Overview and Immediate Priorities
When lightning strikes, the most important actions happen in the first few seconds and minutes. Your priorities are to get to a safe place, protect life, and prevent secondary hazards. Lightning can cause cardiac arrest, burns, nerve damage, and traumatic injuries, so rapid assessment and treatment are essential. This guide explains where to take shelter, how to reduce risk in open areas, what to do if someone is struck, and how to plan for storms in advance. All advice is grounded in guidance from the National Weather Service, American Heart Association, and Red Cross.
Where Lightning Can Strike
Common Targets and Risk Environments
Lightning often strikes tall objects and areas with higher conductivity. Understanding typical strike points helps you choose safer locations during thunderstorms.
- Tall structures such as towers, poles, and antennas
- Isolated trees and high points in open fields
- Open water surfaces like lakes, ponds, and golf courses
- Conductors including power lines, fences, and bleachers
- Building perimeters, electrical wiring, and plumbing during indoor storms
Safe Shelters and Locations
Indoors vs Outdoors Protection
Substantial buildings with wiring and plumbing provide the best protection. Safe vehicle options include enclosed metal-topped cars with windows closed. Avoid shelters that are open-sided or do not meet specific criteria for lightning safety.
| Location Type | Verified Detail | Source Type |
|---|---|---|
| Substantial building | Structure with wiring and plumbing; interior rooms away from exterior walls and openings | National Weather Service |
| Hard‑top enclosed vehicle | Metal roof and sides with doors closed; avoid touching metal surfaces | National Weather Service |
| Open shelters | Structures like rain shelters and dugouts are NOT safe | National Weather Service |
Actions During a Thunderstorm
Behavioral Steps to Reduce Risk
Ahead of and during storms, adopt consistent habits that limit exposure. These steps cover movement, equipment use, and what to avoid when thunder is heard or lightning is seen.
- Seek shelter immediately when you hear thunder, see lightning, or observe threatening skies
- Stop outdoor activities, including sports, hiking, boating, and construction work
- Avoid tall, isolated objects; stay low in valleys but away from flood‑prone areas
- Stay away from windows, doors, porches, and concrete surfaces during indoor storms
- Do not use corded phones, plugged electronics, or plumbing fixtures if not necessary
First Aid and Emergency Response
Medical Care and Scene Safety
Lightning does not carry an ongoing electrical hazard, so you can safely touch a person who has been struck. Lightning victims often recover with no lasting injury, but some require immediate advanced care. Act quickly, monitor breathing and pulse, and activate emergency medical services.
Call 911 or your local emergency number. Begin CPR if the person is unresponsive and not breathing normally. Use an AED if one is available and follow its prompts. Treat burns, fractures, and bleeding with standard first‑aid measures while awaiting EMS.
Long‑Term Recovery and Follow‑Up
Health, Safety, and Property Guidance
Some effects of lightning are not immediately obvious. Delayed symptoms can include cognitive changes, sleep disturbances, mood changes, and ongoing pain. Property damage may affect electronics, appliances, and structures. Coordination with medical providers and insurers helps ensure thorough recovery.
- Seek medical evaluation for persistent symptoms such as headaches, dizziness, memory issues, or vision changes
- Document property damage with photographs, receipts, and inspection reports
- Coordinate repairs through qualified electricians and contractors familiar with lightning protection
- Review insurance policies for coverage details and claim procedures
Prevention and Preparedness Planning
Systems, Devices, and Habits
Long‑term protection combines reliable shelters, properly installed systems, and consistent habits. Planning reduces last‑minute confusion and increases safety during severe weather events.
- Install and maintain lightning protection systems, including air terminals, conductors, and grounding
- Use surge protectors for critical electronics; unplug nonessential devices during severe storms
- Create a written emergency plan with communication, meeting points, and supply kits
- Monitor reliable weather forecasts and alerts, especially during warm months and outdoor events
Summary Checklist for Lightning Safety
Quick reference of priority actions before, during, and after thunderstorms to improve decision‑making under pressure.
| Phase | Action | Why It Matters |
|---|---|---|
| Before | Identify nearest safe shelter and evacuation routes | Reduces decision time when storms develop |
| During | Move indoors or to a hard‑top vehicle at first sign of lightning or thunder | Lowers direct strike and side‑flash risk |
| During | Avoid open fields, water, tall objects, and conductors | Minimizes attraction and step‑potential hazards |
| During | If someone is struck, call 911, begin CPR if needed, use AED | Improves survival and recovery outcomes |
| After | Seek medical care for lingering symptoms and property damage | Addresses delayed health and financial impacts |
Frequently Asked Questions
- Can you be struck by lightning more than once? Yes. A previous strike does not protect a person or place from future strikes.
- Is it safe to shower or do dishes during a thunderstorm? It is safest to avoid plumbing and corded appliances during storms due to conduction risk.
- What should you do if caught outside with no shelter nearby? Move to a lower area, crouch on the balls of your feet with minimal ground contact, and keep away from isolated objects and water.
