I honestly don't know but I thought cash drawers had to be fireproof too. Even if cash burnt up there I am sure it is all accounted for and info stored on servers off site. I don't think that is a major concern. The bank is already opening up in a temp location that was a credit union so the building is already equipped for banking. That is a good thing. Nobody is losing jobs or any valuables and everyone's accounts are safe. The only loss comes to the bank for having to rebuild the branch building and I'm sure their insurance will cover a big chunk of that cost.
