This was an informative article, but I would like to see a bunker industry comparison of bunkers. Perhaps this has been done, but I just haven’t run across it yet. If anyone knows of any credible and objective comparisons, I’d be interested in knowing the link to that info. Right now, I’m considering Rising S, Vivos, or Bombardo. I don’t need an underground city, nor do I like communal life (been there, done that in military). I just want a functional bunker for 4 to 6 people that is reasonably priced and will last for a long time.
Communication: Our preferred portable radio is the BeoFeng BF-F8HP 8-watt two-way radio. You don’t need a Ham license to listen to local emergency services and broadcast when SHTF — see our beginners guide to amateur radio. We like this signal mirror instead of the cheap acrylic ones that scratch and fade quickly. Also, try these tiny whistles and signal flare kit.
Dozens of earthquakes gave Hawaii residences a 48 hour warning before the volcano erupted. The average warning time for California wildfires victims was 20 minutes. Japan’s tsunami victims had a 15-minute warning. Being one of the first to know about oncoming dangers can provide you a head-start. Emergency alert systems are a great preparedness resource. There are several companies that provide emergency alerts services and many of them are free.  There are also a couple of different ways to receive alerts. Modern technology has given us many different methods to be notified of possible threats. Here are several options to consider.

Check dried goods: rice, flour, grains – frequently for bug infestation. You can mix food grade diatomaceous earth in with dried goods and it will kill pantry moths and weevils. It is safe for humans and pets (as long as it is food grade). It works by shredding the exoskeletons of any soft bodied bug. It is used in grain silos to keep bugs from infesting grain. You can probably get some through a feed store. Some garden centers carry it. You can also order it online, but check the shipping cost. Pantry moth larva and weevils can squeeze through some very tight fitting lids. We’ve been fooled often by them.
I can sleep at night because I’m well on way to having a year’s worth of the highest quality food freeze dried with a 20 year shelf life. I also am a huge fan of Berkey Water filters. We live in an intense chicken, turkey, hog barn agribusiness area – lots of potential harm to our water supplies besides roundup. Berkey is king if you read the independent lab reports – it does the best job purifying the water while keeping the needed minerals in the water your body needs.

And I have bought various pantry sized cans of sauces to increase flavor and nutrition. Alfredo sauce, tomato sauce, mild hot sauce, and Italian seasoning mix come to mind immediately. Since those cans are so well sealed, I don’t bother putting them in the buckets. I also have some #10 cans of cheese sauce powder (think boxed Mac and cheese) since I couldn’t find it in a pantry can, but I store lots of ziplock freezer bags (both quart and gallon sizes) and can use my silica packs to keep it fresher – hopefully long enough to use it up. Cheese sauce over pasta, rice or broccoli will be a nice change of taste when things get boring.
Some lights are crank powered like our emergency radio above and having at least one of those is not a bad idea. Alternate light sources are candles, which are cheap but present a fire hazard, or chemlights, which are completely safe and heatless, but also have utility for marking, safety and signaling. Redundancy is a good idea, but emphasize flashlights and headlamps. Both require…
Mass is what blocks radiation. Concrete is useful because it’s both dense and strong, so it gets used in a lot of bunker construction. Steel is also useful, but it can become radioactive itself by neutron activation. (So close to ground zero, you’ll need to protect the steel from neutrons – boron or water are the most common ways to reduce neutron flux damage to the protected space.) But there is no reason you can’t use lots of dirt, water, stone, etc. Anything that has mass will attenuate radiation.

Not so sure I agree with some of this list. Sure, you need to clean water, shelf-stable foods and alternative ways to cook it, but not so sure I would recommend beginning preppers bother with a rifle or seeds quite yet. I would suggest they worry about items like a comprehensive first aid and hygiene/sanitation concerns first. You need to be able to get through a disaster before you should worry about a long term survival scenario.

One major upside of freeze-dried food is its convenience. Since all its water content has been removed—via a process that involves exposing food to subzero temperatures, while removing the resulting water vapor with a vacuum—it’s easier than canned goods to transport on the fly. To “cook” Wise Company’s six-grain Apple Cinnamon Cereal, you just boil three and a half cups of water, dump in the powdery contents of the bag (minus the oxygen absorber), and cover the pot for 12 to 15 minutes.
