Did you know . . .
Almost every state in the United States is subject to hurricanes, tornadoes, or both. These extreme windstorms can cause extensive damage to buildings, and they threaten the lives of building occupants.
FEMA, in cooperation with the Wind Engineering Research Center of Texas Tech University, has developed designs for wind shelters that homeowners can build inside their houses.
These shelters are designed to provide protection from the forces of extreme winds as high as 250 mph, including the impact of wind borne debris.
Extreme windstorms such as tornadoes and hurricanes pose a serious threat to buildings and their occupants in many areas of the United States. Tornadoes strong enough to damage roofs, destroy mobile homes, snap or up root large trees, and turn debris into damaging wind borne missiles have occurred in virtually every state. Hurricanes have affected all Atlantic and Gulf of Mexico coastal areas in the United States, including Puerto Rico and the U.S. Virgin Islands. Hawaii has also been affected by hurricanes. Even states not normally considered susceptible to extreme windstorms include areas threatened by dangerous high winds. These areas, typically near mountain ranges, include the Pacific Northwest coast.
Your house was probably built in accordance with local building codes that consider the effects of minimum design winds. These are winds that, according to building code requirements, your house must be able to withstand. However, a tornado or hurricane can often cause winds much greater than those on which local building code requirement are based. Your house may be built "to code," but that does not mean that it can withstand winds from extreme events. If you are concerned about wind hazards where you live, especially if you live in Wind Zone III or IV, you should consider building a shelter.
To protect its occupants, an in-house shelter must be able to withstand the forces exerted by high winds and remain standing, even if the rest of the house is severely damaged. Therefore:
The shelter booklet, Taking Shelter From the Storm: Building a Safe Room Inside Your House prepared byFEMA provides the information that you or your contractor will need to build a shelter that meets these requirements. The booklet includes:
