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.
