We have all heard of people talking about a doomsday, or watched the TV show Doomsday Preppers. We have heard people called "Preppers", or "What Iffers". People have been talking about some sort of "End of the World" scenario, for decades. Even the United States government has many bunkers around the country, some of which have been, bought by ordinary citizens and even preppers. Some of us are concerned something may happen sooner than later. I have heard more and more people talking about the possibility of an imminent disaster. Some people worry about different possible scenarios. For example; economic collapse, societal collapse, civil unrest, electromagnetic pulse, weather destruction, war, fire, nuclear attacks, terrorist attacks, fuel shortages, pandemics, geomagnetic reversal, etc. Many people are preparing for these, scenarios of which they are concerned. It is estimated in the United States of America, approximately ten percent of the population are Preppers to one degree or another. No one knows if or when, one or more problems will occur. There is no way to predict a specific occurrence or time factor, and my crystal ball broke, so I cannot help with your prognostication. The best we can do is to be prepared for any eventuality. This is why I personally (and many others) believe an underground concrete bunker is the best idea. As I will explain, this Bunker will give you the best protection possible for the most scenarios. One need not be a conspiracy theorist to be concerned. People may think "Doomsday Preppers", or "What Iffers", as we are often called, are "nut jobs." However, when TSHTF, we will be the ones who others will come to, since we will be prepared. Common Design Flaws Some of the problems I have seen with bunker designs are: There is not enough food storage There is not enough water storage The bunker is not deep enough underground to protect from radiation or chemical contamination The bunker is not designed to be able to withstand the amount of pressure from the tonnage of dirt above The air circulation is not adequate The air is not adequately filtered for NBC (Nuclear, Biological, Chemical) contamination The water is not sufficiently filtered There are no accommodations for pets. There is no accommodation (or insufficient accommodation) for waste and elimination. Bunkers are too crowded and claustrophobic for long-term occupancy. Security is woefully inadequate. There is no adequate plan for replenishing the water There is no adequate plan for replenishing the food Steel shipping containers do not supply the protection needed, nor are they able to be buried deep enough underground for adequate protection. There is no escape plan There is no second exit What about electricity? No plan for backups No bug-out kits prepared No drills planned Occupants are not knowledgeable about nuclear protection.
