You think an extension cord is harmless. It is just a piece of plastic and copper, right? Wrong. In the agricultural industry, that simple orange cord is basically a ticking time bomb. A recent incident near Lunenburg, Nova Scotia, where a fire broke out in a chicken barn, is the latest reminder of just how quickly things can go sideways.
The fire caused damage and could have been catastrophic. Luckily, no people were hurt. But this wasn't an isolated event. Agricultural fires are often linked back to basic electrical failures. We often prioritize convenience over safety when setting up heaters or fans in barns. That mindset is dangerous.

The Real Danger of Temporary Wiring
When you run a high-wattage appliance like a heavy-duty ventilation fan or a space heater on an extension cord, you are pushing that cable to its limit. Most cords aren't designed for the constant, heavy draw of agricultural equipment. They overheat. The insulation melts. Suddenly, you have an arc fault or a short circuit.
In a barn setting, you have dust. You have cobwebs. You have dry bedding. It is the perfect environment for a spark to turn into an inferno in minutes. Additional information on this are explored by Wikipedia.
I have seen it happen. A farmer hooks up a temporary heater to keep chicks warm during a cold snap. The cord gets bundled behind a piece of equipment. It can't dissipate heat. The plastic jacket softens. One spark later, the whole structure is at risk.
Why You Can’t Trust That Old Cord
Don’t assume your cord is fine because it looks okay. Internal damage is invisible. Maybe it was stepped on by a cow. Maybe it was pinched in a door. Copper strands break inside the casing. This increases resistance, which creates heat.
If you must use power in an outbuilding, do it the right way.
- Install Permanent Circuits: If you need power for fans or lights, hire a licensed electrician to run permanent, conduit-protected wiring. It costs more upfront. It saves your business later.
- Use GFCI Protection: Ground Fault Circuit Interrupter outlets are non-negotiable. They detect imbalances and cut power instantly.
- Inspect Your Equipment Regularly: If you see a cord with a nick, a frayed end, or a plug that feels warm to the touch, cut it up and throw it away. Never try to repair a damaged extension cord with electrical tape. It is a fire trap.
Beyond the Fire Hazard
The Lunenburg case brings up another critical issue: farm security and risk management. This specific farm had already suffered a tragedy earlier this summer when someone broke in and shut off the ventilation fans, resulting in the death of 10,000 chickens.
When you look at the stress those farmers are facing, it is clear that managing a facility is about more than just keeping the birds healthy. It is about protecting every aspect of your operation. Electrical safety is one of the few things you can actually control. You cannot always stop a trespasser, but you can stop a fire caused by poor wiring.
Don't wait for a fire inspector to point out your violations. Take a walk through your barn today. Look at every single plug and socket. If you see a mess of extension cords snaking across the floor, fix it.
Your bottom line depends on it. Your animals depend on it. Stop cutting corners on electricity. It is not worth the risk.
