EMP (Electromagnetic pulse) is a subject I am always trying to find out more about. Now I am not going to become an expert in electronics, but I want to know enough to protect my electronic devices. Now I do not think that I can protect my whole home or even large devices like my refrigerator. They are on their own and will survive or not. However, there are many smaller items that I want to survive.
Facts About EMP’s and CMP’s
Now I know that there are some differences in the type of pulse that is given off by CMP (coronal magnetic pulse) and EMP. I believe that the damage caused by EMP would be worse than CMP. The E3 pulse from a CMP will last much longer and can last for days. The E3 pulse will affect long distance transmission lines, but probably won’t affect your small electronics. An E1 pulse is very short but will affect transmission lines and small electronics. My plans to protect my equipment are base on the E1 pulse from a nuclear blast.
I have been getting information from an electronic engineer that has been doing some testing on EMP. One of the things that he has tested is the difference between the different types of galvanized trashcans. He recommends that we use the locking lid container manufactured by Behrens for Faraday cages. This is trash container that is made of good steel in the US.
I purchased the ten-gallon one to evaluate and am very impressed. I have never seen a trash can lid fit as tight as this one. Then when you put the handle in the upright position, the lid is locked on.
Mine was purchased from Amazon Prime and was definitely reasonable. I have been told that this brand can be bought at Home Depot. After getting mine, I cut up the box it came in and used it to line the can. I then placed a plastic garbage bag inside for extra protection. The container was then filled with small electronics that I want to protect.
I have other faraday cages, but some of them are hard to get into and I use some of these items often, so this can works well. In the future, I may consider wrapping some of the contents in plastic and then aluminum foil for extra protection.
This can is impressive, it is the best I have seen.
Now that I’ve read this article, I may have to get a couple more of them. The one we originally bought two years ago, we just use for cleaning the fireplace.
Thanks!
I use the exact same Behrens can for my Faraday cage. It works like a charm! Blocks phone and radio signals!

Won’t the holes for the handles make it useless for a faraday cage?
Ther are no holes, the can is tight.

Aluminum tape wrapped around the lid gap adds extra protection at the most vulnerable area.
Aluminum tape is adhesive backed and thus not electrically connected to the garbage can. I seriously wonder if it helping as much a it looks.
You might consider wrapping it adhesive side out (so aluminum is touching can) and tape edges of aluminum foil with scotch tape.
Or you could actually read about the tape and make sure you are buying metal tape with conductive adhesive.

I plan to use a shipping container for my bug out location. What about lining it and using it as my faraday cage as well? Does anyone have any ideas on this possibility?
Lyn,
Have you gotten any replys to your shipping container used as a faraday cage?
Can you recycle cans (keep the lid once removed)to store electronics and seal with aluminum tape?
I think it would be questionable. At least wrap the electronics in aluminum foil and then place in the cans, sealing them well with the tape
would a spray rubber lined metal garbage can work well as an EMP protection container?
Don’t metal cans need grounding?
That’s been a controversial point for a long time. I’ve found Arthur T. Bradley to be a reliable source of information related to EMP and Faraday containers. His verdict is that Faraday containers do not need to be grounded.
