THE S10 GUARD NBCE DISASTER SHELTER

The S10 GUARD is a fully rated underground bomb shelter with performance data, pressure and radiation ratings, and a 30-50 year structural warranty. It is a totally self-contained 10 psi NBCE underground shelter. The S10 GUARD underground disaster shelter is designed to protect 5 adults indefinitely using solar power. The product was specifically designed and developed to protect people during and after disasters such as tornadoes, hurricanes, earthquakes, storms, forest fires, power failures, nuclear power plant accidents, nuclear/chemical terrorism, HEMP attacks, and full-scale protracted nuclear, chemical and biological war. A tremendous effort has been made to think of every conceivable incident that shelterists could face in the S10 GUARD shelter. The shelter includes the steel hull and steel entranceway, cathodic corrosion protection system, ship stairwell, hatch, SEAM air filtration system, septic tank, floor, counter, fiberglass shower, 12- volt battery system, DC electrical system, AC electrical system, all wiring, all plumbing, etc. The generator and inverter/battery charger are protected by a tested EMP Shielded Enclosures. The S10 GUARD is shipped in two pieces, the shelter and the entranceway.

DESIGN Patent Pending

The S10 GUARD is an efficient shape for people to operate in. The space for humans inside is more than 98% useful with a floor span of 10 ft. with an 8 ft. ceiling. It is a fifth generation disaster shelter manufactured to standards of PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition, 2013, Brown Books, which is the United State’s bible on shelter engineering standards. It is known in the industry as P.O.P. The S10 GUARD was designed using CAD (computer aided drafting), CAE (computer aided engineering), and FEAM (3-dimensional finite element analysis and modeling). A shelterist in the S10 GUARD under heavy, direct effects from two 1-MT nuclear weapons, has at least the same probability of survival (99.7%) as a person living and working in peacetime. The structural shape of the S10 GUARD allows it to be a true pressure vessel for resistance to high external pressure. The S10 GUARD shelter system is based on 30+ years field experience with the Walton McCarthy’s successful P10, RC8 and CAT 25, and H10 Commander and H12 Admiral underground shelters.

SHELTER CONSTRUCTION

The 1,487 ft3 shelter hull is made of structural steel. The S10 GUARD hull is also epoxy dielectric coated all over the entire hull for superior corrosion resistance and connected to underground anodes. The entranceway is connected to the shelter hull through a seismic joint. The shelter is designed for 10 psi (pounds per square inch) external pressure resistance above the static earth load, without relying on earth arching. The floor is also smooth so it can be decontaminated since carpet is not allowed in an NBC shelter. All of these facilities function without outside electricity through the use solar panels charging a battery bank. The inside surface of the shelter hull is easily cleaned with common detergents and there is ample volume for food storage in the walls.

S10 Guard Bomb Shelter Exterior with Corrosion Protection AnodesCORROSION PROTECTION SYSTEM

The S10 GUARD hull exterior and interior are painted prior to shipping. The inside epoxy white coating has excellent flame and smoke properties. The exterior epoxy coating has strong dielectric properties and excellent cathodic bonding and abrasion resistance properties. Underground corrosion is an electrical process and the shelter hull corrosion is virtually stopped by the Cathodic Protection System. A typical galvanized culvert or tank hull erodes over time requiring the shelter hull pressure rating to be de-rated 2-5% each year. With the S10 GUARD Cathodic corrosion protection system, the underground anodes connected to the bottom of the shelter are much more electrically conductive than the shelter hull so the anodes electrically erode instead of the shelter hull. The corrosion protection system is monitored by a meter mounted on the shelter inside wall indicating that the corrosion protection system is operating and when the anodes needs to be replaced. The corrosion protection system allows support of a 30-50 year structural warranty.

SHELTER FACILITIES

The S10 GUARD contains 1,487 ft3 and 125 ft2 floor space with 8 ft. of headroom and 8 ft. high wall space. This allows relatively normal living and a very spacious feeling. There is ample light for reading anywhere in the shelter supplied by LED white lights. Fresh filtered air is brought into the shelter by a 12-volt air blower designed to operate 24 hours per day and supplies many times the breathing volume of air required by adults. This system has the advantage of maintaining constant shelter temperature, constant shelter oxygen levels, constant shelter carbon dioxide levels, and constant shelter moisture levels, plus it prevents overheating which is common with manual air blowers in warm climates. In addition, this electric blower air supply system works with all people including young children, people who are sick, people who are injured, people who are handicapped, and people who are elderly who may not be able to operate a manual blower system during a disaster. Exhausting of hot, moist, spent air is facilitated through the air ceiling exhaust to the air manifold at ground level. This is an efficient method of exhausting spent air, especially when resisting intruder assaults is a critical factor of the shelter design.

ELECTROMAGNETIC PULSE -EMP

NORAD shelters are designed to meet MIL-STD-188-125A:” High Altitude Electromagnetic Pulse (HEMP) Protection for Ground-Based C4I Facilities Performing Critical, Time-Urgent Missions Part 1: Fixed Facilities” 17 July 1998. All mission essential equipment (MEE) vulnerable to EMP is mounted in a tested aluminum EMP shielded enclosure. All NORAD shelters are self-contained and not connected to the electrical grid. The only MEE equipment in the S10 GUARD shelter that are vulnerable to EMP are the inverter/charger, generator, and generator/battery bank controls, which are all mounted in an aluminum EMP shielded enclosure. The EMP shielded enclosures meet QQ-A-200/8, MIL-C-7438, MIL-T-10727, and shielding minimums of MIL-188-125. The shelter system also includes a 2 ft3 EMP vault to store other electronic components in such as laptops, radios, TV’s, CD player etc. The golden rule for EMP protection in S10 Guard Bomb Shelter Cross Section Undergroundunderground shelters is, “DO NOT USE THE SHELTER HULL AS AN EMP SHIELD AND DO NOT USE THE EMP SHIELD AS A SHELTER”. The major problem in making underground shelters EMP safe, is dealing with all the POEs or “points of entry’ in underground shelter hulls that allow EMP to enter the shelter. Anything penetrating the hull such as entranceways, emergency escape tunnels, air inlet hoses, air outlet hoses, water hoses, electrical lines, and radio cables, etc., all need EMP shielded gaskets and/or EMP shielded air vents. Steel cannot usually be used as a Faraday Cage because it is not conductive enough. Electrical conductivity is measured in Siemens/meter (õ S/m). The minimum conductivity for a Faraday Cage to shield an EMP is 15,000,000 Siemens per meter. Steel has a conductivity of only 7,000,000 S/m so it is not conductive enough to effectively attenuate all EMP frequencies. Aluminum has a conductivity of 35,000,000 S/m and copper 60,000,000 S/m so both materials are very well suited for a Faraday Cage to effectively shield EMP. Bad welds, corroded welds, etc. in the shelter hull are all POEs making equipment in the shelter vulnerable to EMP. The NORAD approach to making an underground shelter EMP shielded, and a well accepted military practice, is to assume the shelter hull is EMP transparent and shield each individual unit vulnerable to EMP. The POEs in a shielded enclosure for a few cables are small and can be easily shielded. Also, unlike underground shelters, EMP shielded enclosures can be tested individually. Underground shelters with certified EMP shielded enclosures for MEE (Minimum Essential Equipment) meet the MIL-188-125A Standard. All of the NORAD shelter models, have been reviewed for an EMP Protection Analysis by a Certified Electromagnetic Compatibility Engineer and a Certified Electrostatic Discharge Control Engineer and found to comply with MIL-STD-188-125A with shielded enclosures for MEE.

The S10 GUARD SHELTER is an efficient shape for people to operate in and 98% useful with a floor span of 10 ft. whereas a 10 ft. diameter cylinder is only 60% useful with floor spans of approximately 7 ft. in order to provide adequate head room. It is a fifth generation disaster shelter manufactured to PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition, 2013, Brown Books, which is the United State’s bible on shelter engineering standards. It is known in the industry as P.O.P. The NORAD S10 GUARD was designed using CAD (computer aided drafting), CAE (computer aided engineering), and FEAM (3-dimensional finite element analysis and modeling). A shelterist in the S10 GUARD under heavy, direct effects from two 1-MT nuclear weapons, has at least the same probability of survival (99.7%) as a person living and working in peacetime. The structural shape and engineering of the S10 GUARD SHELTER allows it resist extreme pressure.

S10 Guard Bomb Shelter Floor Plan

SOLAR POWER

The S10 GUARD Shelter is supplied with a 2 KW solar system with an AGM battery bank. During peace time, a single 100 watt solar panel can maintain the battery bank. After an EMP event, the 100 watt solar panel is considered sacrificed and 8 new large solar panels that have been stored in the supplied EMP shielded enclosure, can be put in place to supply power indefinitely. Shelter durations are based on 16 – 24 hours/day operation of the TV, DVD player, computer, radios etc.

AC/DC INVERTER

Inverters convert DC power of the battery bank to 120 VAC power or house current. The inverter/charger is located inside an aluminum/nickel EMP shielded enclosure meeting QQ-A-200/8, MIL-C-7438, MIL-T-10727 and MIL-188-125 shielding.

S10 Guard Bomb Shelter Septic SystemSEPTIC SYSTEM

The S10 GUARD SHELTER is connected to a 1000 gallon septic tank (supplied) with a leach chamber system size based on the installation site percolation test. The septic system has an indefinite duration just like that of a conventional house.

S.E.A.M NBC AIR FILTRATION

Patent Pending

The Nuclear-Biological-Chemical or NBC S.E.A.M. is a “Bag-In/Bag Out” (BIBO) NBC air filtration system designed for long-term operation in severe NBC environments. The NBC filter housing is made of stainless steel. HEPA and carbon trays are able to be removed and replaced. The trays are replaced using a “bag in bag out” system so there is no human contact with the contaminated filter elements. On the front side of the filter housing is a vacuum dial gage which indicates when the filter is operating normally and when the filters need to be changed. In the case where the shelter is located near a nuclear air, ground, or surface burst detonation putting fallout into the atmosphere, any pre-filter or HEPA filter in any air filtration system located in the shelter will become too radioactive and dangerous to the shelterists to keep in the filter housing even though the vacuum gage may read normal. The level of radioactivity in the filter comes from radioactive contaminants in the pre-filter or HEPA filter tray which can be measured by a radiation meter by just standing in front of the access doors and holding the radiation meter at the center of the access cover. When the reading is above 1 rad/hr., the HEPA filter should be changed. Almost all of the initial fallout will have fallen in the first 24 hours so changing the HEPA filters should automatically be implemented after this period. Specific procedures are found in the S10 GUARD OPERATOR MANUAL for replacing filter elements.

The SEAM system for life support is located between the bed and the kitchen sink and supplies 100 cfm of fresh NBC filtered air and operates 24 hours per day. The air filtration system consists of three stages of air filtration. The first is a pre-filter which removes the radioactive and non-radioactive fine dust. The second stage is the ASZM TEDA carbon adsorber which removes the radioactive iodine gas and chemical warfare agents with the required residence time of 0.25+ seconds. The third stage is the HEPA filter which removes physical particles that are 0.3 microns and larger at 99.999% efficiency. The HEPA filter will trap the biological agents traveling on any air borne particles. For extended Sealed Shelter Atmosphere durations, a Lithium Hydroxide carbon scrubber tray can be used. One Lithium Hydroxide tray will remove enough carbon dioxide for ten people to stay in the shelter for approximately 24 hours. The stainless steel NBC filter housing has a gas agent test port to test for chemical agents using the supplied Chemical Agent Test Kit without leaving the shelter. A radiation survey meter and chemical agent test kit is also supplied.

Storage

The S10 GUARD has 110 lineal feet of shelving that is 11 inches wide and 18 inches high. There are 10 bays in the walls of the shelter hull. Each bay can store 8- 5 gallon buckets and 20 No. 10 cans plus toilet paper, clothing, tools, and other items. A key feature of the S10 GUARD is that it has enough floor space and efficient wall geometry to allow equipment, such as equipment and furniture, to be placed against the wall at the edge of the floor.

S10 Guard Bomb Shelter Air Manifold Patent PendingAIR MANIFOLDS

Air enters and exits the shelter through the air manifold assembly. The spent breathing air containing carbon dioxide, heat, moisture, and odors exits the shelter at the ceiling of the shelter at the opposite end to the SEAM air filtration system and exits to the atmosphere at ground level through the screened openings in the air manifold steel dome. Air enters the shelter through a separate air manifold assembly. The pipe flange at the bottom of the air manifold assembly is connected to a seismic joint which connects to the shelter hull to prevent shear damage during ground shock.

ENTRANCEWAY SEISMIC JOINT

The connection between the entranceway and the hull is made through a double axis seismic joint. This allows the entranceway to move independently without overstressing the hull end wall. The entranceway can be located within the frost line, while the shelter is well below the frost line. This creates tremendous stresses during winter months when the entranceway is forced up 0.5 – 1.25 inches due to frozen ground. The seismic joint removes these stresses by allowing vertical and lateral movement of the entranceway to maintain structural integrity during rolling ground motion from severe ground shock.

WATER SUPPLY

The S10 GUARD is designed to accept water from dedicated water well powered by the shelter power system, not powered on the local power grid, to prevent water pump damage from a HEMP weapon. There are also optional 2500 gallon underground water tanks which supplies a six month duration for 6 people.

S10 Guard Bomb Shelter Emergency Hatch (closed)STANDARD ENTRANCEWAY

The standard entranceway is a 60 deg. 36 inch diameter entranceway with a 30 in diameter clear opening, is usually used for emergency escape and is connected to the shelter though a seismic joint. The 30 inch diameter clear opening manhole allows large people to enter the shelter quickly. The hatch cover is spring loaded to open and requires approximately 10 lbs. of force to pull closed. The hatch can withstand 350 mph winds and has no surfaces exposed to projectiles.

The hatch is made of structural steel and can withstand a fire reaching 1700oF for one hour while maintaining its structural integrity in compliance to ASTM E119. Although the hatch is not impenetrable, it is specifically designed to resist seven basic assaults from people trying to break into the shelter in compliance to P.O.P.

S10 Guard Bomb Shelter Walk In Hatch (open)WALK IN ENTRANCEWAY 45 DEG.

The optional walk in entranceway is through a 72 inch diameter tunnel at a 45 degree angle connected to the shelter through a seismic joint. The flush steel hatch at ground level is aerodynamically smooth with a clear opening of 30 inches x 60 inches. There is nothing for flying debris to hit and the hatch can withstand 350 mph winds and is designed to protect the shelter from a fire reaching 1700oF for one hour while maintaining its structural integrity in compliance to ASTM E119.

HATCH EXTERIOR AND INTERIOR LOCK

The S10 GUARD hatch opens from the outside with a special mechanical key that cannot be made from a locksmith. When the shelter is unoccupied, a mechanical hasp and padlock is used. When the shelter is entered, the hasp and padlock are taken into the shelter. When inside the shelter, the hatch can be closed by turning a dog lever and inserting a locking pin. The hatch cover is designed to resist 5 psi negative pressure (5,000 lbs.) of uplifting force caused by the negative pressure of a tornado or explosion and 40 psi (20,000 lbs.) of overpressure. The average time it takes for untrained or inexperienced people to enter the shelter is approximately 5-10 seconds per person.

SHELTER DEFENSE

The S10 GUARD is not impenetrable but is difficult to break into while shelterists are inside.

INTRUDER ASSAULT HATCH AND AIR MANIFOLD RESISTANCE
1. Intruder trying to break into hatch using sledgehammer, hatchets, and guns. The steel hatch and air manifold resists hammer and hatchet assaults
2. Intruder trying to clog the air intake/outlet manifold to suffocate the shelterists thus forcing them outside. Shelterists can wait in safety in the shelter for many hours in sealed shelter atmosphere while the intruder is exposed to the outside danger.
3. Intruder trying to suffocate shelterists by creating a fire on top of the hatch or air manifold thus forcing the shelterists outside. The hatch and air manifold are resistant to fire up to 1700 F. and the shelterists can breathe normally inside the shelter based on sealed shelter atmosphere.
4. An intruder trying to run over the shelter or hatch with an automobile or truck. A vehicle running over the hatch or air manifold will still allow both to serve their function. If this vehicle becomes a threat, the Emergency Escape System can be used.
5. An intruder trying to drown shelterists by forcing water into the air inlet/out. The air inlet and outlet are baffled to prevent this type of assault.
6. An intruder trying to attach rope onto the hatch or air manifolds to damage or pull it out of ground. The hatch is a smooth design with no projections to easily attach to.
All attacks above Release of tear gas through hatch. Details are reviewed in Owner’s Manual.

S10 Guard Bomb Shelter Sealed Shelter AtmosphereSEALED SHELTER ATMOSPHERE

When ground fires are present around the hatch, the air blower should not be turned on to bring in fresh air. During this time, the shelterists must breathe in a sealed shelter atmosphere. The safe duration time is based on a 3% carbon dioxide limit. The time it takes for the shelter atmosphere to reach this limit is a function of the number of shelterists, degree of physical activity of the shelterists, and the volume of the shelter above the floor. Sealed Shelter Atmosphere graphs are provided for each specific shelter.

S10 Guard Bomb Shelter Blast ValvesINTERNAL PRESSURE CONTROL

The S10 GUARD uses 8 inch diameter stainless steel blast valves to prevent blast overpressure or underpressure from pressurizing the shelter injuring people. The valves are located inside the shelter where they can be easily serviced. These valves are normally open and close from blast overpressure or negative pressure maintaining the normal shelter atmosphere. The air inlet and outlet openings are also sized to allow overpressure choking as a redundant system. Blast valves are located inside the shelter directly above the SEAM air filtration unit and on the air outlet on the ceiling.

PLUMBING SYSTEM

Water Filter-The shelter is equipped with a sub-micron water filter for all water used at the sink, shower, and toilet. Two of the batteries will supply enough power to pump approximately 1000 gallons of filtered water from the tank or water well. The counter contains a large stainless steel utility sink where dishes, clothes, and pets are washed. The sink, shower, and toilet, drain into a sewage lift station which transfers sewage up to a high pressure septic system. The bath room is under negative pressure 24 hours per day venting all spent air and odors to the ceiling air outlet connected to the air manifold at the ground surface.

Fittings– The shelter entranceway contains NPTF thru-hull couplings below ground level, for plumbing and electrical connection to the water tank or well and bringing in antenna lines or a phone line.

Toilet– The toilet used is a conventional flush toilet draining into the sewage lift station under the shelter floor. The sewage is pumped up to the septic tank through an internal and external hose.

Shower– The one piece fiberglass shower stall allows all water from the shower head to drain into the sewage lift station. NBC decontamination is performed in this shower using the supplied decontamination solution and spray bottle.

Cooking –The S10 uses an alcohol cooking stove and includes 10 gallons of methanol.

RADIATION SHIELDING

The protection factor (PF) of a shelter is the ratio of a radiation dose over smooth ground which would be received by an unprotected person, compared to the dose that would be received by a person in a sheltered location. For example, a PF of 40 means that a person would receive l/40th the radiation in a shelter compared to the radiation that he would receive unprotected. A PF of l00 = l/100th. This is the fraction of radiation that a shelterist would receive from overhead (not accounting for radiation entered through the entranceway). The PF alone should never be used to determine the radiation entering a blast shelter. The Half Value Layer Thickness (HVL) is the material thickness required to reduce the radiation dose to half. Earth has an HVL of 5.5 inches and concrete has an HVL of 4.7 inches will reduce the radiation dose to half.

Radiation shielding from overhead in the S10 GUARD is provided by 72 inches of earth at the crown of the shelter ceiling. With a TRS (Total Rems in Shelter at the shelter entrance) of 5 rems at 10 psi (0.6 miles from GZ of a 100 KT weapon), the shelterist would be safe. This 30 day dose is based on a 100 KT surface burst to maximize radiation fallout. (See of PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition, 737 pp, 2013). A shelters’s radiation dose must always be related to the shelter’s overpressure rating.

Based on the worst cancer cases (leukemia) from the Hiroshima and Nagasaki victims, a 10-rem dose may increase the cancer rates from the current rate of 352/100,000 up to 355/100,000. It should be kept in mind that the Hiroshima victims were totally unprepared and uneducated. They were malnourished and already suffering from many diseases during a critical wartime period where food, medical supplies, and other necessities were in short supply. In addition, they were not only exposed to heavy, acute external radiation doses but also internal radiation doses from eating contaminated food and inhaling radioactive fallout. Educated shelterists can avoid such damaging effects and can determine the radiation levels with a simple radiation survey meter supplied with the S10 GUARD along with a chemical agent detection kit.

Emergency Escape

In the event that heavy debris falls on the hatch cover and the radios are not able to bring help to clear the hatch, emergency escape procedures can be implemented. The S10 GUARD uses a manually operated mechanical jack to force the hatch open. The 18 inch long handle will require 50 lbs. downward force to generate 8,000 pounds of uplifting force.

INSTALLATION RIGHTS

U.S. citizens have a legal right to install an underground shelter. Under the second amendment of the United States Constitution, U.S. citizens are guaranteed the right to bear arms to provide protection in life threatening situations. In 2006, FEMA released the National Planning Scenarios listing nuclear, biological, and chemical weapons as credible disasters that federal, state, and local municipalities should develop a preparedness plan for. A disaster shelter falls under this classification as a defensive arm against natural and man-made disasters listed in this government report. The NORAD shelters are considered a temporary and emergency structure that can be redeployed to another location. Denying a permit for such a life saving device such as a shelter is a violation of civil rights and local government officials are NOT protected by sovereign immunity that they normally operate under and each building official is personally liable. A Civil Right’s Attorney is used by the customer in any legal conflict.

  THE S10 NOMAD BOMB SHELTER

The S10 NOMAD is a fully rated underground shelter with performance data, pressure and radiation ratings, and a 30-50 year structural warranty. It is a totally self-contained 10 psi NBCE underground shelter. The S10 NOMAD underground disaster shelter is designed to protect 6 adults indefinitely from solar power. The product was specifically designed and developed to protect people during and after disasters such as tornadoes, hurricanes, earthquakes, storms, forest fires, power failures, nuclear power plant accidents, nuclear/chemical terrorism, HEMP attacks, and full-scale protracted nuclear, chemical and biological war. A tremendous effort has been made to think of every conceivable incident that shelterists could face in the S10 NOMAD shelter. The shelter includes the steel hull and steel entranceway, cathodic corrosion protection system, ship stairwell, hatch, SEAM air filtration system, septic tank, floor, counter, fiberglass shower, 12- volt battery system, DC electrical system, AC electrical system, all wiring, all plumbing, etc. The generator and inverter/battery charger are protected by a tested EMP Shielded Enclosures. The S10 NOMAD is shipped in two pieces, the shelter and the entranceway.

DESIGN Patent Pending

The S10 NOMAD is an efficient shape for people to operate in. The space for humans inside is more than 98% useful with a floor span of 10 ft. with an 8 ft. ceiling. It is a fifth generation disaster shelter manufactured to standards of PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition, 2013, Brown Books, which is the United State’s bible on shelter engineering standards. It is known in the industry as P.O.P. The S10 NOMAD was designed using CAD (computer aided drafting), CAE (computer aided engineering), and FEAM (3-dimensional finite element analysis and modeling). A shelterist in the S10 NOMAD under heavy, direct effects from two 1-MT nuclear weapons, has at least the same probability of survival (99.7%) as a person living and working in peace-time. The structural shape of the S10 NOMAD allows it to be a true pressure vessel for resistance to high external pressure. The S10 NOMAD shelter system is based on 30+ years field experience with the Walton McCarthy’s successful P10, RC8 and CAT 25, and H10 Commander and H12 Admiral underground shelters.

CIVILIAN SHELTER

The S10 NOMAD is a solar-powered civilian shelter. NORAD does not make an S10 NOMAD military model.

SHELTER CONSTRUCTION

The 2,230 ft3 shelter hull is made of structural steel. The S10 NOMAD hull is also epoxy dielectric coated all over the entire hull for superior corrosion resistance and connected to underground anodes. The entranceway is connected to the shelter hull through a seismic joint. The shelter is designed for 10 psi (pounds per square inch) external pressure resistance above the static earth load, without relying on earth arching. The floor is also smooth so it can be decontaminated since carpet is not allowed in an NBC shelter. All of these facilities function without outside electricity through the use solar panels charging a battery bank. The inside surface of the shelter hull is easily cleaned with common detergents and there is ample volume for food storage in the walls.

S10 Nomad Bomb Shelter Corrosion Protection

CORROSION PROTECTION SYSTEM

The S10 NOMAD hull exterior and interior are painted prior to shipping. The inside epoxy white coating has excellent flame and smoke properties. The exterior epoxy coating has strong dielectric properties and excellent cathodic bonding and abrasion resistance properties. Underground corrosion is an electrical process and the shelter hull corrosion is virtually stopped by the Cathodic Protection System. A typical galvanized culvert or tank hull erodes over time requiring the shelter hull pressure rating to be de-rated 2-5% each year. With the S10 NOMAD Cathodic corrosion protection system, the underground anodes connected to the bottom of the shelter are much more electrically conductive than the shelter hull so the anodes electrically erode instead of the shelter hull. The corrosion protection system is monitored by a meter mounted on the shelter inside wall indicating that the corrosion protection system is operating and when the anodes needs to be replaced. The corrosion protection system allows support of a 30-50 year structural warranty.

SHELTER FACILITIES

The S10 NOMAD contains 2,330 ft3 and 205 ft2 floor space with 8 ft. of headroom and 8 ft. high wall space. This allows relatively normal living and a very spacious feeling. There is ample light for reading anywhere in the shelter supplied by LED white lights. Fresh filtered air is brought into the shelter by a 12-volt air blower designed to operate 24 hours per day and supplies many times the breathing volume of air required by adults. This system has the advantage of maintaining constant shelter temperature, constant shelter oxygen levels, constant shelter carbon dioxide levels, and constant shelter moisture levels, plus it prevents overheating which is common with manual air blowers in warm climates. In addition, this electric blower air supply system works with all people including young children, people who are sick, people who are injured, people who are handicapped, and people who are elderly who may not be able to operate a manual blower system during a disaster. Exhausting of hot, moist, spent air is facilitated through the air ceiling exhaust to the air manifold at ground level. This is an efficient method of exhausting spent air, especially when resisting intruder assaults is a critical factor of the shelter design.

ELECTROMAGNETIC PULSE -EMP

NORAD shelters are designed to meet MIL-STD-188-125A:” High Altitude Electromagnetic Pulse (HEMP) Protection for Ground-Based C4I Facilities Performing Critical, Time-Urgent Missions Part 1: Fixed Facilities” 17 July 1998. All mission essential equipment (MEE) vulnerable to EMP is mounted in a tested aluminum EMP shielded enclosure. All NORAD shelters are self-contained and not connected to the electrical grid. The only MEE equipment in the S10 NOMAD shelter that are vulnerable to EMP are the inverter/charger, generator, and generator/battery bank controls, which are all mounted in an aluminum EMP shielded enclosure. The EMP shielded enclosures meet QQ-A-200/8, MIL-C-7438, MIL-T-10727, and shielding minimums of MIL-188-125. The shelter system also includes a 2 ft3 EMP vault to store other electronic components in such as laptops, radios, TV’s, CD player etc. The golden rule for EMP protection in underground shelters is, “DO NOT USE THE SHELTER HULL AS AN EMP SHIELD AND DO NOT USE THE EMP SHIELD AS A SHELTER”. The major problem in making underground shelters EMP safe, is dealing with all the POEs or “points of entry’ in underground shelter hulls that allow EMP to enter the shelter. Anything penetrating the hull such as entranceways, emergency escape tunnels, air inlet hoses, air outlet hoses, water hoses, electrical lines, and radio cables, etc., all need EMP shielded gaskets and/or EMP shielded air vents. Steel cannot usually be used as a Faraday Cage because it is not conductive enough. Electrical conductivity is measured in Siemens/meter (õ S/m). The minimum conductivity for a Faraday Cage to shield an EMP is 15,000,000 Siemens per meter. Steel has a conductivity of only 7,000,000 S/m so it is not conductive enough to effectively attenuate all EMP frequencies. Aluminum has a conductivity of 35,000,000 S/m and copper 60,000,000 S/m so both materials are very well suited for a Faraday Cage to effectively shield EMP. Bad welds, corroded welds, etc. in the shelter hull are all POEs making equipment in the shelter vulnerable to EMP. The NORAD approach to making an underground shelter EMP shielded, and a well accepted military practice, is to assume the shelter hull is EMP transparent and shield each individual unit vulnerable to EMP. The POEs in a shielded enclosure for a few cables are small and can be easily shielded. Also, unlike underground shelters, EMP shielded enclosures can be tested individually. Underground shelters with certified EMP shielded enclosures for MEE (Minimum Essential Equipment) meet the MIL-188-125A Standard. All of the NORAD shelter models, have been reviewed for an EMP Protection Analysis by a Certified Electromagnetic Compatibility Engineer and a Certified Electrostatic Discharge Control Engineer and found to comply with MIL-STD-188-125A with shielded enclosures for MEE. The S10 NOMAD SHELTER is an efficient shape for people to operate in and 98% useful with a floor span of 10 ft. whereas a 10 ft. diameter cylinder is only 60% useful with floor spans of approximately 7 ft. in order to provide adequate head room. It is a fifth generation disaster shelter manufactured to PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition, 2013, Brown Books, which is the United State’s bible on shelter engineering standards. It is known in the industry as P.O.P. The NORAD S10 NOMAD was designed using CAD (computer aided drafting), CAE (computer aided engineering), and FEAM (3-dimensional finite element analysis and modeling). A shelterist in the S10 NOMAD under heavy, direct effects from two 1-MT nuclear weapons, has at least the same probability of survival (99.7%) as a person living and working in peace­time. The structural shape and engineering of the S10 NOMAD SHELTER allows it resist extreme pressure. S10 Nomad Shelter Floor Plan

S10 Nomad Bomb Shelter Under 6 ft. earth

SOLAR POWER

The S10 NOMAD Shelter is supplied with a 2 KW solar system with an AGM battery bank. During peace time, a single 100 watt solar panel can maintain the battery bank. After an EMP event, the 100 watt solar panel is considered sacrificed and 8 new large solar panels that have been stored in the supplied EMP shielded enclosure, can be put in place to supply power indefinitely. Shelter durations are based on 16 – 24 hours/day operation of the TV, DVD player, computer, radios etc.

AC/DC INVERTER

Inverters convert DC power of the battery bank to 120 VAC power or house current. The inverter/charger is located inside an aluminum/nickel EMP shielded enclosure meeting QQ-A-200/8, MIL-C-7438, MIL-T-10727 and MIL-188-125 shielding.

S10 Nomad Bomb Shelter SepticSEPTIC SYSTEM

The S10 NOMAD SHELTER is connected to a 1000 gallon septic tank (supplied) with a leach chamber system size based on the installation site percolation test. The septic system has an indefinite duration just like that of a conventional house.

S.E.A.M NBC AIR FILTRATION

Patent Pending The Nuclear-Biological-Chemical or NBC S.E.A.M. is a “Bag-In/Bag Out” (BIBO) NBC air filtration system designed for long-term operation in severe NBC environments. The NBC filter housing is made of stainless steel. HEPA and carbon trays are able to be removed and replaced. The trays are replaced using a “bag in bag out” system so there is no human contact with the contaminated filter elements. On the front side of the filter housing is a vacuum dial gage which indicates when the filter is operating normally and when the filters need to be changed. In the case where the shelter is located near a nuclear air, ground, or surface burst detonation putting fallout into the atmosphere, any pre-filter or HEPA filter in any air filtration system located in the shelter will become too radioactive and dangerous to the shelterists to keep in the filter housing even though the vacuum gage may read normal. The level of radioactivity in the filter comes from radioactive contaminants in the pre-filter or HEPA filter tray which can be measured by a radiation meter by just standing in front of the access doors and holding the radiation meter at the center of the access cover. When the reading is above 1 rad/hr., the HEPA filter should be changed. Almost all of the initial fallout will have fallen in the first 24 hours so changing the HEPA filters should automatically be implemented after this period. Specific procedures are found in the S10 NOMAD OPERATOR MANUAL for replacing filter elements. The SEAM system for life support is located near the end wall of the shelter and supplies 100 cfm of fresh NBC filtered air and operates 24 hours per day. The air filtration system consists of three stages of air filtration. The first is a pre-filter which removes the radioactive and non-radioactive fine dust. The second stage is the ASZM TEDA carbon adsorber which removes the radioactive iodine gas and chemical warfare agents with the required residence time of 0.25+ seconds. The third stage is the HEPA filter which removes physical particles that are 0.3 microns and larger at 99.999% efficiency. The HEPA filter will trap the biological agents traveling on any air borne particles. For extended Sealed Shelter Atmosphere durations, a Lithium Hydroxide carbon scrubber tray can be used. One Lithium Hydroxide tray will remove enough carbon dioxide for ten people to stay in the shelter for approximately 24 hours. The stainless steel NBC filter housing has a gas agent test port to test for chemical agents using the supplied Chemical Agent Test Kit with leaving the shelter. A radiation survey meter and chemical agent test kit is also supplied.

STORAGE

The S10 NOMAD has 170 lineal feet of shelving that is 11 inches wide and 18 inches high. There are 20 bays in the walls of the shelter hull. Each bay can store ten 5 gallon buckets and 20 No. 10 cans plus toilet paper, clothing, tools, and other items. A key feature of the S10 NOMAD is that it has enough floor space and efficient wall geometry to allow equipment, such as equipment and furniture, to be placed against the wall at the edge of the floor.

S10 Nomad Shelter Air Manifold Patent PendingAIR MANIFOLDS

Air enters and exits the shelter through the air manifold assembly. The spent breathing air containing carbon dioxide, heat, moisture, and odors exits the shelter at the ceiling of the shelter at the opposite end to the SEAM air filtration system and exits to the atmosphere at ground level through the screened openings in the air manifold steel dome. Air enters the shelter through a separate air manifold assembly. The pipe flange at the bottom of the air manifold assembly is connected to a seismic joint which connects to the shelter hull to prevent shear damage during ground shock.

ENTRANCEWAY SEISMIC JOINT

The connection between the entranceway and the hull is made through a double axis seismic joint. This allows the entranceway to move independently without overstressing the hull end wall. The entranceway can be located within the frost line, while the shelter is well below the frost line. This creates tremendous stresses during winter months when the entranceway is forced up 0.5 – 1.25 inches due to frozen ground. The seismic joint removes these stresses by allowing vertical and lateral movement of the entranceway to maintain structural integrity during rolling ground motion from severe ground shock.

WATER SUPPLY

The S10 NOMAD is designed to accept water from dedicated water well powered by the shelter power system, not powered on the local power grid, to prevent water pump damage from a HEMP weapon. A backup water pump can be kept in the shelter in the EMP vault. There are also optional 2500 gallon underground water tanks which supplies a six month duration for 6 people.
S10 Nomad Bomb Shelter Hatch Closed S10 Nomad Bomb Shelter Hatch Open

STANDARD ENTRANCEWAY

the standard entranceway is a 60 deg. 36 inch diameter entranceway with a 30 in diameter clear opening, is usually used for emergency escape and is connected to the shelter though a seismic joint. The 30 inch diameter clear opening manhole allows large people to enter the shelter quickly. The hatch cover is spring loaded to open and requires approximately 10 lbs. of force to pull closed. The hatch can withstand 350 mph winds and has no surfaces exposed to projectiles. The hatch is made of structural steel and can withstand a fire reaching 1700oF for one hour while maintaining its structural integrity in compliance to ASTM E119. Although the hatch is not impenetrable, it is specifically designed to resist seven basic assaults from people trying to break into the shelter in compliance to P.O.P.

S10 Nomad Bomb Shelter Walkin EntranceWALK IN ENTRANCEWAY 45 DEG.

The optional walk in entranceway is through a 72 inch diameter tunnel at a 45 degree angle connected to the shelter through a seismic joint. The flush steel hatch at ground level is aerodynamically smooth with a clear opening of 30 inches x 60 inches. There is nothing for flying debris to hit and the hatch can withstand 350 mph winds and is designed to protect the shelter from a fire reaching 1700oF for one hour while maintaining its structural integrity in compliance to ASTM E119.

HATCH EXTERIOR AND INTERIOR LOCK

The S10 NOMAD hatch opens from the outside with a special mechanical key that cannot be made from a locksmith. When the shelter is unoccupied, a mechanical hasp and padlock is used. When the shelter is entered, the hasp and padlock are taken into the shelter. When inside the shelter, the hatch can be closed by turning a dog lever and inserting a locking pin. The hatch cover is designed to resist 5 psi negative pressure (5,000 lbs.) of uplifting force caused by the negative pressure of a tornado or explosion and 40 psi (20,000 lbs.) of overpressure. The average time it takes for untrained or inexperienced people to enter the shelter is approximately 5-10 seconds per person.

SHELTER DEFENSE

The S10 NOMAD is not impenetrable but is difficult to break into while shelterists are inside.

INTRUDER ASSAULT HATCH AND AIR MANIFOLD RESISTANCE
1. Intruder trying to break into hatch using sledgehammer, hatchets, and guns. The steel hatch and air manifold resists hammer and hatchet assaults
2. Intruder trying to clog the air intake/outlet manifold to suffocate the shelterists thus forcing them outside. Shelterists can wait in safety in the shelter for many hours in sealed shelter atmosphere while the intruder is exposed to the outside danger.
3. Intruder trying to suffocate shelterists by creating a fire on top of the hatch or air manifold thus forcing the shelterists outside. The hatch and air manifold are resistant to fire up to 1700 F. and the shelterists can breathe normally inside the shelter based on sealed shelter atmosphere.
4. An intruder trying to run over the shelter or hatch with an automobile or truck. A vehicle running over the hatch or air manifold will still allow both to serve their function. If this vehicle becomes a threat, the Emergency Escape System can be used.
5. An intruder trying to drown shelterists by forcing water into the air inlet/out. The air inlet and outlet are baffled to prevent this type of assault.
6. An intruder trying to attach rope onto the hatch or air manifolds to damage or pull it out of ground. The hatch is a smooth design with no projections to easily attach to.
All attacks above Release of tear gas through hatch. Details are reviewed in Owner’s Manual.

S10 Nomad Bomb Shelter Sealed Atmosphere

SEALED SHELTER ATMOSPHERE

When ground fires are present around the hatch, the air blower should not be turned on to bring in fresh air. During this time, the shelterists must breathe in a sealed shelter atmosphere. The safe duration time is based on a 3% carbon dioxide limit. The time it takes for the shelter atmosphere to reach this limit is a function of the number of shelterists, degree of physical activity of the shelterists, and the volume of the shelter above the floor. Sealed Shelter Atmosphere graphs are provided for each specific shelter.

INTERNAL PRESSURE CONTROL

S10 Nomad Shelter Blast ValvesThe S10 NOMAD uses 8 inch diameter stainless steel blast valves to prevent blast overpressure or underpressure from pressurizing the shelter injuring people. The valves are located inside the shelter where they can be easily serviced. These valves are normally open and close from blast overpressure or negative pressure maintaining the normal shelter atmosphere. The air inlet and outlet openings are also sized to allow overpressure choking as a redundant system. Blast valves are located inside the shelter directly above the SEAM air filtration unit and on the air outlet on the ceiling.

PLUMBING SYSTEM

Water Filter-The shelter is equipped with a sub-micron water filter for all water used at the sink, shower, and toilet. Two of the batteries will supply enough power to pump approximately 1000 gallons of filtered water from the tank or water well. The counter contains a large stainless steel utility sink where dishes, clothes, and pets are washed. The sink, shower, and toilet, drain into a sewage lift station which transfers sewage up to a high pressure septic system. The bath room is under negative pressure 24 hours per day venting all spent air and odors to the ceiling air outlet connected to the air manifold at the ground surface. Fittings– The shelter entranceway contains NPTF thru-hull couplings below ground level, for plumbing and electrical connection to the water tank or well and bringing in antenna lines or a phone line. Toilet– The toilet used is a conventional flush toilet draining into the sewage lift station under the shelter floor. The sewage is pumped up to the septic tank through an internal and external hose. Shower– The one piece fiberglass shower stall allows all water from the shower head to drain into the sewage lift station. NBC decontamination is performed in this shower using the supplied decontamination solution and spray bottle. Cooking –The S10 uses an alcohol cooking stove and includes 10 gallons of methanol.

RADIATION SHIELDING

The protection factor (PF) of a shelter is the ratio of a radiation dose over smooth ground which would be received by an unprotected person, compared to the dose that would be received by a person in a sheltered location. For example, a PF of 40 means that a person would receive l/40th the radiation in a shelter compared to the radiation that he would receive unprotected. A PF of l00 = l/100th. This is the fraction of radiation that a shelterist would receive from overhead (not accounting for radiation entered through the entranceway). The PF alone should never be used to determine the radiation entering a blast shelter. The Half Value Layer Thickness (HVL) is the material thickness required to reduce the radiation dose to half. Earth has an HVL of 5.5 inches and concrete has an HVL of 4.7 inches will reduce the radiation dose to half. Radiation shielding from overhead in the S10 NOMAD is provided by 72 inches of earth at the crown of the shelter ceiling. With a TRS (Total Rems in Shelter at the shelter entrance) of 5 rems at 10 psi (0.6 miles from GZ of a 100 KT weapon), the shelterist would be safe. This 30 day dose is based on a 100 KT surface burst to maximize radiation fallout. (See of PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition, 737 pp, 2013). A shelters’s radiation dose must always be related to the shelter’s overpressure rating. Based on the worst cancer cases (leukemia) from the Hiroshima and Nagasaki victims, a 10-rem dose may increase the cancer rates from the current rate of 352/100,000 up to 355/100,000. It should be kept in mind that the Hiroshima victims were totally unprepared and uneducated. They were malnourished and already suffering from many diseases during a critical wartime period where food, medical supplies, and other necessities were in short supply. In addition, they were not only exposed to heavy, acute external radiation doses but also internal radiation doses from eating contaminated food and inhaling radioactive fallout. Educated shelterists can avoid such damaging effects and can determine the radiation levels with a simple radiation survey meter supplied with the S10 NOMAD along with a chemical agent detection kit.

EMERGENCY ESCAPE

In the event that heavy debris falls on the hatch cover and the radios are not able to bring help to clear the hatch, emergency escape procedures can be implemented. The S10 NOMAD uses a manually operated mechanical jack to force the hatch open. The 18 inch long handle will require 50 lbs. downward force to generate 8,000 pounds of uplifting force.

INSTALLATION RIGHTS

U.S. citizens have a legal right to install an underground shelter. Under the second amendment of the United States Constitution, U.S. citizens are guaranteed the right to bear arms to provide protection in life threatening situations. In 2006, FEMA released the National Planning Scenarios listing nuclear, biological, and chemical weapons as credible disasters that federal, state, and local municipalities should develop a preparedness plan for. A disaster shelter falls under this classification as a defensive arm against natural and man-made disasters listed in this government report. The NORAD shelters are considered a temporary and emergency structure that can be redeployed to another location. Denying a permit for such a life saving device such as a shelter is a violation of civil rights and local government officials are NOT protected by sovereign immunity that they normally operate under and each building official is personally liable. A Civil Right’s Attorney is used by the customer in any legal conflict.

THE S10 OUTPOST BOMB SHELTER

The S10 Outpost bomb shelter is a fully rated underground shelter with performance data, pressure and radiation ratings, and a 30-50 year warranty. It is a totally self-contained 10 psi NBCE underground shelter. The S10 Outpost underground disaster shelter is designed to protect 8-12 adults for almost 1 year off-grid. The product was specifically designed and developed to protect people during and after disasters such as tornadoes, hurricanes, earthquakes, storms, forest fires, power failures, nuclear power plant accidents, nuclear/chemical terrorism, EMP attacks, and full-scale protracted nuclear, chemical and biological war. A tremendous effort has been made to think of every conceivable incident that shelterists could face in the S10 Outpost shelter. The S10 Outpost includes the steel hull and steel entranceway, cathodic corrosion protection system, ship stairwell, hatch, SEAM air filtration system, septic tank, floor, counter, fiberglass shower, 12- volt battery system, DC electrical system, AC electrical system, all wiring, and all plumbing. Tested EMP-shielded enclosures protect the generator and inverter/battery charger. The S10 OUTPOST is shipped in two pieces: the shelter and the entranceway.

THE S10 OUTPOST IS A MILITARY SHELTER

The S10x40 is available only as a military model (S10x40-MIL) supplied with a 6.5KW internal EMP-shielded diesel generator. We do not make a civilian S10x40 bomb shelter with solar power.

DESIGN Patent Pending

The S10 Outpost bomb shelter is an efficient shape for people to operate in. The space for humans inside is more than 98% useful. The floor is 10 ft. wide and the ceiling is 8 ft. high. The S10 Outpost is a fifth generation disaster shelter manufactured to standards of PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition, 2013, Brown Books, which is the United State’s bible on shelter engineering standards. It is known in the industry as P.O.P. The S10 Outpost was designed using CAD (computer aided drafting), CAE (computer aided engineering), and FEAM (3-dimensional finite element analysis and modeling). A shelterist in the S10 Outpost under heavy, direct effects from two 1-MT nuclear weapons, has at least the same probability of survival (99.7%) as a person living and working in peacetime. The structural shape of the S10 Outpost allows it to be a true pressure vessel for resistance to high external pressure. The S10 Outpost shelter system is based on 30+ years field experience with Walton McCarthy’s successful P10, RC8 and CAT 25, and H10 Commander and H12 Admiral underground shelters.

S10x40 Triple Configuration Underground Shelters

SHELTER CONSTRUCTION

The 4,300 ft3 shelter hull is made of structural steel. The entranceway is connected to the shelter hull through a seismic joint. The shelter is designed for 10 psi (pounds per square inch) external pressure resistance above the static earth load, without relying on earth arching. The floor is also smooth so it can be decontaminated since carpet is not allowed in an NBC shelter. All of these facilities function without outside electricity through the use of an internal EMP shielded diesel generator  charging a battery bank. The inside surface of the shelter hull is easily cleaned with common detergents and there is ample volume for food storage in the walls.

CORROSION PROTECTION SYSTEM

The S10 Outpost hull is both coated with dielectric epoxy over its entire hull and is connected to sacrificial anodes for superior corrosion resistance. The inside epoxy white coating has excellent flame and smoke properties. The exterior epoxy coating has strong dielectric properties and excellent cathodic bonding and abrasion resistance properties. Underground corrosion is an electrical process and the shelter hull corrosion is virtually stopped by the Cathodic Protection System. A typical galvanized culvert or tank hull erodes over time requiring the shelter hull pressure rating to be de-rated 2-5% each year. With the NORAD S10 Outpost cathodic corrosion protection system, the underground anodes connected to the bottom of the shelter are much more electrically conductive than the shelter hull so the anodes electrically erode instead of the shelter hull. The corrosion protection system is monitored by a meter mounted on the shelter inside wall indicating that the corrosion protection system is operating and when the anodes needs to be replaced. The corrosion protection system allows support of a 30-50 year structural warranty.

S10 Outpost Bomb Shelter Corrosion Protection System

SHELTER FACILITIES

The S10 Outpost contains 4,300 ft3 and 387 ft2 floor space with 8 ft. of headroom and 8 ft. high wall space. This allows relatively normal living and a very spacious feeling. There is ample light for reading anywhere in the shelter supplied by LED white lights. Fresh filtered air is brought into the shelter by a 12-volt air blower designed to operate 24 hours per day and supplies many times the breathing volume of air required by adults. This system has the advantage of maintaining constant shelter temperature, constant shelter oxygen levels, constant shelter carbon dioxide levels, and constant shelter moisture levels, plus it prevents overheating which is common with manual air blowers in warm climates. In addition, this electric blower air supply system works with all people including young children, people who are sick, people who are injured, people who are handicapped, and people who are elderly who may not be able to operate a manual blower system during a disaster. Exhausting of hot, moist, spent air is facilitated through the air ceiling exhaust to the air manifold at ground level. This is an efficient method of exhausting spent air, especially when resisting intruder assaults is a critical factor of the shelter design.

ELECTROMAGNETIC PULSE -EMP

NORAD shelters are designed to meet MIL-STD-188-125A:” High Altitude Electromagnetic Pulse (HEMP) Protection for Ground-Based C4I Facilities Performing Critical, Time-Urgent Missions Part 1: Fixed Facilities” 17 July 1998. All mission essential equipment (MEE) vulnerable to EMP is mounted in a tested aluminum EMP shielded enclosure. All NORAD shelters are self-contained and not connected to the electrical grid. The only MEE equipment in the S10 Outpost shelter that are vulnerable to EMP are the inverter/charger, generator, and generator/battery bank controls, which are all mounted in an aluminum EMP shielded enclosure. The EMP shielded enclosures meet QQ-A-200/8, MIL-C-7438, MIL-T-10727, and shielding minimums of MIL-188-125. The shelter system also includes a 2 ft3 EMP vault to store other electronic components such as laptops, radios, TV’s, CD player etc.

The golden rule for EMP protection in underground shelters is: “DO NOT USE THE SHELTER HULL AS AN EMP SHIELD AND DO NOT USE THE EMP SHIELD AS A SHELTER.” The major problem in making underground shelters EMP safe, is dealing with all the POEs or “points of entry’ in underground shelter hulls that allow EMP to enter the shelter. Anything penetrating the hull such as entranceways, emergency escape tunnels, air inlet hoses, air outlet hoses, water hoses, electrical lines, and radio cables, etc., all need EMP shielded gaskets and/or EMP shielded air vents. Steel cannot usually be used as a Faraday Cage because it is not conductive enough. Electrical conductivity is measured in Siemens/meter (õ S/m). The minimum conductivity for a Faraday Cage to shield an EMP is 15,000,000 Siemens per meter. Steel has a conductivity of only 7,000,000 S/m so it is not conductive enough to effectively attenuate all EMP frequencies. Aluminum has a conductivity of 35,000,000 S/m and copper 60,000,000 S/m so both materials are very well suited for a Faraday Cage to effectively shield EMP. Bad welds, corroded welds, etc. in the shelter hull are all POEs making equipment in the shelter vulnerable to EMP. The NORAD approach to making an underground shelter EMP shielded, and a well accepted military practice, is to assume the shelter hull is EMP transparent and shield each individual unit vulnerable to EMP. The POEs in a shielded enclosure for a few cables are small and can be easily shielded. Also, unlike underground shelters, EMP shielded enclosures can be tested individually. Underground shelters with certified EMP shielded enclosures for MEE (Minimum Essential Equipment) meet the MIL-188-125A Standard. All of the NORAD shelter models, have been reviewed for an EMP Protection Analysis by a Certified Electromagnetic Compatibility Engineer and a Certified Electrostatic Discharge Control Engineer and found to comply with MIL-STD-188-125A with shielded enclosures for MEE.

DIESEL GENERATOR POWER

The S10 Outpost bomb shelter  is supplied with an internal 6.5 KW diesel generator located in a sealed and pressurized room connected to a 400 gallon aluminum diesel tank. The tank is serviced by a circulating pump, filter and fill port to accept fuel, emulsifiers, and fungicides. The generator is housed in an aluminum/nickel EMP shielded enclosure meeting QQ-A-200/8, MIL-C-7438, MIL-T-10727 and MIL-188-125 EMP shielding and is an isolated enclosure. The generator enclosure is vented through the shelter ceiling. The generator room is a separate room pressurized with NBC filtered air. This generator’s power can also be used to power another structure such as a nearby house. Shelter durations shown below are based on 16 to 24 hours/day operation of the TV, DVD player, computer, radios etc. The S10-MIL has three circuit breaker panels: One for the 12 volt DC system, one for the inverter AC, and one for the generator AC.

SEPTIC SYSTEM

The S10 Outpost shelter is connected to a 1000 gallon septic tank (supplied) with a leach chamber system size based on the installation site percolation test. The septic system has an indefinite duration just like that of one found in a conventional house.

S.E.A.M NBC AIR FILTRATION

Patent Pending
The NORAD S10 Outpost has two modern air filtration systems called SEAM units. (Severe Environment Air Module). One SEAM unit is dedicated to the supplying cooling and combustion air to the generator and one SEAM unit is dedicated to the breathing air for life support. Each SEAM unit can be supplied as a dust filter only version or full NBC air filtration version.

S10 Outpost shelter air filtration

The dust filter removes dust particles to keep the shelter clean. This version is normally used for the storm shelter models which do not require NBCE protection. For this version, the filter elements can come into direct contact with human skin since the only contaminant is physical dust particles.

The Nuclear-Biological-Chemical or NBC version S.E.A.M. is a “Bag-In/Bag Out” (BIBO) NBC air filtration system designed for long-term operation in severe NBC environments. The NBC filter housing is made of stainless steel. The generator SEAM supplies NBC filtered air directly to the generator room when the generator is operating. This system allows maintenance on a generator that is free of NBC contamination since its combustion and cooling air is NBC filtered air which is a military requirement. In order to qualify as a long-term NBC air filtration system for more than 30 days, the HEPA and carbon trays have to be able to be removed and replaced. The trays are replaced using a “bag in bag out” system so there is no human contact with the contaminated filter elements. On the front side of the filter housing is a vacuum dial gage which indicates when the filter is operating normally and when the filters need to be changed. In the case where the shelter is located near a nuclear air, ground, or surface burst detonation putting fallout into the atmosphere, any HEPA filter in any air filtration system located in the shelter will become too radioactive and dangerous to the shelterists to keep in the filter housing even though the vacuum gage may read normal. The level of radioactivity in the filter comes from radioactive contaminants in the HEPA filter tray which can be measured by a radiation meter by just standing in front of the access doors and holding the radiation meter at the center of the access cover. When the reading is above 1 rad/hr., the HEPA filter should be changed.

Almost all of the initial fallout will have fallen in the first 24 hours so changing the HEPA filters should automatically be implemented after this period. Specific procedures are found in the S10 Outpost OPERATOR MANUAL for replacing filter elements. The SEAM system for life support is located at the far end of the shelter and supplies 40-200 cfm of fresh NBC filtered air and operates 24 hours per day. The air filtration system consists of three stages of air filtration. The first stage is a HEPA filter to remove physical particles that are 0.3 microns and larger at 99.999% efficiency. The second filter tray is activated carbon to remove radioactive iodine gas and has a minimum residence time of .25 seconds. The third filter tray is TEDA carbon to remove chemical warfare agents with a minimum residence time of 0.25 seconds. Each carbon tray weighs approximately 35 lbs. and any of the trays can be changed by one person in approximately ten minutes. For extended Sealed Shelter Atmosphere durations, a Lithium Hydroxide carbon scrubber tray can be used. One Lithium Hydroxide tray will remove enough carbon dioxide for ten people to stay in the shelter for approximately 24 hours. The top of the NBC filter housing has a gas agent test port to test for chemical agents using the supplied Chemical Agent Test Kit. A radiation survey meter is also supplied.

STORAGE

The S10 Outpost has 320 lineal feet of shelving that is 11 inches wide and 18 inches high. More than 200 five gallon buckets can be stored on the shelves plus toilet paper, clothing, tools, and other items. A key feature of the S10 Outpost is that it has enough floor space and efficient wall geometry to allow equipment, such as shelving and furniture, to be placed against the wall near the edge of the floor.

AIR MANIFOLDS

Air enters and exits the shelter through the air manifold assembly. The spent breathing air containing carbon dioxide, heat, moisture, and odors exits the shelter at the ceiling of the shelter at the opposite end to the SEAM air filtration system and exits to the atmosphere at ground level through the screened openings in the air manifold steel dome. Air enters the shelter through a separate air manifold assembly. The pipe flange at the bottom of the air manifold assembly is connected to a seismic joint which connects to the shelter hull.

ENTRANCEWAY SEISMIC JOINT

The connection between the entranceway and the hull is made through a double axis seismic joint. This allows the entranceway to move independently without overstressing the hull end wall. The entranceway can be located within the frost line, while the shelter is well below the frost line. This creates tremendous stresses during winter months when the entranceway is forced up 0.5 – 1.25 inches due to frozen ground. The seismic joint removes these stresses by allowing vertical and lateral movement of the entranceway to maintain structural integrity during rolling ground motion from severe ground shock.

WATER SUPPLY

The S10 Outpost is designed to accept water from dedicated water well powered by the shelter power system, not powered on the local power grid, to prevent water pump damage from a HEMP weapon. A backup water pump can be kept in the shelter in the EMP vault. There are also optional 2500 gallon underground water tanks which supplies a six month duration for 6 people.

STANDARD ENTRANCEWAY

The standard entranceway is a 68 deg. 36 inch diameter entranceway with a 30 in diameter clear opening, is usually used for emergency escape and is connected to the shelter though a seismic joint. The 30 inch diameter clear opening manhole allows large people to enter the shelter quickly. The hatch cover is spring loaded to open and requires approximately 10 lbs. of force to pull closed. The hatch can withstand 350 mph winds and has no surfaces exposed to projectiles.

The hatch is made of structural steel and can withstand a fire reaching 1700oF for one hour while maintaining its structural integrity in compliance to ASTM E119. Although the hatch is not impenetrable, it is specifically designed to resist seven basic assaults from people trying to break into the shelter in compliance to P.O.P.

S10 Outpost Bomb Shelter Hatch Closed

S10 Outpost Bomb Shelter Hatch Open

WALK IN ENTRANCEWAY 45 DEG.

The main entranceway is through a 72 inch diameter tunnel at a 45 degree angle connected to the shelter through a seismic joint. The flush steel hatch at ground level is aerodynamically smooth with a clear opening of 30 inches x 60 inches. There is nothing for flying debris to hit and the hatch can withstand 350 mph winds and is designed to protect the shelter from a fire reaching 1700oF for one hour while maintaining its structural integrity in compliance to ASTM E119.

HATCH EXTERIOR AND INTERIOR LOCK

The S10 Outpost hatch opens from the outside with a special mechanical key that cannot be made from a locksmith. When the shelter is unoccupied, a mechanical hasp and padlock is used. When the shelter is entered, the hasp and padlock are taken into the shelter. When inside the shelter, the hatch can be closed by turning a dog lever and inserting a locking pin. The hatch cover is designed to resist 5 psi negative pressure (5,000 lbs.) of uplifting force caused by the negative pressure of a tornado or explosion and 40 psi (20,000 lbs.) of overpressure. The average time it takes for untrained or inexperienced people to enter the shelter is approximately 5-10 seconds per person.

SEALED SHELTER ATMOSPHERE

When ground fires are present around the hatch, the air blower should not be turned on to bring in fresh air. During this time, the shelterists must breathe in a sealed shelter atmosphere. The safe duration time is based on a 3% carbon dioxide limit. The time it takes for the shelter atmosphere to reach this limit is a function of the number of shelterists, degree of physical activity of the shelterists, and the volume of the shelter above the floor. Sealed Shelter Atmosphere graphs are provided for each specific shelter.

S10 Outpost sealed shelter atmosphere

INTERNAL PRESSURE CONTROL

The S10 Outpost uses 8 inch diameter stainless steel blast valves to prevent blast overpressure or underpressure from pressurizing the shelter injuring people. The valves are located inside the shelter where they can be easily serviced. These valves are normally open and close from blast overpressure or negative pressure maintaining the normal shelter atmosphere. The air inlet and outlet openings are also sized to allow overpressure choking as a redundant system. Blast valves are located inside the shelter directly above the SEAM air filtration unit and on the air outlet on the ceiling.

S10 Outpost Triple

PLUMBING SYSTEM

Water Filter-The shelter can be equipped with a sub-micron water filter for all water used at the sink, shower, and toilet. Two of the batteries will supply enough power to pump approximately 1000 gallons of filtered water from the tank or water well. The counter contains a large stainless steel utility sink where dishes, clothes, and pets are washed. The sink, shower, and toilet, drain into a sewage lift station which transfers sewage up to a high pressure septic system. The toilet room has a blower to keep the toilet room in negative pressure venting all odors to the ground surface. Fittings– The shelter entranceway contains NPTF thru-hull couplings below ground level, for plumbing and electrical connection to the water tank or well and bringing in antenna lines or a phone line. Toilet– The toilet used is a conventional flush toilet draining into the sewage lift station under the shelter floor. The sewage is pumped up to the septic tank through an internal and external hose. Shower– The fiberglass shower floor allows all water from the shower head to drain into the sewage lift station. NBC decontamination is performed in this shower using the supplied decontamination solution and spray bottle. Cooking –The NORAD S10M uses an electric double burner cooking stove located on the kitchen counter. The S10 Outpost civilian uses an alcohol cooking stove.

RADIATION SHIELDING

The protection factor (PF) of a shelter is the ratio of a radiation dose over smooth ground which would be received by an unprotected person, compared to the dose that would be received by a person in a sheltered location. For example, a PF of 40 means that a person would receive l/40th the radiation in a shelter compared to the radiation that he would receive unprotected. A PF of l00 = l/100th. This is the fraction of radiation that a shelterist would receive from overhead (not accounting for radiation entered through the entranceway). The PF alone should never be used to determine the radiation entering a blast shelter. The Half Value Layer Thickness (HVL) is the material thickness required to reduce the radiation dose to half. Earth has an HVL of 5.5 inches and concrete has an HVL of 4.7 inches will reduce the radiation dose to half.

Radiation shielding from overhead in the S10 Outpost is provided by 96 inches of earth at the crown of the shelter ceiling. With a TRS (Total Rems in Shelter at the shelter entrance) of 3 rems at 20 psi (0.6 miles from GZ of a 100 KT weapon), the shelterist would be safe. This 30 day dose is based on a 100 KT surface burst to maximize radiation fallout. (See of PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition, 737 pp, 2013). A shelters’s radiation dose must always be related to the shelter’s overpressure rating.

Based on the worst cancer cases (leukemia) from the Hiroshima and Nagasaki victims, a 10-rem dose may increase the cancer rates from the current rate of 352/100,000 up to 355/100,000. It should be kept in mind that the Hiroshima victims were totally unprepared and uneducated. They were malnourished and already suffering from many diseases during a critical wartime period where food, medical supplies, and other necessities were in short supply. In addition, they were not only exposed to heavy, acute external radiation doses but also internal radiation doses from eating contaminated food and inhaling radioactive fallout. Educated shelterists can avoid such damaging effects and can determine the radiation levels with a simple radiation survey meter supplied with the S10 Outpost along with a chemical agent detection kit.

EMERGENCY ESCAPE

In the event that heavy debris falls on the hatch cover and the radios are not able to bring help to clear the hatch, emergency escape procedures can be implemented. The S10 Outpost uses a manually operated mechanical jack to force the hatch open. The 18 inch long handle will require 50 lbs. downward force to generate 8,000 pounds of uplifting force.

INSTALLATION RIGHTS

U.S. citizens have a legal right to install a shelter. Under the second amendment of the United States Constitution, U.S. citizens are guaranteed the right to bear arms to provide protection in life threatening situations. Tornadoes, earthquakes, nuclear, biological, and chemical warfare fall under this amendment as life threatening forces. A disaster shelter falls under this classification as a defensive arm. The NORAD shelters are considered a temporary structure that can be redeployed to another location.

COMMUNICATIONS

The communications center consists of a HAM radio and scanner radio mounted inside a vented EMP aluminum shielded enclosure per MIL-STD-188-125, 50 ft. of antenna cable to allow antennas to be mounted on a nearby building or tree.
