What is a Bomb Shelter?

Years ago shelters were very different they were designed in various types such as: expedience, personal or family, community, multi-purpose, and hidden.

Generally, an expedience fallout shelter was built in a trench with a heavy-duty roof buried beneath three feet of dirt. Both ends of the trench shelter had inclines down or the entrances were at a right angle to the trench so that the gamma rays were unable to enter. They would make the roof waterproof so in possible chance of rain, it would not leak. They did this by using a plastic sheet that was buried just a few inches under the surface and used rocks and or bricks to hold it in place.

The most inexpensive bomb shelter was built in the corner of a basement, and it hypothetically offered considerable protection. In many of the plans, the walls were made of concrete blocks. Ventilation was provided by an open doorway and or vents near the floor. The constructed the entrance to the shelter with a sharp turn to lessen the intensity of the radiation. The civil defense authorities back then, believed a basement shelter built out of concrete block could be a do-it-yourself project for $150 to $200 at that time. Precisely how much protection it truly gave you was an unanswered question.

Other sites that individuals used for such a structure besides a basement was, they would convert an old underground cistern, below earth root cellar and many other below-ground sites. Even just four feet of dirt or a couple of feet of concrete would lower the level of (not stop but lower the level of) gamma-ray radiation that would reach the family in an underground bunker.

Concrete was the preferred building material of underground bomb shelters, with the walls being at least 12 inches thick.

The federal government suggested that bomb shelters be built in a basement or better yet an underground concrete bunker buried in the backyard. This was to get as much bulk as possible between survivors, the explosion, and its after-effects.

Today an underground concrete bomb shelter is a sealed off, sheltered room or rooms which have been built in such a way as to protect you from nuclear, biological, natural and man-made threats. When we use the word sheltered, we mean “underground”. A minimum of 4 feet of soil covers the top of the shelter, shielding the occupants from radioactive fallout. The underground concrete shelter should be built in such a way as to provide maximum protection from numerous types of disasters such as but not limited to a nuclear attack. In the even the threat in Nuclear, this primarily means you will need shielding from the blast wave and protection from radioactive fallout. So what is the difference, bomb shelter, fallout shelter, underground concrete bunker, survival shelter, NBC shelter, nuclear bomb shelter, underground nuclear concrete shelter, etc. you can call it whatever you want they all basically mean the same thing. But remember just because the name is the same, does not mean they are built the same. All the research from way back have always said concrete is the best for protection. We at NWSS only build with concrete no prefab or thin metal housing from our company. When you put your family’s security in our hands we treat it as if it was our own family.

So what about those other options, gun vaults, panic rooms, safe rooms? A panic room is another name for safe room. Most security experts use the expression Safe Room instead of Panic Room to define the idea of having a high security location within your home. The concept is relatively simple, building a room within the inside of the home where you and your family can safely hide during a home invasion or other terrorist threat and call for help.

Consider a safe room as a box with only one entrance. You simply reinforce all six sides of the box and hide a single door leading into it. We at NWSS build some of our safe rooms more like a bunker or bank vault some with eight-inch concrete walls and a concrete filled vault blast door. These more extravagant designs are also used to store such things as cash, valuable jewelry, and collections. We have built others where we have reinforced the walls and equipped the room with a video monitor system, a cellular type telephone, and also added an alarm keypad.

Why would I want a Safe Room?

Unlike in the movies, most people that want a safe room want one simply built to give them enough time to get inside the room and activate an alarm or call the police for help. There are several reasons for a safe room, with the most common being fear of assault from a home invasion robber or even an abusive spouse. One of the most common reason for celebrities, politicians or just people that are considered to be rich and or have serious enemies to construct a safe room is the fear of home invasion robbery and or the horror of kidnapping for ransom or revenge.

If you ever wondered what the chances are that an intruder will find his way into your home, you’ll want to read on. The fact is, the United States leads the world in occurrence of burglaries and about four burglaries occur every minute; that’s one every 15 seconds.

What could be more horrifying or deadlier than home invasion, specifically if it could possibly include murder? Almost daily there is news of home invasion murders.

Home invasion, includes all crimes including battery, burglary, robbery, assault, rape and murder. According to the data collected by the Statistics USA and FBI –

  • One home burglary occurs every 15 seconds.
  • Most of the home invasions occur through the front door.
  • 1 out of 5 homes that are victimized by a home intruder involve murder or some type violent crime.

These are disturbing statistics. It has also been detected that insecure are targeted by criminals. The criminals appear to be aware that even if the home has a security system, that most homeowners do not generally activate it until they go to bed. So that means, the perfect time to break in is before bedtime, which brings the risk much higher for a violent invasion or even murder.

Home Invasion

A burglar is typically stoned faced and carries a weapon, which leaves you and your family at the mercy of the intruder. If the demands of that intruder are net met, such as handing over your valuables, cash or whatever they want, the result can be violent and even fatal.

The burglar usually comes in through the front door, which if there is no security alarm or if the alarm is not activated is very easy. While many home intruders may kick the door open, others might just knock on the door or ring the doorbell. Really, I bet you never thought the intruder would be so bold as to come calling like a wanted guest?

According to some statistics, intruders will also pretend to be a milkmen, a maintenance worker or even a police officer to get you to open the door. Some may even pretend to have a broken down car and they would be ever so grateful if you would let them you your phone to call a tow truck.

These reports also stated that the home intruders show no discrimination among their victims. It does not matter whether are rich or poor as long as you are an easy target.

Home Intruder Murders: Statistics The U.S, Department of Justice conducted a survey and released its special report on National Crime Victimization in September 2010. According to this report;

  • Approximately 3.7 million burglaries occurred every year from the years 2003 to 2007. A member of the house was present is 28% of these burglaries. 7% of the members were victimized.
  • In 65% of the home invasions and victimizations, the homeowner and the family knew the invader. Only 28% of the invaders were strangers.

According to these survey reports and statistics, it has been observed that home invasion murderers do not discriminate when they set out to commit the crime. If their crime is interrupted or if the household member resists their demands, they then become victimized. Don’t be a statistic and more importantly don’t become a victim or violence.

We keep your privacy to yourself. If you buy a prefabricated shelter you have to have it delivered. That is a minimum of 1 to 2 people at your site that now knows what you have there. Then you have to have it buried in the ground which means at least 1 or 2 local operators with equipment to dig a hole and bury it. Then you will need a crane and operator to take it off the truck and place in said ground, adding again 1 or 2 more local people who knows it’s there and now the location of it. And before you bury it you will have to have concrete delivered and poured over the whole thing, this will include several more local people who now know what you have, where it is located and most likely where the entrance to it will be. That is a great deal of locals that now know where you are hiding your families safety.
