Build, inspect and label the room
Build exactly to the stamped drawings. Changes on site are a common reason safe rooms fail.
How
- Use a builder experienced in reinforced concrete or masonry. FEMA notes nobody may claim a product or contractor is 'FEMA approved' or 'FEMA certified', so ask for test reports and past projects instead.
- Book the inspections your permit requires, including any special inspection of anchors.
- Install the tested door assembly exactly as the maker's installation instructions say.
- Keep copies of drawings, door test labels and inspection records with your home documents.
- Keep the room clear of clutter. FEMA advises this so people can enter quickly and are not hurt by falling objects.
