Not sure, but they are metal. My readings into the matter - very limited- indicate that a metal trash can fully lined with cardboard will emp proof electronic stuff.

The metal trash will help, if the lid fits very tightly and no other gaps/holes exist. Lining the inside of a metal can with cardboard will offer no additional protection. Fully covering electronics inside with heavy aluminum foil will offer considerable additional protection however.
EMP (electro magnetic pulse) induces an electrical current in electronic circuits and exposed unprotected wiring that in some cases is strong enough to burn them out.
You protect devices by shielding them completely with something capable of conducting electrical current, like heavy aluminum or copper sheeting/foil. This metal shielding shorts out the EMP wave (in layman's terms), before it can get to your critical electronics.

Thanks - I’ve read that too about trash cans being effective EMP barriers. If computer component is properly wrapped in foil, and then put in a bank box, it could protect it from EMP.... but certainly would provide back up in a place away from the home in the event of fire or other calamity.
