Preparing For an EMP The Dangers and PrecautionsThere are quite a few misconceptions about EMP’s and what exactly we need to do to prepare for an event like this. This is also an area of preparedness that most of us are lacking in. With our dependency on technology today coupled with our ailing infrastructure and a power grid that is basically temporary.

In this article from they state the following about the power grid:

The fact that the electric power grid began as a convenience, but has become a necessity for sustaining life, is both one of the most beneficial, and one of the most dangerous, facts of 21st century existence.

We do not know how long the current power grid will last; but if it not replaced by a robust permanent infrastructure in time, hundreds of millions of people will die when the electric power grid collapses simultaneously in many countries.

How such a collapse occurs is very well known, and the methods to either prevent it, or to have spare transformers in place to fairly quickly repair it, are also well known.   Although these preventive measures would not be terribly expensive, they would take some time to put into place; and those things have never been done.

This is a great article and I will be siting it periodically in this article, it is pretty long so you might want to bookmark it, but it’s worth the read and has everything that you need to know about preparing for an EMP, the dangers and the Precautions you can take.

PREP DRILL! What Would You Do?

Prep Drill What is your planAs you’re sitting there watching your favorite news program your TV suddenly shuts off along with the lights and everything else in the house. You grab your phone to check if you forgot to pay the bill, and that doesn’t work either.

You head outside and see that there is no power anywhere, the street lights are out, your neighbors are walking around looking confused and even the cars in the streets are not moving.

At this point you know that some sort of EMP caused this and you decide to check your car to see if it will start…Will it?

What is your plan? You’re not sure what caused the EMP but you know everything is about to get way out of hand and time is of the essence.

I recently posed this question to our Facebook group and the answers were fantastic and very enlightening. They ranges from going out and buying everything you can as quickly as possible to bugging in and finding out who is going to be with you, and who you should protect yourself against.

I will go into more detail about these responses in the next podcast, but for now lets talk about the difference between an EMP and a CME.

Nuclear EMP vs CME

EMP ZonesIt’s important to understand that there is a difference between an EMP (Electric magnetic Pulse) and a CME (Coronal Mass Ejection) or solar flare. Both can do massive damage, but what they will damage is different.

A Nuclear EMP device is designed to deliver 100 to 200 Kilovolts per meter. This is a massive and destructive blast of energy but is more localized than a CME. The Maximum Electronic Destruction (MED) is shaped like a smiley face.

The geographic size of the MED is determined by the altitude of a NEMP (Near Earth Magnetic Pulse) detonation, and if you happen to be in the not so funny smiley face (Maximum Electronic Destruction zone) there is not much if anything you can do about it. From surge protectors to faraday cages, nothing will prevent total destruction of all electrical devices, your phone and your toaster will be toast.

Because most of us (hopefully) will live outside the MED zone Faraday cages and surge protectors are good to have to protect some of your more important electrical devices. The article from Future Science also goes through what makes a good faraday cage and other techniques to protect your electronics.

A coronal Mass Ejection (CME) despite popular opinion will not render your car useless because the electrical system is fried, but it could be rendered useless because the gas stations will not have power. How much fuel do you have stored?

The dangers of a CME are the affects it will have on the power grid, and everything that will happen because of our dependence on the grid. Everything we do requires electricity in some way or another, from food getting to the grocery store, to fuel getting to the gas station.

The last (large) CME to hit the earth was the Carrington event back in 1859, Scientist estimate that this happens every 150 to 200 years. The Carrington event happened 155 years ago which puts us right in the danger zone, although in 1921 a large solar storm, of briefer duration than the 1859 event, occurred which affected a much smaller area of the planet.

EMP Precautions

Equipment Protection: Whether or not your electronics become fried really depends on the severity of the situation and whether it was a CME or an EPM. It’s always a good idea to at the very least have surge protectors installed and even you’re most important electronics stored in a faraday cage or electromagnetic shield.

Faraday cages are not absolutely necessary for solar flares, but it never hurts to be safe and store some smaller items like a shortwave radio, a tablet, phone or even an old laptop you have digital information stored on protected.

Check all Vehicles and Electronics: Check everything, Cars, phones, computers, lights, generators and anything you have that could be useful in the coming months and possibly more.

Take an inventory of your equipment including everything you have that is not electronic. What you actually have and what you think you have could be two different things. What you don’t have you will need to go out and get as quickly as possible.

Spend your money: This is a major reason for having cash on hand. The ATM’s will be out of order and everything you have in the bank will be gone for all intents and purposes.

Money will lose its value very quickly, and available supplies will disappear even quicker. It’s time to take advantage of being a prepper, you know more than the average person how this is going to turn out so get what you can while you can.

Your security Plan: Just about everyone who commented on the Prep Drill said they would bug in because there was really no benefit to bugging out. I tend to agree unless you have you bug out location ready to go.

If you do choose to bug in have a plan in place if things go from bad to worse. Having windows and doors locked and barricaded might seem like overkill in the beginning, but eventually the supplies will run out and so will everyone patience.

Make sure everyone in your home knows the plan and how to react to certain situations. If you have family in different areas have a plan for everyone to be in one place.

Fill Everything With Water: Take every opportunity you can to collect water, even if it means just the residual water you can get out of the pipes. Having water already stored is a good head start, but that water will only last so long.

This is an area we are lacking, we have water stored, but I still haven’t installed a manual well pump. I am currently saving the money to get an Earth Straw and I am hoping nothing like this happens before I get the opportunity.

Communications: Depending on the situation and the severity of the damage you will want to get information about the situation as quickly as possible. An NOAA Radio that has been stored in a faraday cage or is unaffected could give you information about how wide spread the problem is.

A short wave radio could help if the entire United States grid was down and you needed to get information from other countries that were not affected.

HAM radio could be affective if you know the right channels and your equipment is unaffected. This is another area I am lacking in, I have my technician’s license, but I haven’t done enough to make this a valuable tool…I’m getting there.

Consider Hygiene issues: As the weeks and months go on trash and waste will become an issue. Consider what you are going to do with human waste, consider what you will do with the trash that piles up and consider what everyone else is doing with their waste and trash.

Bad hygiene and unsanitary conditions can lead to sickness and death, most people won’t even give this a second though until the smell becomes too unbearable to handle.

Work with your neighbors: I have read conflicting ideas on this, but it’s my opinion that if you can prepare your neighbors, they become less of a threat to you.

There is power in numbers and while you should not disclose everything you have, you should try to get a better perspective about what skills and resources your neighbors have and try to pull them to your side, rather than the dark side.

Don’t underestimate the situation

Most people will be scurrying around dazed and confused about the situation. These people will be waiting for the power to magically come back on. Underestimating the situation will be dangerous because it gives a false sense of security and the more action we take initially will help us down the road.

There are a lot of things we can try to be 100% prepared for, and a lot of things that regardless how much we prepare times are going to be rough. An electric grid failure is one of these things. The failure of the grid from an EMP or a solar flare will only be the first domino to fall, the events following will be chaotic and dangerous to say the least…but this is why we prepare right?

Make sure and read the article from and also this one from Both have a ton of information and will give you a better idea how to prepare for an EMP or CME.

What would you do?

Leave us a comment below about what your plan of action would be and I might read it on the Surviving Monday’s podcast.




Survival and being prepared should not only be a passion, it should be a lifestyle. The definition of a prepper is "An individual or group that prepares or makes preparations in advance of, or prior to, any change in normal circumstances, without substantial resources from outside sources" Like the Government, police etc. I don't believe that the end of the world will be the "end of the world" I believe it will be the end of the world as we know it now.

      Wish someone that really knew about EMP/CME would elaborate on the best techniques for protecting garaged vehicles and communication equipment openly being used within a home. DIY, put it in a plastic container and then withing a trash can buried in the back yard is not reticent to being able to use it when needed. A large microwave oven seems to work the best for me, but I still have my doubts on its effectiveness. Can a single windowless storage room be given ample protection using DIY products? I read a ton of info on what an EMP/CME will do, but not much on how best to protect from it.

        Thanks for the comment methane, the article I linked to from Future Science has a ton of information about protecting your electronics, what works and what doesn’t. It’s a long article, but worth the read.

          GO TO THE HARDWARE STORE,and buy a LARGE metal trash can,line them with carpet pad,rap all the electronics with aluimiun foil,and put them in the trash can,and seal the LID with aluimiun duct tape 2 inches wide,and your electronics will be safe,BUT what about my car? go to you pull it auto parts wrecking yard and buy spare computer,coil,and distributor pickup moduls, IF your car is to high tech,your screwed….IT’LL make a nice yard decoration,THE LORD says THREE EMP’S, one over the east coast,one over the west coast and one over nebraska,on the 22nd,of the month,he just didn’t say what month,or year,and that was last year,ask him maybe he’ll tell you and you can tell us…………….

      Excellent article. Other tips:

      1. Set up a battery powered alarm for when the electricity goes off. It could be 3am and the advance notice can save your life.I

      2. If bugging in, begin water collection immediately. Just sticking new garbage bags open over 4 sticks repeatedly all over the yard will produce several gallons of water.

      3. If bugging in, the solar powered yard light sticks are cheap at Lowes and Walmart. Tie a rope to them and sling them over tree limbs and light poles to backlight your perimeter.

      I wood start to do right now is look up how to build a Faraday cage. For amateur radio(ham radio) look at getting a kit radio(one that is not built already) and have the tools to put it together.

      HERES what the military is saying,THE PEOPLE are divided into three groups,THE RUNNERS,THE HIDE INS,and THE FIGHTERS,,,,which are you?IF your planning to stay home,your screwed before you get started,their going DOOR to DOOR and tear apart every home,looking for hiders,and they better not find you,OR YOU’LL BE SHOT on the spot………BE smart,find a place in the mountains and stash your gear there,then when the asteroid hits,head for the hills………look at rubys table talk,she’ll tell you all about it…………….

      You need to read One Second After! It will show you the horrors that await if this happens. I’m prepped to the hilt with food and guns. However, I can’t feed everyone and there are people with more guns than me!

      I have a small seed bank for next year’s crops. However, I DON’T rely on food from the forest – of course I’ll hunt and fish but 3 million other people in CT will do the same thing – won’t take long and the forest will be empty of food and filled with fools.
