Lightning Strike Prevention Cheat Sheet

Lightning strikes are a significant threat, causing an average of 20 fatalities annually in the United States. (weather.gov) To minimize the risk of lightning-related injuries or fatalities, it's crucial to understand and implement effective safety measures.

1. When Thunder Roars, Go Indoors

The safest place during a thunderstorm is indoors. If you hear thunder, seek shelter immediately. Avoid open structures like pavilions or tents, as they do not provide adequate protection. (weather.gov)

2. Safe Shelters

• Buildings: Enter a substantial building with a roof, walls, and a floor.
• Vehicles: A hard-topped vehicle with windows up offers protection.

Avoid seeking shelter under isolated trees, as they can attract lightning. (weather.gov)

3. Stay Away from Electrical Appliances and Plumbing

While indoors, avoid using corded phones, computers, and other electrical appliances. Do not touch plumbing fixtures like sinks, bathtubs, or faucets. Lightning can cause electrical surges that travel through wiring and plumbing. (weather.gov)

4. Wait 30 Minutes After the Last Thunder

Remain in your safe shelter for at least 30 minutes after the last sound of thunder before resuming outdoor activities. Lightning can strike even when the storm seems to have passed. (weather.gov)

5. Outdoor Safety Measures

If you find yourself outdoors without immediate shelter:

• Avoid Water: Get out of bodies of water immediately.
• Stay Low: Avoid elevated areas and seek lower ground.
• Spread Out: If in a group, maintain a distance of at least 20 feet between individuals.
• Avoid Metal Objects: Stay away from fences, power lines, and other metal structures.

Remember, there is no completely safe place outdoors during a thunderstorm. (weather.gov)
