"What is a Safe house?"
Damage observations were conducted in Garland and Rowlett after the tornado. The observation team from APA focused on the performance of recently constructed homes, because these homes tend to contain newer materials, larger interior spaces, and more open floor plans that may have an effect on structural resistance to wind forces.
It is difficult to learn much, if anything, from homes that are completely or mostly destroyed by EF4 level tornadoes. For this reason, damage assessment was mostly limited to those in the lower EF0 through EF2 tornado wind speed ratings. These wind speeds are typical in the periphery zones of a large tornado.
Weaknesses in common
In most cases, engineers can point to one of several common weak links as the cause of structural failure and damage in this event. Observations of the tornado damage found that structural failure was often due to a lack of adequate connections.
A continuous load path, the flow of forces through a structure and the connections from the roof coverings and siding (exterior cladding) to the framing and to the foundation, must be provided for reliable building performance. Most of the observed failures were a result of poor continuity along the structural load path, often due to improper connections.

Fire is the sixth leading cause of unintentional-injury-related death over all ages. About 2,200 deaths were caused by burns and injuries related to fire in 2013. Often fires start at night when family members are asleep. A working smoke alarm will cut the chances of dying in a fire in half.National Safety Council
The Consumer Product Safety Commission says about 170 people in the United States die every year from carbon monoxide produced by non-automotive consumer products. Exposure also can result in permanent neurological damage.National Safety Council
