Seek shelter in a protected home or building.
Avoid open fields or high terrain. If you are caught in the middle of a field and you feel your hair standing on end, squat down, put your hands on your knees and tuck your head down between your knees. Do not lie down or put your hands to the ground.
You should avoid areas such as lakes, beaches, boats, machinery, golf carts, motorcycles or bicycles. If at all possible, you should take shelter in a low-lying area or an automobile.
To avoid dangerous side flashes, you should stay away from trees, fences and power lines.
At home, you should avoid the telephone and other electronic appliances. Also, stay away from open doors or windows and all metal objects.
