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 cost me about $22 including tax. 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.
