Basic Electrical Safety

Why are farm buildings riskier for electricity?

Barns and outbuildings collect dust, hay chaff and moisture, and animals chew and rub on wiring. Dust and bedding burn easily, damp air corrodes connections, and long runs from the house can mean voltage and overload problems. Add space heaters, stock tank heaters, fans and power tools, and the circuits may be asked to do more than they were built for.

Look at each building as if you were an inspector. Where are the outlets, the panel and the lights? What is plugged into what? Notice anything that is warm, discolored, loose or crackling.

What are the common warning signs?

Signs of trouble include breakers that trip repeatedly, fuses that blow, flickering lights, buzzing or sizzling sounds, a burning smell, warm or discolored outlets and switches, mild tingling when touching an appliance, and cords that feel hot. Any of these means stop using that circuit and have it checked.

Do not simply replace a breaker with a larger one or keep resetting it. A breaker trips to protect the wire, and overriding it invites a fire.

• Burning smell or discolored outlets: shut off power and call an electrician.
• Repeated tripping: reduce the load and have the circuit inspected.
• Tingling from equipment: unplug it and stop using it.

How does moisture change the rules?

Water and electricity are a dangerous pair. In wet or outdoor locations, equipment designed for those conditions and protective devices that shut off power quickly when current leaks are widely used. Ask a licensed electrician what protection suits your barn, milking area, wash area or pump house, and what your local electrical code requires.

Never handle electrical equipment with wet hands or while standing in water. Keep cords and tools off damp floors and out of puddles.

What can I check myself?

You can look, without opening anything live. Check that cover plates are in place, that outlets are not cracked, that cords are not frayed, that nothing flammable is stacked against heaters or panels, and that panels are accessible and dry. Label the breakers so you can find the right one fast.

Keep the area around the main panel clear. Keep a charged fire extinguisher suited to electrical fires near exits, and ask your local fire department about the right type.

Make a habit of looking up at the ceiling and down at the floor in barns. Cobwebs thick with dust around fixtures, droppings near wiring and signs of leaks overhead all point to places where wiring needs attention.

What work belongs to an electrician?

Panel work, new circuits, service upgrades, outbuilding feeds, buried wiring, generator connections, grounding and anything inside a live box are for licensed electricians where local rules require it. Rules about who may do electrical work and when permits and inspections are required vary by state, county and town.

Call your local building or permit office and ask what applies to your property, including farm buildings. An inspection protects you and your insurance.

What should I do in an electrical emergency?

If someone is shocked, do not touch them while they may still be in contact with a live source. Turn off power at the main if it is safe to do so, or use a non-conducting object only if you have been trained. Call emergency services right away. For a small electrical fire, only use a suitable extinguisher if you are safe and the exit is clear. Do not use water on an electrical fire.

After any incident, have an electrician inspect the circuit before it is used again.

How do I make a simple electrical safety plan for the farm?

Walk each building and write down what is plugged in, which breaker feeds it, what looks worn and what you would do if the power failed or a fire started. Label the main shutoff in each building and make sure everyone who helps on the property knows where it is.

Schedule a professional inspection of the main panel and outbuilding wiring, especially if the buildings are older, if you have added equipment, or if you bought the property recently. Ask the inspector to explain anything flagged, and ask for a written report.

Finally, keep a short list near the door: the electrician's number, your utility's emergency line and the fire department. In a real emergency, a list on the wall beats a search on a phone with a weak signal.
