Lightning Safety
When a thunderstorm strikes, lightning is possible
- Close windows and doors.
- Listen to a battery-operated radio, NOAA Weather Radio or television for the latest storm information.
- Do not handle any electrical or telephone equipment.
- Avoid bathtubs, water faucets and sinks. Metal pipes can conduct electricity.
- Stay inside until 30 minutes have passed since the last clap of thunder.
If caught outdoors
- Try to get to a building or car.
- If no structure is nearby, go to an open space.
- Squat low to the ground, making yourself as small as possible. Do not lie flat on the ground.
- Be aware of the potential for flooding.
- Avoid tall structures, such as towers, telephone poles, fences and power lines.
- Stay away from rivers, lakes or other bodies of water.
If caught in a car
- Pull onto the shoulder of the road away from trees that could fall on the vehicle.
- Stay in the car with the windows up and turn on the hazard lights until the heavy rains subside.
- Avoid touching any metal in the car.
- Avoid flooded roadways.
- Drive only if necessary.
When lightning strikes a person
- A person who has been struck by lightning does not carry an electrical charge that can shock others.
- Call emergency medical assistance immediately.
- Check the victim for injuries.
- If the victim is burned, provide first aid. Look for burns where lightning entered and exited the body.
- If the person’s heart and breathing have stopped, give cardiopulmonary resuscitation (if trained to do so) until medical professionals arrive.
