An economical, prefabricated, above ground "storm shelter "or "safe room" for personal protection from hurricanes, tornadoes, and other high wind events. The structure meets all FEMA guidelines for providing resistance to winds in excess of 250 mph and preventing missile penetration through the walls from airborne debris. The shelter can be installed inside of an existing room on concrete slab such as a garage or outside on a concrete slab constructed specifically for the shelter. The storm shelter walls are constructed of steel C-Channel components stacked and bolted in a horizontal configuration. The roof consists of angle iron for supports or rafters, and flat plate for the outer sheathing. The door is made from an assembly of flat steel plate, bar grating, flat bar cross members, hinges, and locking brackets bolted together. The locking mechanism consists of three locking pins attached to a locking bar for single action panic proof locking capability.
