Abstract
A method of fabrication of an emergency shelter to be used under the floor of a residential or commercial structure. In the preferred embodiment, a prefabricated acrylic shelter is sized to accommodate at least one individual in a crouching or sitting position. The shelter is placed prior to the pouring of a slab foundation or the building of the floor in a pier and beam foundation. The shelter is preferably fabricated by vacuum forming a top sheet and a bottom sheet of ⅛ inch acrylic sheet on molds to form top and bottom sections which are then sprayed with an epoxy-fiberglass composition for reinforcement.
