What are the biggest electrical hazards on a farm?
Overhead power lines are among the most serious. Tall equipment, ladders, irrigation pipes, grain augers and raised loaders can touch or come close to lines, and electricity can jump through the air. Damp conditions, damaged cords, overloaded outlets and old wiring in barns also lead to shock and fires.
Animals can chew cords, and dust and cobwebs add fuel to a spark. Walk your property with these hazards in mind.
Fences deserve a mention, since electric fencing and nearby lines can interact in wet conditions. Ask your utility and the maker of your fence charger how to place and ground the equipment safely.
How do I stay safe near overhead power lines?
Look up and note where lines run before you start work. Keep yourself and all equipment well away from them. Ask your utility company what clearance is safe for your equipment and whether lines can be moved or marked.
If equipment touches a power line, the safest choice is to stay clear and call the utility and emergency services. Do not touch anyone or anything in contact with the line, and keep other people back until the utility says the line is dead. Your utility can explain what to do and what not to do before you ever need it.
- Look up and plan routes before moving tall equipment
- Keep ladders, pipes and augers away from lines
- Call the utility before work near lines
- Do not touch anyone in contact with a live line
What should I do about outdoor outlets and cords?
Use outdoor-rated cords and fixtures only, with ground-fault circuit interrupters on outdoor and damp-location outlets. Test GFCI devices on the schedule the maker recommends. Do not use indoor cords outside and do not run cords through water, doorways or places where vehicles will crush them.
Do not overload outlets or daisy-chain extension cords. If a cord is warm, frayed or cracked, take it out of service and replace it. Do not use a cord with a missing ground pin.
Cover outdoor outlets, keep connections off the ground and unplug cords when you finish using them. Cords left outside wear out sooner from sun, water and animals.
How do I keep barn and shop wiring safe?
Barns collect dust, moisture and animal activity, so wiring needs weather- and animal-resistant fixtures, covered junction boxes and protected cable runs. Keep outlets and panels clear of hay, bedding and clutter.
Heat lamps, tank heaters and fans are common fire starters when used improperly. Follow the manufacturer's instructions, secure them out of animal reach and do not leave them near bedding. Ask your local electrician about safer options for your setup.
Rodents are a hidden cause of electrical problems in barns, since they chew insulation. Good housekeeping and pest control reduce the risk, and a licensed electrician can check for damage during routine visits.
When do I need a licensed electrician?
Hire a licensed electrician for new circuits, panel work, service changes, generators connected to a building, and any wiring in damp or dusty buildings. Local codes and permits often apply to this work, and your building or electrical inspector can tell you what is required.
Do not make improvised repairs to wiring. If you notice sparks, burning smells, tingling from metal fixtures or tripped breakers that keep tripping, shut off power if you can do it safely and call a professional.
What about storms, generators and downed lines?
Stay away from downed lines and anything touching them, including fences and puddles near them. Call the utility and keep others away. Never connect a generator to a building without a proper transfer switch installed by a qualified electrician, since backfeeding can injure utility workers.
Run generators outdoors, away from windows and doors, because their exhaust contains carbon monoxide. Install a carbon monoxide alarm in the house.
What routine checks help?
Once or twice a year, inspect cords, plugs, outlets, switches and fixtures for damage, and test GFCIs and alarms. Keep a record and fix issues quickly. Check electric fencing equipment according to the maker's instructions and keep it away from flammable material.
Teach everyone on the farm to shut off power, to call for help and to stay clear of lines. Post emergency numbers for the utility.
Write down where the main shutoffs are and mark them clearly. In an emergency, every person on the farm should know how to find and use them quickly.
Key takeaways
- Look up before moving equipment and keep clear of overhead lines.
- Use outdoor-rated cords and GFCI protection, and retire damaged cords.
- Keep barn wiring protected from dust, moisture and animals and watch heat lamps closely.
- Hire a licensed electrician for new work, panels and generator hookups.
- Stay away from downed lines and call the utility and emergency services.
