EMP THREAT FACT
False. In order for the steel shelter hull to provide EMP shielding, all the POE’s or “points of entry” must have a copper or nickel shielded gasket specifically designed for EMP with a dB rated gasket for the H-Field, E-Field, and Plane Wave. This means that EMP shielded gaskets are needed on hatches at ground level, emergency escapes entranceways connecting to the hull, air inlet ducts, air outlet ducts, electrical lines penetrating the hull, water lines penetrating the hull, antenna wires penetrating the hull, video cables penetrating the hull etc. In a steel hull, whether made of galvanized culvert or straight wall steel tank, all of the POE’s require monthly testing because the hull is constantly corroding. Testing requires very special equipment and personnel. The golden rule for EMP shielding, that the military has followed for many years, is “DO NOT USE THE SHELTER HULL AS AN EMP SHIELD AND DO NOT USE THE EMP SHIELD AS A SHELTER.” The best approach for EMP protection is to shield each EMP vulnerable item individually inside the shelter because EMP shielded enclosures can be tested and are made of non-corrosive material. Proper EMP shielded enclosures are not made of steel because it is not conductive enough. A proper EMP shielded enclosure is made of aluminum which is 5 times more conductive than steel or copper which is 8.5 times more conductive than steel. Aluminum foil does not shield EMP frequencies. Radios can be disconnected prior to a disaster event but all inverters and chargers, solar charge controllers, solar panels, and most generators need EMP shielded enclosures.
