Anonymous Coward User ID: 573835 Canada 10/10/2009 11:55 AM Report Abusive Post Report Copyright Violation | Personal Protection Steps Against EMP What can your everyday civilian do to protect themselves against the possibility of an EMT attack? 1. Have a lot of battery operated devices on hand and the batteries to use them. Further, these appliances should have cords and antennas 30 inches or less in length. The reason for this is simple: Metal pulls in EMP and makes it more dangerous. Thus, less metal is good. Further, keep these appliances away from metal. 2. Stay 8 feet from large scale metal fixtures yourself. In fact, when EMP is concentrated by metal it can actually be dangerous to man in and of itself. 3. Harden your equipment (another way of saying, protect it from EMP). Some considerations include the use of tree formation circuits (not standard loop formations), induction shielding around components, self-contained battery packs, loop antennas, and Zener diodes. In addition, grounding wires for each separate instrument into a system could help as well. 4. A new device called the Ovonic Threshold Device (Energy Conversion Devices of Troy, MI) is a solid state switch that opens a path to ground when a massive surge of EMP is encountered by a circuit. This would help in a big way. 5. Use a Faraday Box to store equipment in. Makeshift Faraday boxes can be made from metal filing cabinets, ammunition containers, and cake boxes. That said, the device you are protecting must not touch the metal container (use insulation: paper, cardboard, whatever). Further, there can be no holes. Last, if the box seems less than adequate, you may wrap it in aluminum foil for more protection. 6. Wrap your rooms in aluminum foil. Well, it's certainly extreme, but thought it worth mentioning. After you do so, cover it with some type of fake wood, etc. [Some drywall boards have a metal sheet, so select such boards when remodelling] 7. Cars are already a metal box. Thus, most of them would survive. That said, gas would be a problem. So have a lot of that and food on hand (remember that refrigerators and water sanitizing devices would go out). Only the EMP from a near hit surface burst can cause trouble for hardened silo. 156 kA, 56 kA secondary peak. Lightning up to 1km distance generated from a 10 megaton blast. The peak electric field from Starfish prime (1.4 megaton blast) on Honolulu would have been 5.6 kV/m energy density 0.01j/m**2 [This is 10% of the worst case field, so there is high variability in the EMP effect] The US would be able to launch nukes from silos, bombers and submarines after any EMP attack. |
BadJack (OP) User ID: 790206 United States 10/10/2009 12:05 PM Report Abusive Post Report Copyright Violation | This from the article: First of all, allow me to dispel some myths about Faraday cages—and boy, howdy, there are a LOT of them. Whether or not your electronics are plugged in, how long of an antenna you’ve got on something, what voltage it is, or whether or not they operate with batteries—all non-protected electronics will be affected by an EMP. Batteries will be affected, usually in the form of “shorting” as well. Electronic phone systems will also be damaged. Surge protectors are useless in the event of an EMP exposure. Just because your car has rubber tires, it will not be impervious to the effects of an EMP. Rubber containers are insufficient protection against an EMP. And oh yeah—yes, your Faraday cages DO need to be grounded. If it’s NOT grounded, then the Faraday cage merely becomes a reflector or an amplifier. Yes, a microwave can act as a Faraday cage, but why in the world would you want to use it for that? That’s just silly when you can make one simply. Faraday cages do not have to be solid, thus the name “cage” instead of the oft misused term—“box.” In fact, many of them that you can build yourself or will see on the internet will resemble a bird cage or a very finely meshed chicken coop wire. Copper Mesh photo c/o twpinc.com Also, contrary to what you may see on the internet, a sheet of foil on a box will not protect you. It’s not thick enough to withstand the pulse. However, you CAN protect your items if they are buried a couple of feet underground in every direction (up and sideways.) Last, but not least, a car is NOT a Faraday cage sufficient to withstand an EMP incident. It has some similar components, yes. Most cars made today consist of fiberglass and disjointed parts, not a continuous metal material. In addition to that, they are on tires. Tires on a car do NOT serve as grounding. Folks are simply getting an EMP strike confused with a lightening strike. Now, IF you had an old fashioned car that was made of metal, that had its tires removed, that was also attached to an Iron or copper pole and that was ALSO on dirt—not gravel—then yes, you may have a car that doubles as a Faraday cage. (Kind of like the old clunker my dad has out in his “back forty.” The cages do not have to be solid, but they do have to be constructed continuously without gaps between the protective material. |

Just need to save a battery. Some walkie talkies too. Quoting: BadJack 790206Don't older cars have a selenoid for the starter and an ignition coil? I wonder if they would be affected.. |
