5 Ways to Prepare for an EMP

It’s all in the news. North Korea has their finger on the button. Even though they have been saying that since the Korean conflict in the 50’s, it seems much more plausible now. If they or any other country does decide to deploy a nuclear weapon against the U.S., there is good chance it will be an EMP. That stands for Electro-Magnetic Pulse. When a nuclear bomb detonates, there is a blast radius that levels everything in its path for a limited number of miles. Then comes an electro-magenetic pulse. That wave extends much farther and fries all electronic circuitry that is not protected. It is possible an EMP would render anything with a circuit board completely useless. That includes modern cars, computers, radios, TVs, cell phones, and, well, you get the idea. It would affect almost everything we use in our daily lives. Lives would come to a stand-still in the area affected by the EMP wave. It would not harm human tissue, just all circuit boards. Some argue that the circuit board has to be powered on at the time of the blast for it be destroyed. If so, it would still take down all moving cars, all running computers, and all cell phones. Same end result. Everything stops. Many stress that the biggest threat is to our national electric power grid. If that goes down, all electric utility power is gone.Nuclear EMP

Another form of EMP is caused by a solar storm. If the sun has a large Coronal Mass Ejection (CME, a severe solar flare), it could cause an EMP wave to hit whatever side of the Earth it is facing. The results may be similar to a nuke EMP, but could affect a much larger area.

Looking Up

An EMP deployed in the atmosphere would have a much larger affect than one on the ground. In this case, the nuclear detonation occurs well off the ground. The initial blast is harmless, the EMP propagates much farther, and the radiation cloud disperses somewhat and gets carried farther. The EMP reach is so much larger, it may even be possible to take out the entire Eastern seaboard of the U.S. with one atmospheric EMP. There are various theories on how the radiation will disperse. I’m expecting the prevailing wind and weather to have an impact.

How do you prepare for such an event?

Here are 5 steps:

(adsbygoogle = window.adsbygoogle || []).push({});

#1: Read All About It

So far, I’ve read 3 full novels about the disaster following the detonation of an EMP. Note that they are all fiction and represent the author’s beliefs on what could happen. Call BS as you see fit, but they are thought-provoking!

  • Book 1: One Second After by William R. Forstchen: This book started serious prepping for me and other family members. It was so pivotal for me, I actually blogged about that book HERE. Looks like there are 2 sequels now.
  • Book 2: A Distant Eden by Lloyd Tackitt. This is very easy read and ended up as a 7 book series. I read the first 5. In this book, a solar storm caused  the EMP.
  • Book 3: Trackers by Nicholas Sansbury Smith. An interesting take on rural impacts. The plot here is less directly about the EMP, but still interesting. Has 3 sequels.

#2: Situation and Position Awareness

First off, know the signs of an EMP happening. If your phone suddenly stops working, check with someone else to see if theirs stopped too. If everyone’s car just turns off, it would obviously be an EMP. Second, know exactly what to do next. Most people will be standing around wondering what to do. You will be calm and collected while you swing into action. Be aware of your surroundings and how they would help or harm in the event of an EMP. Are you in a crowded city? How far away from home are you? How dependent are you on infrastructure, specifically the power grid? Envision how you would handle the event while answering those questions. Then just prepare ahead of time so that the answers to those questions are acceptable.

#3: Start by Preparing Just Like For Other Events

Before an EMP has occurred, much of the preparation should be similar to other prepper events. Basically, get to your bug-out/bug-in location, secure your food and water, watch for the 2nd or 3rd day run on grocery and hardware stores, watch for the 1-2 week widespread panic, etc. The unique aspects of an EMP are as follows:

  • Acknowledge that this will be a long-term (maybe permanent) situation
  • Expect no help from the government. Expect no public electric power.
  • Protect electronics (#4 below)
  • Prepare to monitor and respond to the radiation dispersal (#5 below)

#4: Harden Important Devices

There are ways to protect sensitive electronics. It is called “Hardening” and makes it so the pulse is not passed on to sensitive electronics. The most prevalent is called a Faraday Cage. You actually probably already have one in your house. If you look at a microwave oven door, you will see a metal mesh in-between the glass. Also notice that the seal around the door is metal. This is a Faraday Cage meant to keep harmful microwaves inside the oven. You can use the same concept to keep an EMP out! One way to do this is simply to store electronics in an old microwave. I use a filing cabinet with foam lining so nothing is touching or near the metal. I keep charged radios in there so I can listen and find out what is happening after an EMP. Some recommend galvanized trash cans. If you wrap something in plastic, then aluminum foil, then plastic, and a second layer of foil, that should EMP-proof it too. I do that with spare fuses for my car (in the event that the car fuses take the hit and the rest of the circuits survive). Theoretically, if you ground your Faraday Cage (connect a wire that runs to a good ground), that should shunt the pulse to ground better. See your local Ham radio operator for more details.

#5: Get a Geiger Counter

Seriously? People buy Geiger counters? Yes, or you won’t know you’re being exposed to deadly radiation. The device is I use is technically called a radiation detector. It is called NukAlert and you can get it HERE on Amazon. It is not cheap but last for 10+ years and could literally save your life. I attach it to my everywhere carry bag using a Grimlock. It will start chirping if you get exposed to radiation. It is the only way to know when and where the radiation cloud occurs. If it goes off, determine the wind pattern and go the other way. It would also be helpful if you live anywhere near a nuclear power plant that goes hot.

The Final Word

I hope these steps will help you prepare for the possibility of an EMP. Remember the #1 rule before, during, and after any event: Don’t Panic. By planning ahead, you will be more prepared than most and ready to handle whatever happens. If you are an EMP fanatic, let me know if I left anything out.

Be safe by being smart,

    An EMP over the West coast could be a probable event, if that figure skating power house, North Korea, launches a weapon. It could take out some or most of the West coast. So? Well, that would bring shipping to a halt. Cargo transfer would stop. Ships would not be able to unload. Ships at sea, may have to turn back. If they can still navigate. Chinese ships, in China, would have to stop loading. The Chinese factories would have to close and layoff workers. There are a few other reasons to disarm KJU, but, this might be the biggest.

    So, I think, the Chinese could take out take out KJU, if they had to. There are a few other reasons to disarm KJU, but, this might be the biggest. But, I still have my Faraday cage.

      Thanks for the comment! One book I read said it would take only 3 EMPs to take out the entire U.S.

    A microwave oven is designed to contain a very narrow range of radiowaves near the 12.23 centimeter wavelength and 2.45 Ghz frequency. Basically, a microwave oven used as a Faraday cage will only protect your equipment from another microwave oven. The steel cabinet offers a little additional protection but the oven has an electrical cord which will act as an antenna which will direct more of the EMP energy into it.. Build a proper Faraday cage and forget about the microwave.

      Wow, thanks for this great correction! I’m guessing not many people have an old microwave laying around anyway.

    Don’t ditch the microwave as it can successfully be used as a water tight container as can your dishwasher.

      Marilyn, WHAT?!? I know you can’t be serious..but I don’t get your joke! microwaves are NOT water tight.

        I agree. I’ve never heard of a water tight microwave. I have heard that a dishwasher will keep valuables dry in a flood.

    Note that the CDC has scheduled a meeting on January 16, 2018 to figure out how to handle a nuclear detonation in the United States. Also, the U.S territory of Guam has issued several fact sheets telling people what to do if North Korea bombs them. This link will take to the fact sheets: http://www.ghs.guam.gov/.

    What good does it do to harden electronic/electrical devices, if the grid goes down for a very long time? I think you should have added a 6th item, have an alternative source of power, such as an off-grid solar electric system, with sensitive components of that system stored in a Faraday Cage.

      Thanks for the question. I plan on two phases of a disaster: short term and long term. The faraday cage is for the short term with the only goal of using my radios to listen for any news on what has just happened. I don’t expect the batteries to last long. In the long term, a solar electric system would help provide power, but it is expensive and difficult to shield. If you did this (and I have before), you would need a good cage around the charge controller and a good grounding system. Be safe, FJ

    Farrell Kingsley writes several really good books on EMP’s also. Nine Meals To Anarchy Series. I really liked those and have read all the books listed above also. Underground or a faraday cage! Yes!

    very good article I truly didn’t know there were so many ways to prepare with just house hold items for emp protection. Very interesting.
