Tornado Safe Room Design

With the Rash of Tornadoes caused by the Extreme Weather Conditions we have had recently in the US.  I put together a few Tornado-Hurricane Safe Room Designs and Options.  

The first Drawing outlines the basic components of the exterior walls and ceiling for building a safe room in an existing basement using CMU-Concrete Masonry Units generally called Concrete Blocks-Steel Door and Frame, Reinforced Poured Concrete Ceiling.

When Building a CMU structure it is highly advisable to add Steel Reinforcement- In the case of building for Tornado or Hurricane Save Rooms substitute No.4 Vertical Rebar for No.5 size rebar.

  • I’ll be honest there has always been something that bothered me about the Tornado Safe Room design that FEMA suggested. I was never worried about the Structural Ability of the Safe Room Design to not withstand a Severe Storm-it is the fact of being trapped in a Safe Room– like Jodi Foster in Panic Room.  Maybe I’ve watched too much tv?  I’d rather be safe than sorry.
  • The fact that 2 exits are not available-as is required of almost any home/room design was the Red Flag going off in my mind and when I finally figured it out I made some notes and a quick sketch and made a three CAD drawings of the idea to help you get a better idea of what I’m talking about.
Maybe its just me, but; I’d hate to survive a storm only to die of starvation because I couldn’t get out of a safe room in a basement of a home.  
 
I’ve seen too many horror stories (Hurricane Katrina in New Orleans) of phones not working, emergency personnel too busy to respond to all the requests…
  • There is also the added benefit in the building of the safe room with an exterior point to bring the building materials into the safe room.  This will help keep the labor costs lower as it will speed up the job production by reducing the man hours.
I now feel that I have a Safe Room Design Build Plan that I would build in my own home and am comfortable sharing and discussing the project in detail.
Feel free to email or call me for any design build assistance in building a Tornado shelter in your Home.

Limit of Liability:  The designs in this booklet are based on extensive research of the causes and effects of windstorm damage to buildings. Safe rooms designed and built to these designs should provide a high degree of occupant protection during extreme windstorms (tornadoes and hurricanes). Any substitution of either materials or design concepts may decrease the level of occupant protection and/or increase the possibility of personal injury during an extreme wind event.

Important Legal Notice

Because it is not possible to predict or test all conditions that may occur during extreme windstorms, or control the quality of construction, among other things, the designer does not warrant the design.
The designer neither manufactures nor sells safe rooms built from this design. The designers have not made and do not make any representation, warranty, or covenant, express or implied, with respect to the design, condition, quality, durability, operation, fitness for use, or suitability of the safe room in any respect whatsoever. Designers shall not be obligated or liable for actual, incidental, consequential, or other damages of or to users of safe rooms or any other person or entity arising out of or in connection with the use, condition, and/or performance of safe rooms from this design or from the maintenance thereof.
