Abstract: Fire-resistant flexible dome (2) apparatus for covering and protecting buildings (6), goods, livestock, persons and other objects from a fire, especially a rapidly moving conflagration known as a "fire storm." In its preferred form, the apparatus comprises a dome-like structure (2) made of fire-retardant fabric, supported with air or gas pressure within integral tubes (40) radially disposed about the central axis, or between one or more layers of said fire resistant fabric. Said apparatus is rapidly deployed from its container (4), preferably located on the roof of the building (6) to be protected. Its ground-contacting periphery (13) is manually secured to the ground. In one embodiment, a liquid-filled circumferencial reservoir (24) integral with said ground-contacting periphery is provided to add an improved ground seal and added anchoring to ground to help maintain structural integrity.
