10 Essential Winter Electrical Safety Tips for Farms

| Farm fire prevention this winter

When temperatures drop, electrical systems on farms are pushed to their limits. Moisture increases, heaters run nonstop, equipment works harder, and dust accumulates, creating the perfect conditions for electrical failures, hot points, and barn fires.

According to industry experts, a large portion of electrical incidents on farms can be prevented with the right winterization steps, regular inspections, and proactive monitoring.

Here are 10 essential electrical safety tips to help you prepare your farm for the winter season and dramatically reduce fire risks.

1. Keep an Eye on Heaters

Heaters will work for longer periods. That also means: risks of overheating, dust accumulation, corrosion, and short circuits.

• Ensure propane or natural-gas heaters are approved for barn environments

• Verify they are professionally installed to code

• Inspect milk house heaters weekly (extreme humidity + heat = high-risk zone)

• Suspend heat lamps with chains or non-combustible supports

• Keep bedding and combustibles far away from heat sources

2. Replace or Eliminate Extension Cords

Extension cords are one of the most common hot points on farms.

• Never use them permanently

• Choose commercial-grade cords (not household)

• Replace frayed or cracked cords immediately

• Keep cords away from animals to prevent corrosion

• Watch for melted plugs or warm connectors, both signs of impending failure

Winter increases the risk: cords freeze, crack, or sit in moisture.

3. Hardwire Equipment & Install Waterproof Outlets

Moisture is a winter constant. And moisture + electricity create the perfect conditions for arcing and corrosion.

• Hardwire fans, lights, and equipment whenever possible

• If plugs are required, use NEMA 4X waterproof outlets designed for dusty and humid barns

• Check high ceilings and hard-to-reach fixtures (for dust + heat buildup)

This single upgrade can significantly reduce winter electrical risks.

4. Clean Lights, Panels, Motors & Surfaces Regularly

Winter means barns are closed tighter, and dust builds up faster. Dust acts like fuel when equipment overheats.

• Blow off lights, rafters, fans, and pipes weekly

• Vacuum enclosed electrical spaces

• Keep panels and motors clean and accessible

• Before welding or grinding, clean the area or keep it wet

5. Use a Thermal (FLIR) Camera to Detect Hidden Hot Spots

Thermal imaging is one of the most effective preventive tools for winter safety.

• Scan panels, motors, heaters, exhaust fans, and junction boxes

• Identify overloaded circuits or failing connections

• Check for hot bearings in conveyors, augers, or feed systems

• Monitor problem areas monthly during winter

Thermal cameras are now affordable, and can prevent a barn fire long before it begins. 

6. MOVe Combustibles Away From Electrical Sources

Hay, straw, oil, bedding, and dust are especially dangerous in winter as airflow drops and humidity spikes.

• Store combustibles in non-livestock buildings

• Keep piles clear of heaters, panels, and motors

• Check for dust buildup around outlets and junction boxes

7. Inspect Silo Unloaders, Pumps & Bedding Equipment

Other critical winter hot spots include:

• Silo unloaders

• Well pumps

• Bedding choppers

• Bale handling equipment

Cold weather stresses motors and increases startup loads.

• Check insulation on cables

• Listen for unusual noises or slow starting

• Ensure motors aren’t overheating under strain

• Clean dust and built-up material weekly

Winter is the season with the highest motor failures.

8. Control Moisture to Reduce Corrosion & Ground Faults

Moisture is one of the top three electrical risk factors

• Improve ventilation even during cold months

• Remove standing water and ice around equipment

• Inspect metal junction boxes for rust or swelling

• Ensure heaters don’t create condensation pockets

Pro tip: Always check areas near wash stations.

9. Test OUTLETS, Breakers & Emergency Shutoffs Before Peak Winter

January and February see the highest electrical load of the year.

• Test GFCI (ground fault circuit interrupter) outlets monthly

• Open panels only if qualified or with your electrician present

• Verify emergency shutoffs for parlours and equipment rooms

• Ensure breakers are appropriately sized and labeled

These checks prevent failures when animals and infrastructure need heat the most.

10. Work With Professionals & Use Real-Time Monitoring

Farmers are increasingly turning to proactive electrical monitoring to detect anomalies before they become emergencies.

• Ask your insurer for a risk review

• Schedule an annual electrical inspection

• Use a 24/7 monitoring system like PrevTech to detect:

  • Overheating circuits

  • Ground faults

  • Abnormal equipment behaviour

  • Load anomalies

Winter is the season when early detection matters most.

| Conclusion: Prevention Is the Best Winter Protection

Winter puts every electrical system on your farm under pressure. The combination of moisture, dust, cold starts, heaters, and heavier equipment use makes the season the highest-risk period for electrical failures and barn fires.

With the 10 tips above, and with a proactive monitoring solution, you can protect:

• your animals

• your people

• your buildings

• your operations

This winter, small problems don’t have to turn into big ones.
