Your electrical devices must be protected form any EMP attack which is caused by the electromagnetic pulse. Being a victim of a nuclear or nun-nuclear EMP attack form an unfriendly country would give a great real threat. The detonation of a nuclear bomb from 25 to 250 miles above the horizon line will disturbed the magnetic field lines of the earth due to massive pulse of x-rays and gamma radiation-containing photons. The electrons trapped in the field lines of the earth causes a dangerous fluctuating electric current that 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 had studied weaknesses in the military as well as the civilian sector and made recommendations of methods to protect the United States from the EMP threat. 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 any EMP Protection, any country and anyone will experience disruption. Disruptions can be seen in vehicle engines, all communication systems, industrial equipment, water pumping systems and electrical appliances and grid. Another scenario would be airplane ignition systems causing in-flight planes to fall out of the sky. The EMP attack will likely to be followed by a downfall of the infrastructure. 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. 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. Metal filing cabinets work well too as long as the devices you are protecting does not come into contact with the metal cabinet. The aluminum foul can be used in protecting your own devices from the disruption but you must wrap it with plastic first before wrapping it with two or three layers of the aluminum oil. 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.
