Is the antistatic bag that a hard drive comes packaged in a Faraday cage? Is it capable of shielding electronic devices against an EMP pulseWould these bags be useful to package small electronics in in case of an EMP attack?
attempt to align the holes into mortar particularly than the brickMark each and every of the holes with the shelf point with an eternal markerFrom a ironmongery keep, acquire lead anchors, as properly because of the fact the screws that extra healthful into itthe burden on the shelf would be certain the scale and frequency of the anchorsutilising a masonary bit, drill holes of length as prescribed for lead anchorsUse a reliable epoxy and positioned the anchor in, doing so rapidly because of the fact the adhesive dries speedy.Then carry the shelf up andpersistent the screws inthis gadget won't injury the mortar and is amazingly reliable, yet will of path depart anchors at the back of in case you do away with the shelf laterThe anchors are silver/gray, however, so as that they don't seem to be that seenThe blue Tapcon? fastners paintings properly in concrete, yet not so properly in brick because of the fact the stone oftentimes cracks.
The antistatic bag is not precisely a Farady cage, but it is close enough (the only difference being that a Farady cage has holes, while an antistatic bag does not; they both use the skin effect to protect things from electromagnetics)It will protect an electronic device against some EMPs, but the magnitude of the pulse that it can protect against is limited by the thickness of the conductive layer in the bagI would not expect that the strongest EMPs would be stopped by a small antistatic bag, but it will be a whole lot better protection against EMPs than just about anything you are likely to already have lying aroundIf you are really worried, though, you could get the same effect with a layer or two of aluminum foil, most likely.
try a resin made for this purpose this resin will allow you to join on to concrete great stuff .
No offense; but I suspect my concern would be first to remediate the walls; long before I decided to add further stress to them.
I run vertical 4X4's down the walls and made sure these were affixed good, then attached the shelves.
