A system and method provide portable protection against a fire. An expandable fire protection enclosure has at least a base enclosure member, an intermediate enclosure member and a top enclosure member. The enclosure members are nested in a transportable configuration. When needed, the expandable fire protection enclosure is placed on a surface and the enclosure members are pulled from the nested, transportable configuration to an occupiable, expanded configuration. The enclosure members are constructed from a thermally-resistant material such as thermal protection system (TPS) silica. The system may include a flexible barrier positionable around an inner perimeter of the base enclosure member. The system may be placed on a thermally protective blanket.
