger 20-pound extinguisher at ground level on the combine. Give the extinguishers a shake once or twice a season to make sure the retardant inside is not compacted.
  • Have an additional extinguisher on each motorized piece of equipment used in the field.
  • Check engine fluid levels (such as coolant and oil) at the beginning of each day.
  • Blow leaves, dust, and chaff off the engine with compressed air or a leaf blower. Older combines can be particularly susceptible to collecting debris.
  • Make sure exhaust and other hot surfaces are free of combustible material, too.
  • If your equipment has a turbocharger shaft, check the pressurized oil-supply line to that shaft for areas that may rub from wear and start an oil leak.
  • If field welding on equipment is necessary, wet down the area under and around the implement first.


A barn can be a tinder box because so much of its contents are flammable. The National Fire Protection Association (NFPA) has created a barn safety checklist to help you practice good fire prevention “hygiene.”

Some highlights:

  • Heat lamps and space heaters should be kept a safe distance from anything flammable and should be sitting on a sturdy, balanced surface.
  • Make sure all wiring is in good condition.
  • Store feed, hay, straw, and flammable liquids in a different building.
  • Keep machinery and electrical and heat sources clear of cobwebs, dust, and grain dust.
  • Make sure exits are clearly marked and hold regular fire drills with everyone who uses the barn.
