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. The electrons trapped in the field lines of the earth causes a dangerous fluctuating electric current that 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.. 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.
Having no EMP Protection, the United States and any other country can experience disruption. The disruption will be evident in all communication systems, vehicle engines, 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. 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.
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. 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. This will disable communication thus putting everyone in a hard situation.
