Indoors

Retreat to a basement or interior room or hallway.

Windows, which are easily shattered into dangerous glass shards.

Retreat to the lowest refrigerators, which can fall on a person.

Heavy objects such as floor.

Crouch in a bathtub.

Exterior walls, which can fail in high winds.

Cover yourself with a mattress or sleeping bag.

Mobile homes, even those with anchored foundations, are unsafe in a tornado.

Outdoors

Find low ground and lie facedown with arms over head.

Cars. If caught in a car, park on the side of road. Keep seat belt on, and put head down below the windows.

Bridges. Wind speed increases under bridges.
