Foundation and Anchoring Criteria for Safe Rooms

The FEMA Fact Sheet provides detailed information on foundation and anchoring criteria for prefabricated safe rooms to protect individuals during tornadoes. The document specifies that safe rooms must be designed, manufactured, and installed according to FEMA P-361 and the ICC 500 standard. It outlines the structural requirements for safe rooms to resist various loads like wind, roof live, wheel, hydrostatic, and flood loads. Special attention is given to foundation design, anchor installations, and post-installed anchors to ensure the integrity and safety of the safe rooms.
