Fire Safety in Farm Vehicles

Hot engines, dry crop residue, fuel and electrical faults can combine to start a fire. Prevention and a clear plan for getting away safely are the most important protections.

Why do farm vehicle fires start?

Heat from engines and exhaust, worn wiring, leaking fuel or hydraulic fluid and a buildup of dust or crop residue can all provide the right conditions. A spark or hot surface can ignite dry material very quickly.

Harvest time is high-risk because machines run hot for long periods in dry, dusty conditions.

Many fires start in places that are hard to see, such as behind shields or under bodywork, and may smolder before flames show. Regular cleaning and inspection find those hidden spots.

• Hot exhaust and engine surfaces
• Dust and crop residue buildup
• Fuel, oil or hydraulic leaks
• Worn or damaged wiring

How do I prevent fires?

Follow the manual's cleaning and maintenance schedule. Remove crop residue and dust from engine areas, exhausts, belts and bearings as directed. Fix leaks and damaged wiring promptly.

Keep machines clean at shutdown, and do not park hot equipment on dry grass or near buildings that store hay or fuel.

Pay particular attention during harvest, when crop material collects on hot surfaces within hours. Many machine makers suggest cleaning at set intervals, and the manual will say what applies to yours.

• Clean debris from hot areas as the manual directs
• Repair leaks and damaged wiring
• Check belts and bearings
• Park away from dry vegetation and storage

Where should fire extinguishers go?

Many farms keep an approved extinguisher on or near machines, in the shop and in fuel areas. The right type and size depend on the equipment and the hazard, so ask your fire department, NFPA or your insurance adviser. Do not choose from memory.

Check extinguishers on the schedule recommended by the maker, and make sure people know where they are and how to use them. Hands-on training from your fire department helps.

Keep extinguishers where you can reach them without passing the fire, and not in a place that will be blocked by the machine itself. Ask your fire department how to place them.

• Ask about the right type and size
• Check on the maker's schedule
• Train everyone who may need to use one

What should I do if a fire starts?

Your safety comes first. Get out of the machine, move away and call 911. Do not put yourself at risk to save equipment or crops. Small fires can grow in moments.

Training from your local fire department and guidance from NFPA explain what to do in more detail. I am not giving emergency procedures here, because they must come from official sources and practice.

Practice leaving the machine quickly and safely, including how to open doors and exits. Knowing your exit in advance saves time when a moment matters.

How do I keep fires from spreading to fields and buildings?

Keep firebreaks and clear areas near buildings, and keep water sources accessible if possible. Talk with your local fire department about how to reach your farm and where gates and water supplies are.

Make sure your address is clearly marked so responders can find you quickly.

Talk with neighbors about mutual aid in a fire season, and learn what your local fire department asks of farm owners.

• Clear areas near buildings
• Mark your address clearly
• Know where your water sources are

What about electrical and battery issues?

Faulty wiring and poorly installed accessories can cause fires. Have a qualified mechanic fit any new lights or equipment, and replace damaged cables. Keep batteries clean and secure and follow the manual for charging.

Do not use makeshift fixes such as wrapped wires or oversized fuses.

Do not store flammable materials, rags or trash near batteries, exhausts or electrical panels. Keep the cab free of oily rags and clutter.

• Have wiring and accessories installed by a qualified person
• Replace damaged cables
• Keep batteries clean and secure

How can a farm prepare in advance?

Walk through a fire plan with everyone. Where do people go? Who calls 911? How do you shut off fuel supplies safely? Ask your fire department to help you review these questions.

Include youth and seasonal workers. Practice calmly so that the plan is familiar if it is ever needed.

• Everyone knows where extinguishers are
• Everyone knows exits and meeting places
• Address is clearly marked for responders
• Fuel shutoffs are known to the crew
