What To Store In Your Faraday Cages?

Here is a list of suggested items that you may want to consider placing into a Faraday cage or Faraday Protection Unit (FPU) to protect them from the destructive effects of EMP.

Note: There is a two-part podcast series that explains all of this in great detail.  Be sure to listen to it by starting with the first part of EMP and EMP Protection.

Be sure to check out the videos I did that demonstrates shielding against a 50,000 watt AM signal, and the Surviving EMP Mini-Guide:

First, the items I list below might not be affected by an EMP if unprotected, but why take the chance? If there’s an electronic item that you deem important for your survival, then you should have it protected.

Second, you need to get your head wrapped around what life will be like without power and concentrate on storing those things that will give you a tactical and strategic advantage.

UPDATE 12-21-2017 – I’d like to clarify a point. When I say strategic advantage, what I mean is above and beyond where everyone else will be after an EMP. In particular, the advantage of electronic gear. Yes, having the basic knowledge and skills for a post-electrical world is critically important, but neither is a substitute for a pair of night vision goggles, or high-powered LED flashlights, or an electronic perimeter alarm system. These things give you a major tactical advantage over others who do not have these things. Other items give you a clear strategic advantage. There’s nothing wrong with planning on reverting to a 1800’s level of technology, and that should be your first goal. Just keep in mind, those with the tactical advantage usually win.

  • Things like radios, for both personal communications and gathering information.
    • For example, CB, FRS, GMRS, Ham and short-wave radios. The gear to do digital communications, like Digital HF, would be good, too.
    • A short-wave radio is important to hear broadcasts from other countries that weren’t affected by the EMP, as it may be a long time before there are any local news sources broadcasting.
  • Flashlights – What? you didn’t know that modern flashlights have electronics in them? If you have an LED flashlight, chances are that is has circuitry in it.
    • Not to mention, the LEDs themselves are very sensitive to EMP.
    • The old type of flashlights which are basically a battery-switch-incandescent bulb aren’t at risk.
  • Power generation equipment: generator parts, inverters, charge controllers, battery chargers, etc. It’s currently thought that solar panels would survive an EMP because there isn’t micro-circuitry in them.
    • However, if they are small, wrap them in foil and nest them inside a steel garbage can.
    • UPDATE September 1, 2012: I may have muddled this and want to clarify: we do not know for certain whether solar panels will survive an EMP, thus you should protect them like any other electronic device if your post-EMP plan relies on them.  See also my response to an EMP question here.
  • Repair parts for cars, trucks, tractors, ATVs, etc.
  • Night vision and other electronic optics.
  • Perimeter monitoring gear.
  • Computers (preferably laptops and tablets), PDAs, smartphones, ebook readers (Kindles, Nooks, etc.). If you have old stuff laying around, might as well as try to protect it. Don’t underestimate the force multiplier of having these things. Most of the tablet stuff (smart phones, iPads, Kindles and other ebook readers) are pretty rugged and will most likely last a long time. Imagine having the power of massive amounts of stored information at your fingertips.
    • Don’t forget to load these up with your survival info, documents and PDFs!  In addition to reference material, you should also put a lot of novels on these. Without TV or radio, reading will be a huge pastime.
    • Use USB thumb drives to store backups of your reference materials, books and photos. These are very rugged and are very easy to wrap in foil to protect.
    • Make sure that the small devices you have can be updated from the computers you have.  This is important in case they lose their info or you want to change the info.
    • On a similar note, WiFi components like wireless routers allow people to stay connected with these devices. This wouldn’t be at the top of my list of things to store, but if I had extra stuff laying around, why not protect it? It only costs a little foil and some space.
    • Ink-jet printer. Hey, why not. Printing information could be very important when the lights go out forever. Choose a printer that uses very common ink cartridges. Though you can store some of these cartridges, you should be able to find these readily, as no one is going to be needing them.
    • Many of these devices have internal batteries that need to be recharged fairly often. You’ll need to account for that and set up a schedule that allows for you to pull these out and recharge them on a regular basis.
    • One simple solution would be to export all of your preparedness and survival information as PDFs and store them on several USB flash drives.  An old, used PC laptop should be able to read these just fine.
  • Solar battery chargers – these are those complete kits with the charger and solar panel integrated.
  • Medical devices – if you have any electronic medical equipment, either for rendering aid or because you need it to live (blood testers, O2 machines, etc.), make sure to have spares.
  • Cordless tools – drills, saws, Dremel tools.
  • Calculators – solar calculators would be best, as they don’t need batteries.
  • Batteries – Although small batteries weren’t affected in the 1962 tests and car batteries seem to survive EMP testing, why take the chance? Put some in your FPU.
    • Energizer makes lithium batteries that have a long storage life.
    • Energizer Advanced Lithium will store 10 years, and Energizer Ultimate Lithium will store 15 years.
    • Even regular Alkaline batteries should have a shelf life of 5 – 7 years.
    • You can even store rechargeable batteries, though you should probably run them through a charge-discharge-charge cycle at least once per year.
  • SPEAKING OF BATTERIES – Make sure to remove the batteries from all gear before storage. There would be few feelings worse than opening your cache of EMP-proofed gear, only to find that the batteries that you forgot to take out had leaked and destroyed the equipment.
  • CFL or Compact Fluorescent Lights – If your home or retreat has its own power source and you plan on using CFL lights because of their efficiency, know that they have electronics in them to control the voltage to the tube. When not connected to a light socket, they’re probably not susceptible to EMP, but if your power plan requires these, then stick a bunch in a steel garbage can to be sure.
  • Update 12-21-2017 – LED bulbs and lights. These are much more common now than they were only a few years ago.
  • A Throw-Away set of equipment. Open this first to check on radio signals. Include some ear buds and batteries. Keep this in a separate Faraday protection unit, away from your main stuff. Of course, this is also good for other things that need power, too.
  • Have analogue backups for everything. GPS units are nice, but even if they worked after an EMP attack, the satellites will rapidly drift off course without constant correction from ground control.
    • Maps; compass; manual can opener; writing stuff like paper, pens, pencils; whistles instead of radios; candles and kerosene lanterns instead of battery operated and LED ones.
  • Not In Podcast– Some things that I’ve thought of after the podcast:
    • Multimeters, circuit testers, repair equipment.
    • Audio or music players, like MP3 players or iPods/iPhones, including any active speakers (speakers that have their own amplifiers).
    • Radiation meters – actually, these should be EMP proof already, but again, why take the chance?  At the very least, wrap them up in foil while they’re in storage.
    • Welders
    • Digital camera. Not really a high-priority, but could come in handy if you had a computer and were doing some recon.
    • Clocks – if you have old digital watches and clocks, why not put them in your Faraday cage? It would be better if you had a set of mechanical, wind up clocks and watches, but if you have the room, include the digital ones.
    • DVD players. If you have a lot of movies on DVD, might as well have a way to play them. But, you’ll also need something to play them on, like a small monitor, so you’ll need to store this, too.

This list is not prioritized, but you should prioritize your list before you start, as not everything on this list is necessary for survival. Those critical items, like medical devices needed to sustain life, power generation, flashlights, batteries and communication gear, would have the highest priority and should be protected first. Anything else that would give you an edge, like computers, night vision, powered scopes, perimeter monitoring, and items that make it possible to repair other items, should be the next highest on the list to protect.

Other things like DVD players, cameras, and handheld games should be the lowest priority. They’re nice to have, but not critical to your survival. That isn’t to say that you can’t have them, just concentrate on the needed items first. Just in case you run out of foil.

One note about storing electronics for use after an HEMP or CME event.

Keep in mind that without the infrastructure to make replacement parts and devices, what you have may be all you have. Ever. All the digital information that you have is to help you start a new life and give you an edge on learning all the new skills you’re going to need, now that there is no more electrical grid. Don’t plan on being able to access the information in digital format forever, or even for very long. If you don’t have paper backups of everything in your computers (and you should), then your post-HEMP/CME plan needs to include a way to start printing out all that info. Paper might be archaic in this digital age, but you can still read it after the power goes out.

Some Other Things To Consider About Post-EMP Conditions

Once people realize that the power is going to be off for a long time, possibly forever, things will probably get ugly and fairly soon. Be prepared to defend yourself and make sure you have all the needed items that go along with that (like magazines, slings, cleaning kits and plenty of ammo). Hopefully, at this point in the podcast, you’ve realized that as soon as we’re hit with an EMP, there won’t be anything made anymore.

If you are not living on your retreat property when it happens, you should have a plan that calls for you to bug out to it immediately. It will probably take 1, 2 maybe 3 days for people to realize how bad it’s going to be – use this time to get to the location that you plan on staying in. Since we don’t know what vehicles will survive an EMP, you’ll need a plan for acquiring one that still runs, but you can store the fuel you’ll need to get there now.

And, just to be clear, you need to have stocked up on everything. Because not only won’t there be anything made for long time, but once people realize how bad it is, it will likely become a dog eat dog world. To me, one of the best ways to get ready for this is to become part of a community, preferably one that can grow food and has access to clean water and natural resources, like trees.

It’s been said that an EMP attack would be like time-traveling the entire country back to the mid-1800s. But it will be worse than that. In the mid-1800s, we had people that knew how to grow food and make things by hand. We will have to re-learn those skills.

  2. Ethelyn says:

    Yes, but they also had horses, wagons, and commerce, even though it was slower than now.
    Also we must remember the ebola that is coming to add to the mix of panic and need. No one is mentioning the natural health necessary to address these problems and how/what is needed for that. Vitamins are not all. Herbs are the best and immunological.

  3. Janiemae says:

    My gosh, then how do you keep things charged up ready for use when ya need them. You put all of that stuff in a box to save you better be prepared to purchase this all again so you can continue to live, work, play and survive just daily life. These are all things we use, all the time. Not just once in a while or once a year or two. We are all electronically “hooked”. If I have to seal my radiation monitor in the cage, then what good is going to do me? When and if I need it, I will have to unseal the cage, which will contaminate all that is in the cage, dig thru to find the meter, and then see if I am contaminated. Gotta rethink this stuff. Might need several EMP cages all around everywhere. Thanks for the ideas though. Just opens up a whole new world of other options.

    • Rob Hanus says:

      Well, I think you should look further into EMP and radiation. EMP causes no radiation, though the reverse isn’t necessarily true. Batteries need to be recharged. Figure out a schedule that works for what you have and make it a part of your semiannual routine. You shouldn’t be allowing any of your preps to sit too long without inspection anyway.

  4. Janiemae says:

    The more I think about this, if you are prepping and preparing properly, then you are preparing to survive! Preparing to be without the biggest majority of this stuff. Cause if this does happen, these things are just useless stuff.

  5. Here’s how I’m surviving an EMP, preparing to live without electronics PERIOD. Learn NOW to live without should the need arise. It’s great to have electricity and all sorts of electronic devices at your disposal, but in my opinion, it also make’s you a target to those who lack those things and WANT them.

    As the article mentions, an EMP attack would throw us back to the 1800’s, and THAT is how you prepare, you learn NOW how people lived back then, you learn those skills, you practice them as much as possible. Ditch the tablet and kindle idea and stock up on REAL BOOKS.

    Yes, having a kindle or tablet filled to the brim with tons of information is great to have, especially if you have to be on the move, but the truth is, American today are NOT conditioned to hike long distances even carrying a kindle. And great, you got your kindle going along with you on your journey.. What about food? Water? Do you have the endurance to lug along a weeks worth of both? Do you know how to procure it from the wild if necessary? Do you know what plants are safe to eat? Do you know how to clean and dress animals you’ve hunted/trapped? Do you know how to make water safe to drink?

    Carrying your kindle with you and ‘learning’ on the run is DUMB, you’re going to be dead in a week. Most people don’t have a bug out location, if you’re home is compromised, then what? Where do you go? Run to the hills with the thousands of other’s who had the same stroke of “genius” to live off the land after the read how on their kindle or watched a couple downloaded youtube clips on their tablet?

    The author is correct, information is POWER and that POWER is needed NOW, not after the fact. Prep with your brain, not with stuff. Learn to build, learn to make things by hand, learn to hunt and forage, even learn to eat insects. The more primitive in mindset and skills you can get, the GREATER your chances of surviving an EMP is going to be. Get to a point where you can go on a week long ‘camping’ trip into the woods with nothing but a good knife.

    The industrialization of civilization has weakened the human intellect and body, once you break that bond, only then do you have a chance of survival.

  6. Also, read One Second After, EXCELLENT book on the reality of an EMP attack!

    • Oregon Gracie says:

      Excellent book, One Second After… recommended read if you are serious about this topic. I agree with simplifying and accepting life will be better with NO electricity or electronics. Non-hybrid seeds will be much more valuable and better weight to carry when hiking, rather than a kindle. Think organic, natural and holistic. Live like the Amish – better sooner than later… my two cents.

  7. Gloria says:

    Think about bicycles with basket or paniers, tools, hand tire pump, inner tube replacements and yes of course a heavy duty lock.

  10. Michael says:

    “Repair parts for cars, trucks, tractors, ATVs,” I am not a mechanic. i would like to ask what specific electronic components there are from vehicles (cars, planes, boats, etc) that are vulnerable to an EMP attack. Also, is there an organized network of preppers which could share responsibility for storing high value items which could be used in rebuilding, such as parts for trains, trucks, factory machinery,etc.?

    • Rob Hanus says:

      That’s a difficult question to answer. For one, I have no idea which parts are susceptible and which aren’t susceptible to EMP. Secondly, I have no idea which specific vehicles you’re referring to. However, even if I did, it’s really beyond my ability to answer this for you. You’ll need to do your own research and determine which parts you need to store.

  11. Karen Arruda says:

    Where can I find a group of like-minded people?

  12. Renato Tambellini says:

    Solar panels have a junction box with 3 diodes that increases the energy efficiency and may be damaged during the normal use. I don’t know if another parts can survive an EMP event, but this component certainly not and fortunately it can be replaced. So a good practice when using solar panels would be to store one or more junction boxes into the Faraday’s cage.

  13. Diana Neri says:

    hi, and thanks for useful list; however am confused: you keep saying wrap things in foil. but shouldn’t I wrap them in something to insulate them from the foil first? otherwise am I not just making them a more attractive surge atractor!

  14. Pedro V says:

    I’m curious if anyone has thought of using a old refrigerator as a faraday cage, with it’s corners /seams sealed with foil tape? And which vehicles are least likely to get zapped? Or is there a way to protect your vehicle again from being zapped?
    And would a external hard drive be a good save?
    Any suggestions or ideas is better than none.

  15. Ryan says:

    If you build your own faraday cage, you need to constantly keep opening it to change out batteries, let things recharge, and things like that? So don’t just seal it up and leave it, you have to keep reopening, taking care of everything, then resealing?

  16. What should you keep stashed away in case there is a total blackout? Sometimes we get so used to having electricity around that we simply cannot picture ourselves without it. Also, batteries are slowly becoming a thing of the past, unless maybe you want to travel. It is a good thing that this article gives you an extensive list of the things that you should keep in a faraday cage, and this way you will not leave anything out. While some people might think of entertainment and communication first, things like a digital camera and night vision devices might come in handy

    • Rob Hanus says:

      Total blackout? Whether caused by EMP or not, the same list of gear would apply.

      Batteries a thing of the past? Not really. Batteries are in just about everything and the technology has improved greatly over the last few years and we continue to make strides in battery tech. If you haven’t upgraded your rechargeable batteries and chargers lately, you should look into doing so.

  17. Don M says:

    Harbor Freight sells a simple and economical ($25 and $14) Faraday cage (aka aluminum tool case) in 2 sizes (18″ x 13″ x 6″ and a smaller one). It is all aluminum with doubled edges and corners, insulated inside and, best of all, the hinged lid is constructed as a male/female aluminum-to-aluminum engagement around the entire case.. (picture a tongue and groove joint). Handy size, easy to access contents, no need for foil tape, light, and portable…

    • Rob Hanus says:

      Hmm… you would need to test it (as described on this site). Looking at the pictures of these cases, they have rubber or plastic on the corners, making for an entry point of RF (EMP). The are also pretty thin. I’d put foil tape around the edges and test when sealed. My guess is this might make a good inner box, but probably not going to be good for the only layer of EMP protection.
