Weather conditions have helped Union County wheat fields to mature – but these same conditions can lead to an increase in fires to tractors, combine harvesters, and crop fields.
Union County has already had a number of tractor fires this year. Officials offer two recommendations to prevent injuries and property damage – preventative maintenance and pre-planning for fire emergencies.
Ohio ranks fourth in the nation for combine fires. Other states leading the list include Minnesota (first), Iowa (second), Illinois (third), Kansas (fifth), Nebraska (sixth) and South Dakota (seventh).
The majority of tractor and combine fires start in the engine compartment. Contributing factors for heat sources include faulty wiring, over-heated bearings, leaking fuel or hydraulic oil. The dry crop residue makes a ready source for rapid combustion to occur when the machine is operated in the field. Birds and wildlife are known to make nests in the engine compartment or exhaust manifolds which can add fuel sources for unsuspecting combine operators.
Tips to prevent machinery fires:
• Have a daily maintenance plan during the harvest period. Keeping the machinery well maintained plays a large role in preventing fires from these sources. Cleaning up spills, blowing off chaff, leaves, and other plant materials on a regular basis, proper lubrication of bearings/chains, and checking electrical connections should be part of the daily routine. Farmers may choose to do their daily maintenance in the morning while waiting for the dew to burn off the crops. However, performing maintenance at night will highlight any hot-spots or smoldering areas as the machine is cooling down. Removing chaff at the end of the day will reduce the amount of debris available to spark a fire.
• Eliminate static electricity. A chain may also be mounted on the bottom of the machine to drag on the ground while in the field. This decreases the buildup of static electricity.
It’s important to have an emergency plan in place in case of a fire.
If a fire breaks out:
• Call 911 or your local first responders at the first sign of a fire. Don’t wait to know if you can contain a fire yourself, rapid response is important to saving valuable equipment. Tractor and combine fires are often in remote locations where a specific address may not be available and access is limited. Emergency response times will be longer in these situations.
• Have ABC fire extinguishers readily available. A 10-pound ABC dry chemical fire extinguisher in the cab or near the ladder of the cab is quick access to protect the operator. A second extinguisher (20-pound ABC) is recommended to be mounted on the outside of combines where it is accessible from the ground. It’s possible that one unit will extinguish a small fire; having the second unit will help with any additional flare-ups. Don’t forget to check that the extinguishers are fully charged at the beginning of the season. Not having extinguishers ready when needed leads to a helpless feeling of watching one of your most expensive pieces of equipment go up in flames.
• Field fires. Hot mufflers and catalytic converters from other vehicles driving in the field can pose a risk to the dry field fodder. Open burning on neighboring properties also poses a risk of stray sparks. Smoldering materials may go by 15 to 30 minutes before being noticed. A small gust of wind could rapidly turn that smoldering into a fire. In extreme dry conditions, a water truck may help protect against field fires. Never use water on fires that are electrical or fuel sourced.
• Have an emergency plan in place and discuss it with the other workers or family members. Knowing what to do in the event of a fire emergency is important. Knowing the address to the field and how to contact fire departments directly instead of through the 911 system are important safety conversations for the entire harvest crew.
Officials advise farmers not to get caught thinking it can never happen on your farm and to take preventative action.
