Would it work? Maybe, to an extent (with a bunch of theoretical caveats and such).ĭid you tape all the corners, edges, to make it all conductive together? Then there’s the issue of the door edge perimeter gap. You could keep your Safe (with its electronic keypad) inside this room (along with other electronic ‘stuff’). Then put a carpet or plywood on the floor to insulate. Line the walls, ceiling and floor (and door) with conductive material (more Mylar?) or fine metal screen mesh. Maybe it’s tinfoil hat theory, but maybe not… You might theoretically transform one of your closets to be EMP resistant. How heavy is that safe?Īll this sounds like quite a pain in the arse! EMP proof Closet? Sounds pretty ‘cheesy’.īefore covering with your makeshift Mylar Faraday bag, you might first cover the safe with a blanket to electrically insulate the safe itself from the conductive material. Maybe cut them up, overlap edges and tape them together to form a bag sufficient to cover the safe. You know, those so called “space blankets” made of Mylar foil. Maybe one could be made from “Emergency blankets”. The problem for starters is this: the bag might have to be pretty big… I’m not aware of ‘garbage bag’ sized Mylar bags. That is, cover the entire safe with some sort of Mylar conductive foil bag. The reader question mentioned Anti-static bag material. Are you going to scratch off all that paint on your pretty safe, just in case? Anti-static Bag ![]() The tape would need to be in conductive contact with the metal itself around the perimeter of the keypad. It will receive whatever ‘zap’ exists at that location during EMP.Įven if you cover up the keypad with conductive tape or mesh, there’s a problem… The safe is covered with paint or epoxy/enamel of some sort. Depending on door design (gap dimension, folds) and EMP frequency bandwidth (wavelengths), some of the field strength may get in.Ī electronic keypad is entirely exposed on the front surface. If the safe is not entirely made of conductive metal, the EMP will get in.Īdditionally, they have doors and therefore a gap around the perimeter. However I will offer a general opinion about the Safe and its Keypad… However there are factors such as strength of field, attenuation, and the electronic device itself. When we start talking about this, it gets technical (beyond the scope of this article). A conductive skin (or small enough mesh) enclosure which would theoretically protect electronic contents inside (with enough dB attenuation at affected frequencies). One accepted exception to this is the concept of a Faraday cage. Related: Nuclear EMP Components E1, E2, E3, and what they mean… Wow! There are caveats to that, however one might presume 50 KV may likely ‘fry’ electronic circuits! Even electronics not connected to the grid (a safe’s keypad) will receive a charged field jolt (again, with theoretical caveats). ![]() Theoretically a nuclear EMP (electromagnetic pulse) at altitude may zap the atmosphere with up to 50,000 volts per square meter. Remove the power source or damage the electronics within the keypad and you’re locked out (although some also have a physical key lock mechanism for backup functionality – important!). Why? Because they all need a power source and they all have ‘electronics’ inside which could ‘break’. I would suspect that yes, the electronic locking mechanism of a safe will be at risk during a EMP event.Īlthough electronic locking mechanisms can be really convenient, they also cause me concern. So my question is would this work? Or would the metal of the safe channel the pulse into the backside of the keypad and fry it anyway? Is anything kept inside a gun safe also proofed against an EMP? I would think it is, but curious. I think they are like Anti-static bags you get computer parts in. But I have also seen some EMP protection bags which I thought if you sealed over the keypad would accomplish the same thing. I was looking to place some sort of protection over the keypad and have seen an article that a cage resting over it may be of some protection. I just can’t get it out of my head that this will be a epic disaster if an EMP hits. In a moment of stupidity I bought a gun safe with a electronic lock instead of a dial lock. Saw some articles on EMP (my biggest fear). Awhile ago I received this question from a reader:
