To protect your electrical devices from any EMP attack means you will have to safeguard it from the effects caused by electromagnetic pulse. Being a victim of a nuclear or nun-nuclear EMP attack form an unfriendly country would give a great real threat. Following the detonation of a nuclear bomb from 25 to 250 miles above the horizon line, the magnetic field lines of the earth would be interrupted by a massive pulse of x-rays and gamma radiation-containing photons. 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 threat being imposed by an EMP attack is alarming that the House Military Research and Development Subcommittee and the House National Security Committee created the Graham Commission.. The committee is intended to know the weakness in the military as well as in the civilian sector and recommends such methods to improve the protection ways to the United States from any EMP threat. The Graham Commission is entitled to recommend storing electrical grid components and any hard to make devices which are needed to keep it at work.
Having no EMP Protection, the United States and any other country can 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. A breakdown in the infrastructure will likely to occur following an EMP attack. Comparing the effect of disruption to house built of cards when one supporting card is pulled out, its effect to any electronic infrastructure would also be the reason that it would crash down in a split of seconds.
You can possibly protect you own devices from any disruption by storing them in containers which is made from aluminum and copper. These protected devices can possibly resist these electromagnetic pulse effects. The galvanized metal trash can is being insulated with a thick cardboard which make it a great and high quality EMP shelter. Moreover, you can store your own devices to a metal filing cabinet as long as the devices do not come into contact with the metal cabinet. 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. EMP protection also means you have to have enough food, water, and medical supplies for your family to survive any shortages and social breakdown. 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.
