In home: A basement offers the greatest safety. Seek shelter under sturdy furniture if possible. In a home without a basement take cover in the center of the house on the lowest floor in a small room such as a closet or bathroom or under sturdy furniture. In a manufactured/mobile home or vehicle: Leave and go to a substantial structure before the storm arrives. If there is no shelter nearby, lie flat in the nearest ditch, ravine or culvert with your hands shielding your head. At work or school: Follow plans to move to interior hallways or small rooms on the lowest floor. Avoid areas with glass and wide, free-span roofs. (Schools, factories and office buildings should designate someone to look for severe weather and initiate an alarm.) In open country: If possible, get into a sturdy building, or lie flat in a ditch or depression and hold onto something on the ground.
