Why is lightning such a risk on a farm?
Lightning often strikes the tallest object in an area, and open fields leave tractors, people and animals standing out. Metal fences, wet ground and long conductors can carry current beyond the strike point. Storms also arrive quickly on warm days, and people who want to finish a job often stay out too long.
The National Weather Service publishes general lightning safety guidance and is a good place to learn the basics.
Even a mild-looking storm can produce dangerous lightning, and strikes can travel well beyond the rain, so the rule must not depend on how the sky looks.
What is the best rule for when to go in?
The simple message is to go indoors at the first sign of thunder or lightning, and wait a reasonable time after the last thunder before going back out. Local safety agencies publish specific waiting guidance, so check the National Weather Service. Do not wait for rain to begin, because lightning can strike miles away from the storm.
Set a firm farm rule: when you hear thunder, work stops and everyone moves to shelter. Make it everyone's rule, including the boss.
Teach children and visitors the same rule, and agree on a single shelter spot so no one is searching for each other when a storm is close.
- Go in at the first thunder
- Wait before resuming work, following official guidance
- Do not wait for rain
- Make the rule apply to everyone
Where is safe shelter?
A substantial building with wiring and plumbing offers real protection. A hard-topped vehicle with windows up is also much safer than open ground. Small open sheds, tents, open barns, pavilions and covered porches are not safe. Avoid touching plumbing, corded phones and electrical equipment during a storm.
If no shelter is available, move away from tall isolated trees, fence lines, water and high ground. Ask local emergency management about safer options for fieldwork far from buildings.
Inside a shelter, stay away from windows and avoid showers, sinks and washing dishes until the storm has passed.
What should you avoid while working?
Do not operate open-cab equipment in a storm. Stay off metal fences, wire and irrigation pipes. Do not stand near tall trees, poles or windmills, and stay away from water, including ponds and wet pastures. Leave ladders, grain bins and elevated work platforms before a storm arrives.
Plan tasks near the forecast. On days with thunderstorm chances, pick work you can walk away from quickly, and keep a phone or radio at hand for alerts.
- Open-cab tractors and mowers
- Fences, wires and irrigation lines
- Isolated trees, poles and high ground
- Ponds, wet fields and standing water
What about animals and equipment?
Livestock under isolated trees or beside wire fences can be killed by a strike. Shelter and pasture design can reduce the risk, such as shade structures that are not isolated trees and fencing that is grounded by a qualified electrician. Ask your extension office and a licensed electrician about lightning protection for barns and fencing.
Unplug sensitive equipment or use appropriate surge protection, and consider the risk to electric fences.
What do you do if someone is struck?
Call 911 immediately. People struck by lightning do not carry a charge, so it is safe to help them once the area is safe. If the person is not breathing and you are trained, begin CPR and use an AED if one is available. The dispatcher can guide you if you are not trained.
Move the person to safer ground if the storm is ongoing, but do not put yourself at risk. A first aid course through a local provider can prepare you for this kind of emergency. This is general education, not medical advice.
How can you build good habits?
Check the forecast each morning during storm season. Use a weather radio or phone alerts. Teach children and new workers the rule. Review what happened after any close call and adjust your habits.
The goal is not to avoid the outdoors but to leave the field early enough that lightning never gets a chance.
Share your rule with hired help, visiting youth groups and neighbors who help with chores, since people who are new to your farm may not realize how quickly storms can arrive.
Key takeaways
- Go indoors at the first thunder, and do not wait for rain.
- Use a substantial building or a hard-topped vehicle, not sheds, porches or trees.
- Avoid fences, open equipment, water and isolated trees.
- If someone is struck, call 911 and start CPR if needed.
