Fire shelter and method

A shelter for protecting a person from fire and heat external to the shelter comprising:

• a base;
• a front wall extending up from the base;
• a right wall extending up from the base and alongside the front wall;
• a left wall extending up from the base and alongside the front wall;
• a rear wall extending up from the base and alongside the front wall and the left wall and opposing the right wall;
• a roof atop the front wall, the right wall, the left wall and the rear wall which together define a protected chamber from fire;
• the roof, the front wall, the right wall and the left wall each having a core made of a three dimensional metal matrix embedded in foam insulation with concrete positioned about the front wall, the right wall, the left wall, the rear wall and the roof;
• the concrete forming a continuous one piece concrete layer enveloping the roof, the front wall, the right wall, the left wall and the rear wall down to the base, the concrete layer forming a fire resistant seal with the base about the front wall, right wall, left wall, rear wall and the roof which protects the person in the chamber from the fire and heat of about 600 to about 700 degrees Fahrenheit for between about two hours to about four hours;
• a heat reflective layer disposed on an external surface of each of the front wall, right wall, the left wall, the rear wall and the roof;
• an inflammable layer in spaced relation to the reflective layer on each of the front wall, the right wall, the left wall, the rear wall and the roof forming an airgap between the inflammable layer and the reflective layer in each of the front wall, the right wall, the left wall, the rear wall, and the roof;
• inflammable heat resistant spacers attached to and between the reflective layer and the inflammable layer of the front wall, the right wall, the left wall, the rear wall and the roof which maintain the inflammable layer in spaced relation with the reflective layer to define the airgap;
• and fasteners extending through the inflammable layer, the spacers, the reflective layer and the front wall, the right wall the left wall, the rear wall, and the roof to fix the inflammable layer, the spacers, and the reflective layer in place with the front wall, the right wall, the left wall, the rear wall, and the roof;
• and
• a fire-resistant door disposed in either the front wall, the right wall, the left wall or the left wall which provides access to the chamber.
