Protecting your electrical devices from an EMP attack means you will have to take precaution from the effects of electromagnetic pulse. Being a victim of a nuclear or nun-nuclear EMP attack form an unfriendly country would give a great real threat. The magnetic field lines of the earth can be disrupted brought by a massive pulse of x-rays and gamma radiation-containing photons caused by the detonation of a nuclear bomb from a 25 to 250 miles above the horizon line. Electrons which are trapped in the field lines of the earth would cause a dangerous fluctuating electric current which is capable of disabling electronic equipment.
The real threat of an EMP attack is so high that the House Military Research and Development Subcommittee and the House National Security Committee have created the Graham Commission.. This committee has been aiding the military to seek improvement and strengthen the military as well as the civilian sector. The Graham Commission is recommending to store any electrical grid component and nay hard to make devices that are necessary to keep it working.
Without proper EMP protection, the United States would experience disruption. Example scenarios would be: Vehicle engines, all communication systems, industrial equipment, water pumping systems and electrical appliances and grid. Airplane ignition systems causing in-flight planes to fall out of the sky can also be affected by the disruption. Following an EMP attack, a rapid and complete collapse of our infrastructure would happen. The electronic infrastructure will possibly crash down in seconds like a house built of cards when one supporting card is pulled out if disruption occurs.
To ensure safety for your own devices, you can keep them in containers which are mainly made form aluminum and copper. Your own protected devices will be able to resist the effect caused by electromagnetic pulse. There is a galvanized metal trash can which is basically insulted like thick cardboard that makes it a great and of high quality EMP shelter. Also, metal filing cabinets can be a good storage to your devices that you are protecting as long as the devices do not get in contact with the metal cabinets. You can use aluminum foil in protecting your own devices by wrapping it around the smaller electronic devices but first it must be wrapped by a plastic first then you can wrap the aluminum foil having a two or three more layers. This MEP Protection only means that you must have enough supply like food, water, and medical supplies for your family to survive from the aftereffect of disruption. The inability to communicate while the government tries to restore power will look like a war zone scene on TV as people suffer from lack of drinkable water and good food.
