Lightning Safety Precautions

Lightning storms can cause severe safety issues for both spectators and athletes. If you hear thunder, experts say, begin preparation for evacuation.

If you hear thunder, begin preparing for an evacuation.

Before any practice or event, a specific person should be in charge of checking the weather forecast. Be aware of whether or not the National Weather Service has issued a thunderstorm warning or watch.

If you see lightning, consider suspending activities and heading for a designated safe location. At a minimum, by the time the "flash to bang" delay reaches 30 seconds, all individuals should have left the athletic site and reached a safe location. A safe location includes fully enclosed, substantial buildings or a vehicle with a metal roof and closed windows.

Personnel should not return to the practice or game area until at least 30 minutes have passed since the last lightning flash or sound of thunder. Each time someone sees lightning or hears thunder, you must reset the timer.
