As we enter fall harvest, much of Nebraska is facing abnormally dry to severe drought conditions. Plus, this week we have been red flag warning for fire. With weather conditions ripe for quick-moving fires, the risk is heightened by modern farming equipment, which has become larger and more complex over the years. Today's combines — often made with synthetic materials — can easily catch fire, especially when hydraulic leaks or fuel spills come into contact with smoldering crop residue.

Recent studies have shown that most combine fires begin in the engine area, with 76.7% of incidents stemming from contact between crop residue and hot components like exhaust manifolds or turbochargers. When a fire ignites, it can spread rapidly, especially if fuel lines or hydraulic hoses rupture.

Fortunately, advancements in equipment design have improved fire safety features. For instance, newer combines have more powerful radiator fans and strategically placed air intakes to minimize the risk of flammable materials entering critical areas.

Preventing Combine Fires: Key Strategies

1. Keep Equipment Clean: Regularly clean your combine, especially around the engine and exhaust areas. Use battery-powered leaf blowers or air compressors to clear debris. Power washing can also remove grease and oil that may accelerate a fire.
2. Park Smart: Allow combines to cool down before parking them in sheds. If parking in the field, choose fire-resistant surfaces and consider creating firebreaks by disking areas around parked equipment.
3. Monitor Engine Load: Excessive stress on engines can increase fire risk. Be aware that newer engines generate higher temperatures due to emissions standards.
4. Check Bearings: Overheating bearings can cause fires. Use an infrared thermometer to monitor bearing temperatures and shut down the machine if temperatures exceed safe levels.
5. Harvest Responsibly: Avoid harvesting during extreme fire weather. Be particularly cautious between 2 and 4 p.m., when conditions are often the most dangerous.

Preparation is Key

• Start harvesting from the downwind side of fields to minimize fire spread risk.
• Keep a cell phone handy for emergencies.
• Carry a 10 lb ABC fire extinguisher in the combine cab, and remember the PASS technique: Pull the pin, Aim the nozzle, Squeeze the trigger, and Sweep across the base of the fire.
• Ensure all extinguishers are regularly checked and maintained.

What to Do if a Fire Occurs

1. Move the Machine: If safe, pull the combine into areas that have already been harvested.
2. Turn Off the Engine: This prevents the air intake from feeding the fire.
3. Call for Help: Dial 911 as soon as possible, providing clear directions for emergency services.
4. Contain the Fire: If the fire is beyond control, focus on preventing it from spreading to nearby vegetation.

Final Thoughts

While proper maintenance and awareness can significantly reduce fire risks, it’s crucial to remember that fires can still occur. Stay vigilant this harvest season:

• Clean combines regularly.
• Monitor engine temperatures and bearing conditions.
• Ensure effective communication among crew members.
• Prioritize safety over equipment — no piece of machinery is worth risking a life.

By taking these precautions, we can help protect our farms, our communities, and ourselves during this critical time. Stay safe out there!
