Winds with 100 mph strength, tornadoes, and flying debris would threaten our safety, thus a tornado room with a design and engineering under ICC 500 and FEMA P-361 standards, has life safety features to protect us from these natural calamities.
It is observed that tornadoes are more common in the United States compared to any other countries. Statistics showed that there are four times more tornadoes in fact in the United States than all of Europe combined. Be informed too that the intensity, strength, frequency and amounts of reported tornadoes have increased over the years.
Every time a severe weather event occurs, the present trend is for more number per event and stronger tornadoes with higher winds would also occur. Thus it is observed that there is an increase of devastating costs and tragedies and damage and loss of life would accompany whenever winds of over 200 mph of multiple tornadoes would occur. Because of this, the International Code Council and the National Storm Shelter Association created the first Standard for the Design and Construction of Storm Shelters and safe rooms. With this move, there is an increased safe rooms in schools, tornado safe rooms and buildings with their designed built-in tornado rooms.
There are several reasons why a building has to have a tornado safe room. It is typical for a house to be built withstanding around 70 mph winds, and note that a tornado with around 70 mph winds would create damage and possible loss of lives, especially if your place or location is prone to hurricanes and tornadoes.
An example of a devastating tornado had wind speed rated at 318 mph, and this does not only cause safety concern and damage, but it also can create deadly flying projectiles and negative and positive wind pressure. With winds at those speeds, flying debris penetrated metals, roofs were lifted off, and buildings were separated from their foundations.
Codes are thus created by associations and agencies as a result of the many destructions in areas that are prone to severe tornadoes and hurricanes, encouraging communities to build their homes under ICC 500 building code. Numerous lives are said to be saved in buildings having either a tornado room or a storm room.
When you build a tornado room, sturdier walls, roof structures and tornado safe room doors would be involved. Consequently, the roofs of the building must be able to transfer wind loads to the walls and the walls to the ground or foundation.
Be aware that there are companies that would help you design tornado rooms with security in mind. You can then have safe room doors that are hidden above your ceiling with the sleek construction of this firm, resulting to a more open and airy design.
