Using the J20 Shelter for Tornadoes and Hurricanes

The J20 is designed and equipped to be occupied before the disaster arrives. It is designed to encourage owners not to follow the “OZ” method of protection: waiting to shelter until the last moment, then running their fastest straight into deadly flying debris. With 904 ft3 volume and 103 ft2 floor space, the J20 is large enough for pre-disaster use. It is installed with a solar-powered battery that charges the lighting, air blower and hazard alert radio. The sitting area is comfortable, with no long-term crouching or standing required. You can get inside the shelter before the tornado reaches your home, which is the only safe time to protect yourself

Protection from 350 mph Flying Debris

Flying debris is the main cause of tornado injuries and deaths. When people avoid hot, cramped conventional shelters until the tornado funnel is in sight they are more likely to get hit by flying debris on their way to the shelter. The NORAD goal is to get people to shelter PRE-DISASTER by supplying a spacious shelter environment, lighting, fresh air, seating and a comfortable temperature.

Underground Safety

An above ground tornado shelter meeting FEMA 361 and ICC 500 2014 missile guidelines must withstand a 15 lb. 2×4 traveling at 100 mph. A tornado can hurl a 3,000 lb. car at 220 mph. The NORAD J20 tornado shelter is superior to ICC 500 2014 missile guidelines because the shelter is underground where flying debris cannot reach it.

J20 Disaster Shelter Construction

The J20 is made of structural steel in compliance to American Society of Testing and Materials (ASTM) and PRINCIPLES of PROTECTION engineering standards. Steel was chosen as the optimum material because of its extremely high resiliency. Steel can be cathodically protected and it can be shaped into a compound curved structure.

In addition, one of the greatest characteristics of steel is its ability to “remain intact” if overstressed. The inside of the shelter is smooth, curved, and white to create maximum brightness with minimal light. All of these facilities function without outside electricity through the use of a 2 12-volt, deep-cycle AGM batteries. The inside surface is easily cleaned with common detergents and is easily repaired.

The 5 psi external pressure resistance, with no earth arching, is constant over the 50 year warranty and does not have to be de-rated each year like conventional steel structure with no corrosion protection. Steel also forms a complete vapor barrier which provides a dry atmosphere when placed below ground and is also a barrier against radon and methane gas found is most soils. It has also proven to be sound in the underground storage tank industries.

  • Cathodically Protected
  • Maximum Brightness and Light

  • Water and Vapor Barrier

Shelter Facilities

The J20 contains 904 cubic feet with 6′-2″ to 8 ft. of headroom. This allows people to stand up or sit down on the benches. There is ample light for reading anywhere in the shelter supplied by an LED light located near the shelter ceiling.

J20 tornado shelter hatch light and stairs

Fresh Air

Fresh air is brought into the shelter by a 12-volt 200 CFM air blower mounted to a screened air inlet manifold and designed to operate 24 hours. The blower supplies many times the breathing volume of air required by adults and produces a complete air change inside the shelter every 4.5 minutes. 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. Exhausting of hot, moist, spent air is facilitated through the screened air outlet at the highest point in the shelter where it exits the shelter. This is the most efficient geometry for exhausting spent air.

  • 5 Minute Air Exchange
  • Substantial Air Supply
  • Comfortable, Constant Shelter Temperature
  • Constant Carbon Dioxide and Moisture Levels
  • Efficient Spent Air Exhaust
  • Overheating Prevented

Shelter Electrical Power

Two 140 AH AGM batteries provide power for 24 hours of operation. The normal loss of battery power is approximately 1.5% per month when the battery charger is not operating. A photovoltaic panel (solar panel) is supplied to maintain the battery charge level. An optional 6-amp 115 volt AC controlling battery charger can be mounted in the shelter to maintain the battery charge from outside AC power. A thru-hull coupling in the shelter entranceway is used to connect an underground cable from the shelter to the nearest power supply.

  • 24 hour Electrical Power
  • Solar Battery Charger
  • Optional AC Battery Charge

Shelter Hatch

The J20 is supplied with a commercial steel hatch with a 30 inch diameter clear opening. The hatch and air manifolds are recessed below ground level so the hatch is protected from flying debris. The hatch is locked when the shelter is not in use. The lock is a heavy plate hasp and padlock which are removed and taken into the shelter.

J20 tornado shelter hatch and berm

Cathodic Corrosion Protection System

A buried galvanized tank or steel culvert becomes unsafe over time. Underground tornado shelter protection is superior to above ground concrete protection, but not if corrosion safeguards are missing. Underground steel without corrosion protection loses 2 to 5% of its strength each year. The steel corrodes and weakens. A regular epoxy coating only slows down the corrosion process. The NORAD tornado shelter dielectric (electrically insulating) epoxy coupled to a cathodic protection system with anodes directs the electrical corrosion process to the anodes and stops the corrosion process. Since corrosion is a natural process, tornado shelter companies only warranting their product against “defects in workmanship” can disclaim responsibility when tornado shelter owners report hull weakening, leaving owners with shelters too corroded and therefore unsafe to use.

Jupter 20 tornado shelter cathodic protection anodes

Ground Fires and 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. This duration is shown in the adjacent graph for adults performing mild work producing 0.67 ft3 of carbon dioxide per hour. For locations subject to forest fires, a carbon dioxide scrubber option is recommended extending the sealed shelter atmosphere 24 hours for 6 people. Shelters ordered for forest fires will be manufactured with a heat shield on the underside of the hatch.

J20 Disaster Shelter Design

The J20 is a third generation Storm Shelter designed and developed by Walton W. McCarthy, M.E., author of PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition 2013, Brown Books. Principles of Protection is the United State’s bible on shelter engineering. It’s available on Amazon and several other online book stores.

McCarthy’s nuclear protection shelter and disaster shelter engineering history is documented on wikipedia.org. McCarthy has over 40 years’ experience designing “high-tech” underground shelters.

The J20 was designed using CAD (computer aided drafting), CAE (computer aided engineering), and FEAM (3-dimensional finite element analysis and modeling). The tube dome shape of the J20 allows it to be a true pressure vessel for resistance to high external pressure and full height water tables. The J20 shelter system is based on 40 years field experience with McCarthy’s successful CAT 25, H10 Commander, and H12 Admiral underground shelters.

Jupiter 20 Wind Protection from Tornadoes and Hurricanes

We use the Enhanced Fujita Tornado Scale (EF) and the Saffir-Simpson Hurricane Wind Scale (SSWS) to describe tornadoes and hurricanes. The EF wind speeds are actually not measured, but are an educated guess inferred from the Beaufort Wind Scale combined with the observed tornado damage. The SSWS wind speeds are based on wind speed measurements.

The original Fujita Scale was replaced in 2007. Under that system an F5 tornado topped out 317 mph 3 second gust. Under the EF scale, an EF5 tornado is described as a 3 second gust “greater than 200 mph” with an upper bound of 220 mph. The SSWS top Category 5 hurricane has sustained winds “greater than 157 mph.”

The Jupiter 20 Storm Shelter protects occupants from 350 mph wind-borne missile debris.

Second Amendment 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, hurricanes, fires and earthquakes fall under this amendment as life threatening forces. A Storm Shelter falls under this classification as a defensive arm. The NORAD J20 Disaster Shelter does not have a foundation or running water and therefore usually does not fall under the local building codes.

Americans have the right to defend themselves.

Shelter Installation

The J20 should be installed so the hatch is at least one foot above the 100 year flood plain or two feet above the 100 year storm surge.

Summary of Shelter Installation Steps

The excavator digs a hole that is 20 ft wide, 20 ft. long and 11.5 ft. deep.

1-3 inches of pea stone or sand is place on the bottom center of the hole and leveled.

The crane lifts the 10,500 lb. J20 off of the truck, tracks it back to the excavated hole, and lowers the J20 into the hole.

The shelter is leveled at the proper height at the bottom of the hole by shoveling pea stone under the bottom of the shelter gravity flange.

The shelter is then backfilled with 20 yards of pea stone to be shoveled under the base. If sand is used, it must be compacted with a “Jumping Jack” or watered. After this stage, the surrounding soil can be used for backfill and must be compact­ed evenly around the shelter.

When the backfilling reaches 12 inches below ground level, the thru-hull coupling can be used to connect the shelter to outside power, telephone lines, antenna lines etc.

Backfill­ing continues to the original ground level. Back­filling usually requires approximately 4 hours.

Warranty

NORAD Shelter Systems LLC® Warranties that the hull of the J20 Disaster Shelter will not structurally fail for 50 years provided that 1) the shelter is not exposed to excessive overpressure 2) The structural parts of the shelter are not modified 3) The shelter is inspected, off-loaded, assembled, backfilled and installed in accordance with the company’s installation instructions; 4) structures are not built on top of the shelter. NORAD further warranties that any significant damage to the shelter or hatch from a tornado will be covered during this warranty period. The warranty does not apply to the parts and equipment that NORAD does not manufacture. These items are covered by the individual manufacturers. NORAD Shelter Systems LLC® is continuously improving its product and therefore reserves the right to change any specification without notice. Our liability under this warranty shall be limited to, at our option, repair of the shelter, or delivery of a replacement shelter to the point of original delivery, or refund of the original purchase price. We shall not be liable for any indirect or consequential damages, labor, or installation costs.

The only Jupiter 20 element exposed to the storm is the hatch, which NORAD will replace in the very unlikely case that it sustains storm damage. Because the hatch is horizontal and at ground level it is not subject to flying debris. The hull is underground where it can’t be hit. The Jupiter 20 tornado shelter protects you from the deadliest part of the storm: the flying debris. Even a car landing on the shelter spot will not hurt the shelter or the people inside.

The hatch is locked when the shelter is not in use. The lock is a heavy plate hasp and padlock which are removed and taken into the shelter.

Cathodic Corrosion Protection System

A buried galvanized tank or steel culvert becomes unsafe over time. Underground tornado shelter protection is superior to above ground concrete protection, but not if corrosion safeguards are missing. Underground steel without corrosion protection loses 2 to 5% of its strength each year. The steel corrodes and weakens. A regular epoxy coating only slows down the corrosion process. The NORAD tornado shelter dielectric (electrically insulating) epoxy coupled to a cathodic protection system with anodes directs the electrical corrosion process to the anodes and stops the corrosion process. Since corrosion is a natural process, tornado shelter companies only warranting their product against “defects in workmanship” can disclaim responsibility when tornado shelter owners report hull weakening, leaving owners with shelters too corroded and therefore unsafe to use.

Ground Fires and 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. This duration is shown in the adjacent graph for adults performing mild work producing 0.67 ft3 of carbon dioxide per hour. For locations subject to forest fires, a carbon dioxide scrubber option is recommended extending the sealed shelter atmosphere 24 hours for 6 people. Shelters ordered for forest fires will be manufactured with a heat shield on the underside of the hatch.

J10 Disaster Shelter Design

The J10 is a third generation Storm Shelter designed and developed by Walton W. McCarthy, M.E., author of PRINCIPLES of PROTECTION, U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Standards, Sixth Edition 2013, Brown Books. Principles of Protection is the United State’s bible on shelter engineering. It’s available on Amazon and several other online book stores.

McCarthy’s nuclear protection shelter and disaster shelter engineering history is documented on wikipedia.org. McCarthy has over 40 years’ experience designing “high-tech” underground shelters.

The J10 was designed using CAD (computer aided drafting), CAE (computer aided engineering), and FEAM (3-dimensional finite element analysis and modeling). The tube dome shape of the J10 allows it to be a true pressure vessel for resistance to high external pressure and full height water tables. The J10 shelter system is based on 40 years field experience with McCarthy’s successful CAT 25, H10 Commander, and H12 Admiral underground shelters.

Jupiter 10 Wind Protection from Tornadoes and Hurricanes

We use the Enhanced Fujita Tornado Scale (EF) and the Saffir-Simpson Hurricane Wind Scale (SSWS) to describe tornadoes and hurricanes. The EF wind speeds are actually not measured, but are an educated guess inferred from the Beaufort Wind Scale combined with the observed tornado damage. The SSWS wind speeds are based on wind speed measurements.

The original Fujita Scale was replaced in 2007. Under that system an F5 tornado topped out 317 mph 3 second gust. Under the EF scale, an EF5 tornado is described as a 3 second gust “greater than 200 mph” with an upper bound of 220 mph. The SSWS top Category 5 hurricane has sustained winds “greater than 157 mph.”

The Jupiter 10 Storm Shelter protects occupants from 350 mph wind-borne missile debris.

Second Amendment 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, hurricanes, fires and earthquakes fall under this amendment as life threatening forces. A Storm Shelter falls under this classification as a defensive arm. The NORAD J10 Disaster Shelter does not have a foundation or running water and therefore usually does not fall under the local building codes.

Americans have the right to defend themselves.

Shelter Installation

The J10 should be installed so the hatch is at least one foot above the 100 year flood plain or two feet above the 100 year storm surge. The J10 can be installed in a backyard or under a garage concrete floor. Garage installations are easiest before the garage footings are poured. Normally the shelter is installed on the center line of each car bay in the garage or between the two bays so the hatch is positioned between the two front tires of the car. This will work as long as the inside distance between the tires is greater than 40 inches. When entering the shelter during high wind use, the garage door should be opened at least 6 inches to allow fresh air to enter the garage where both inlet and outlet exchange air must take place for life support.

  • ONE DAY INSTALLATION
  • NO POST-STORM DOWNTIME
  • EVERYTHING IS WARRANTIED, INCLUDING THE HATCH

Summary of Shelter Installation Steps

The excavator digs a hole that is 12 ft wide, 12 ft. long and 8.5 ft. deep.

1-3 inches of pea stone or sand is place on the bottom center of the hole and leveled.

The excavator lifts the 3,500 lb. J10 off of the truck, tracks it back to the excavated hole, and lowers the J10 into the hole.

The shelter is leveled at the proper height at the bottom of the hole by shoveling pea stone under the bottom of the shelter gravity flange.

The shelter is then backfilled with 10 yards of pea stone to be shoveled under the base. If sand is used, it must be compacted with a “Jumping Jack” or watered. After this stage, the surrounding soil can be used for backfill and must be compact­ed evenly around the shelter.

When the backfilling reaches 12 inches below ground level, the thru-hull coupling can be used to connect the shelter to outside power, telephone lines, antenna lines etc.

Backfill­ing continues to the original ground level. Back­filling usually requires approximately 4 hours.

Warranty

NORAD Shelter Systems LLC® Warranties that the hull of the J10 Disaster Shelter will not structurally fail for 50 years provided that 1) the shelter is not exposed to excessive overpressure 2) The structural parts of the shelter are not modified 3) The shelter is inspected, off-loaded, assembled, backfilled and installed in accordance with the company’s installation instructions; 4) structures are not built on top of the shelter. NORAD further warranties that any significant damage to the shelter or hatch from a tornado will be covered during this warranty period. The warranty does not apply to the parts and equipment that NORAD does not manufacture. These items are covered by the individual manufacturers. NORAD Shelter Systems LLC® is continuously improving its product and therefore reserves the right to change any specification without notice. Our liability under this warranty shall be limited to, at our option, repair of the shelter, or delivery of a replacement shelter to the point of original delivery, or refund of the original purchase price. We shall not be liable for any indirect or consequential damages, labor, or installation costs.

The only Jupiter 10 element exposed to the storm is the hatch, which NORAD will replace in the very unlikely case that it sustains storm damage. Because the hatch is horizontal and at ground level it is not subject to flying debris. The hull is underground where it can’t be hit. The Jupiter 10 tornado shelter protects you from the deadliest part of the storm: the flying debris. Even a car landing on the shelter spot will not hurt the shelter or the people inside.

NORAD UNCONVENTIONAL UNDERGROUND COMMERCIAL TORNADO SHELTERS

The conventional approach to building commercial tornado shelters uses conventional construction technology, which does not protect people or structures very well. FEMA 361/ICC 500 require flying debris protection well below the weight, speed and size of debris reasonably expected from a strong tornado. Flying debris will still damage above ground concrete structures meeting FEMA/ICC, possibly requiring structural, electrical, plumbing and mechanical repairs that can cost many thousands of dollars and taking many months to complete.

NORAD UNCONVENTIONAL COMMERCIAL TORNADO SHELTERS

NORAD Commercial Underground Tornado Shelters are UNCONVENTIONAL structures that sit beneath the damaging winds, literally out of harm’s way. Structural hardening and the earth cover protect people from 350 mph flying debris without causing shelter damage. NORAD Tornado Shelters protect people from greater than F5 tornadoes with a post-tornado re-fitting cost of no more than $3,000 to replace solar panels and antenna equipment.

PROTECTION FROM 350 MPH FLYING DEBRIS

Flying debris is the main cause of tornado injuries and deaths. When people avoid hot, cramped conventional shelters until the tornado funnel is in sight they are more likely to get hit by flying debris on their way to the shelter. The NORAD goal is to get people to shelter PRE-DISASTER by supplying a spacious shelter environment with 8-10 ft. cathedral ceilings, plenty of bathrooms, cold running water, good lighting, fresh filtered air and a comfortable temperature.

ENCOURAGING PRE-DISASTER SHELTERING

Getting people to PRE-DISASTER shelter drastically reduces the chances of injuries and deaths from last-minute sheltering. PRE-DISASTER sheltering means people are safe well before the tornado arrives. By encouraging PRE-SHELTERING, NORAD Tornado Shelters reduce the fiscal and tragic costs of unnecessary tornado injuries and deaths. Tornado throws school bus onto school roofThe NORAD goal is for people to use the Tornado Shelter PRIOR to the disaster reaching the school or office building. The NORAD shelter design is large enough, designed well enough, and equipped well enough to promote PRE-DISASTER use. Staff and students can be in the shelter PRIOR to the tornado arriving on site which avoids large groups of people rushing to the shelter during high winds.

S30x80 Commercial Underground Tornado Shelter

Conventional tornado shelters are usually made of concrete which is subject to cracking and microbial growth. A conventional shelter meeting FEMA 361 and ICC  500 2014 missile guidelines must withstand a 15 lb. 2×4 traveling at 100 mph. A tornado can hurl a 3,000 lb. car at 220 mph, which would damage a conventional shelter’s walls, roof, plumbing and electrical systems. Damage would cost thousands of dollars while the population waited for months for repaired tornado shelter protection. A 220 mph 3,000 lb. car would not damage a NORAD Tornado Shelter or the people inside. The hull protecting people is underground. The hatches are flush with the ground. The air manifolds sit at a 15 degree angle approximately 5 inches above ground. Horizontal flying debris passes over the NORAD shelter. Even if the wind picked up a 20,000 lb. truck and dropped it on the shelter site, the earth above the shelter and the shelter’s seismic joints would protect the people inside as well as the shelter’s structural integrity. NORAD Commercial Underground Tornado Shelters protect against 350 mph flying debris. They come with a 30 year structural warranty which replaces broken hatches and air manifolds in the unlikely event that a horizontal debris crashes into or debris falls vertically onto the shelter site.

FORMAL CATHODIC CORROSION PROTECTION SYSTEM

A buried galvanized tank or steel culvert becomes unsafe over time. Underground tornado shelter protection is superior to above ground concrete protection, but not if corrosion safeguards are missing. Underground steel without corrosion protection loses 2 to 5% of its strength each year. The steel rusts and weakens. A regular epoxy coating only slows down the corrosion process. A dielectric (electrically insulating) epoxy  coupled to a cathodic protection system with anodes directs the electrical corrosion process to the anodes and stops the corrosion process on the NORAD underground steel structure. Since corrosion is a natural process, tornado shelter companies only warranting against “defects in workmanship” can disclaim responsibility when tornado shelter owners report rust and hull weakening, leaving owners with shelters too corroded and therefore unsafe to use.

30 to 50 YEAR STRUCTURAL WARRANTY

NORAD hulls are all steel with a 30-50 year cathodic corrosion protection system allowing for a 30-50 year structural warranty.  The system includes a meter to monitor the electrical corrosion protection process.  Protection can be upgraded to 40 or 50 years at installation, and can be re-applied at the end of the anode lifecycle to extend corrosion protection for another 30 to 50 years.

NORAD Tornado Shelters are Pre-Fabricated and Installed On-Site Usually in 7-14 Days

SAFER, STRONG, STEADIER THAN CONCRETE

NORAD Tornado Shelters use no concrete. This steel tornado shelter installs quickly partly because it has no month-long concrete drying times.  The NORAD Tornado Shelter’s steel foundation is more structurally stable, more resilient and can take a greater ground shock than a reinforced concrete foundation. The steel foundation also acts as a barrier to radon and methane gas in the soil, which will permeate concrete and enter the shelter.

REDEPLOYABLE

As schools and business grow they erect new structures, sometimes requiring the land occupied by an above ground conventional tornado shelter. Conventional tornado shelters built on-site cannot be moved. They must be taken down to make room for new structures. To expand the facilities the institutions destroy the existing shelters and the investment that went into them.

INSTALL IN ONE OR TWO WEEKS

NORAD Tornado Shelters are made from steel hull sections that bolt together on site taking only about a week to install. They use no concrete which would require jack hammering to remove. Should land use plans change after the NORAD Tornado Shelter installation, NORAD shelters can be dug up and moved with no impact on the structure’s integrity and usefulness. There are removal and re-installation costs, but the shelter investment is not sacrificed. NORAD Tornado Shelters have maximum shelter re-deployability.

FRESH FILTERED WATER, REGULAR FLUSH TOILETS

The NORAD Tornado Shelter uses solar power to run the conventional pressurized plumbing system. The shelter connects to a dedicated well for drinking water or to an optional water tank with trucked-in fresh water. Bathrooms have sewage lifts to the septic leach tank. Each bathroom has a sink with cold running water. At least one bathroom is ADA-compliant. There is a minimum of one bathroom per 50 people but NORAD shelters can easily accommodate more bathrooms per person. Bathrooms are under constant negative pressure to remove odors. The shelter uses conventional flush toilets rather than “port-a-potty” chemical toilets which can be unpleasant and limited in duration.

Fresh filtered air is brought into the tornado 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.

The emergency jack lifts 16,000 pounds off the hatch preventing people being trapped inside. The walk in 45 degree stairwell entranceway allows an adult person to enter every 5 seconds.

Principles of Protection
Principles of Protection

30 TO 50 YEAR WARRANTY AGAINST STRUCTURAL DAMAGE

Conventional tornado shelters often come with no warranty, with better companies offering “limited lifetime warranties for any defects in material workmanship.” A “workmanship” warranty doesn’t promise the shelter will stand up to 350 mph tornado winds, making the tornado shelter owner responsible for the expensive post-tornado repairs. Complete shelter destruction is not a defect and so is not covered under these warranties. Buyers have no recourse except to repair, re-build and replace the tornado shelter. NORAD Tornado Shelters are warrantied for 30 years against structural failure. The NORAD shelter hull is not exposed to Tornado winds. The air manifolds and hatches are flush with the ground to resist 350 mph winds. A 30 year corrosion protection system is included with all NORAD Tornado Shelters. Protection and the associated warranty can be upgraded to 40 or 50 year lengths.   NORAD Tornado Shelters meet numerous scientific and engineering specifications and standards, a few of which follow:
