Strategies for protecting electronics during an EMP event?

EMP-Hardened Equipment Selection

When selecting EMP-hardened equipment, look for devices with built-in surge protectors or Faraday shielding, such as EMP-resistant solar panels, hard drives, and communication devices. Some examples of EMP-hardened equipment include the BCI (Ballistic Capsule Industries) EMP shielded solar panel, which can withstand up to 200 kV/m of electromagnetic radiation, and the Hardened Electronics System (HES) from Hardened Electronics Inc., which can operate at temperatures up to 200°C and withstand EMP attacks.

Creating a Faraday Cage

A Faraday cage is a simple and cost-effective way to protect electronics from EMP. To create a Faraday cage, wrap your device in multiple layers of aluminum foil, with each layer overlapping by 2-3 inches. You can also use a metal mesh screen or a shielded bag. Make sure to seal all openings and connections with tape or wire to prevent electromagnetic radiation from entering or escaping. A typical Faraday cage can protect devices from EMP pulses up to 100 kV/m.

Storing Electronics in Metal Containers or Buildings

Storing electronics in metal containers or buildings can also provide protection from EMP. Look for buildings with thick, non-porous walls and roofs, such as those made of concrete or steel. When storing electronics, use containers made of metal or a metal-lined plastic bag, and make sure to seal all openings and connections. A metal container or building can provide protection from EMP pulses up to 200 kV/m.
