IMPORTANT SHELTER DESIGN ELEMENTS OF "ALL HAZARD SHELTERS":

There are essential design elements you should consider before purchasing an "All Hazard Shelter"™.

‘All Hazard Shelters’ must withstand violent earth movement from severe earthquakes; high velocity winds from tornados and hurricanes; invasion from mobs; heavy overpressures from nuclear blast; all types of radiations; wild fires; and air contamination from fallout and chemical and biological war gasses.   It is interesting to note that NBC shelters satisfy the entire scope of requirements for 'All Hazard Shelters'.

Before purchasing a shelter, do a careful 'risk assessment' for your location (see 'getting started'), and design your shelter accordingly.

If you choose to purchase an 'All Hazard Shelter', your shelter design must meet the following criteria:

  • Does the shelter provide critical radiation attenuation properties for NBC shelters?
    • Small diameter entrances.
    • Entrances with both vertical and long horizontal components connected with a 90-degree turn, assuring the proper attenuation of gamma radiation.
    • Long horizontal runs providing an area in the entrance for the required 6 feet of shielding assuring protection from initial radiation.
    • Shielding over the shelter chamber equivalent to 4 feet of dirt cover for gamma radiation, and at least 8 feet of dirt cover in blast areas, for shielding against initial radiation.

  • Is the shelter constructed of a material and geometry that will provide proper blast and earthquake protection?
    • Proper depth of cover for MAXIMUM blast protection (depth of overhead cover equal to the diameter of the shelter) assuring blast protection from overpressures to 200 psi.
    • Proper depth of cover to achieve stable and comfortable interior air temperatures, assuring survival from extreme weather conditions.
    • Arched ceilings that will provide ‘Earth arching’, assuring protection from catastrophic failures associated with soil burdens and high blast overpressures.
    • Construction material that will MOVE and BEND with earth motion, assuring protection from catastrophic failure associated with earthquakes and ground shock from nuclear blasts.


    • Interior storage of primary water supplies and septic systems (no water or septic tanks at or near ground level), assuring protection from ground slap associated with nuclear blast .
    • Steel air pipes and doors, assuring protection from wild fires, thermal pulse, high winds & flying objects.
    • Blast valves for all penetrations (Air pipes, Exhausts, Wiring, Antennas, etc.) assuring blast protection and continual positive air pressure in the event of chemical or biological attack.


  • Does the shelter provide adequate ventilation and air filtration capabilities?
    • Both electrical and manual (backup) functionality, assuring continual air supply in long term power failures.
    • Adequately sized air vents (4” – 6” diameter), assuring adequate supply of air and temperature control.
    • Metered air volume, assuring critical residence time within the high efficiency particulate (HEPA) filter when processing chemical and biological war gasses.
    • Pre-filters placed in line prior to processing of NBC contaminates, assuring protection of the HEPA filter from contaminates such as smoke, dirt, insects and larger radioactive particles.
    •  Ventilation and air filtration systems that have been tested and documented by a nationally recognized facility, assuring proper filter densities, air volumes, metering devices, blast protection, thickness of hose materials and metals and interior paints of the gas canister.

  • Can this shelter be customized to your needs (localized threat, water tightness, size, depth of cover, interior furnishings)?
    • Customized entrances and floor plans suited to your personal needs and desires.
    • Handicap entrances where needed.
    • Ample interior room for the storage of food, water and other supplies.
    • Sufficient volume to 'shut down' air supplies for 5 hours, during fires.

  • Has this shelter design been tested and approved by the Federal Government?
    • Will the manufacturer provide documentation of tests?
