Droughty conditions are present across many areas of the state and the outlook for October is for hotter and dryer than normal weather. Dry conditions present a fire hazard, and if you remember last year’s harvest we had several scares and total losses in our community related to fires. Already this harvest season we have had a couple of close calls with equipment.
Fall harvest is one of the busiest—and most hazardous—times of the year on farms. Dry conditions, combustible crop residues, and long hours in the field create an environment where fires can start and spread quickly. Equipment such as combines, tractors, and grain dryers are especially vulnerable. Taking precautions now can prevent costly and dangerous fires.
Common Fire Risks:
- Combines and Tractors: Accumulated crop residue on hot engine parts, bearings, or belts can ignite. Electrical wiring and worn bearings are also potential ignition sources.
- Grain Dryers: High temperatures, fine dust, and constant operation increase the risk of fire during drying season. Improper maintenance or overloading can worsen the hazard.
- Fuel Storage and Refueling: Spilled fuel or careless smoking around equipment is a common ignition source.
As a reminder, here are some prevention tips:
- Clean equipment daily to remove dust, residue, and crop debris from engines, mufflers, and bearings.
- Check wiring, belts, and bearings regularly for wear and overheating.
- Keep fully charged ABC fire extinguishers on each combine, tractor, and service vehicle. A water extinguisher or pressurized water, as well as tillage tools, can also be helpful for crop residue field fires.
- Allow grain dryers time to cool down before shutting off fans. Ideally they should not be unattended while in operation, but that is not always possible. Consider early-warning monitor systems (new technology can be linked to your phone to monitor the dryer from anywhere).
- Refuel only when engines are off and cool.
- Where possible, create defensible space around grain facilities by mowing weeds and keeping the area free of clutter.
Fires can spread rapidly in dry fall conditions. A few minutes of maintenance and vigilance can help protect your equipment, your crop, and your safety this harvest season.
