Gun Safe in Basement?

I purchased a Field & Stream gun safe recently and plan on installing it in my basement. Our home is newer construction, so the basement never seems humid or smells musty. My question is this - if I install the safe in direct contact with the foundation and wall, do I need to worry about the safe drawing moisture from it? I'd hate to drop $$ on a safe only to see it (potentially) rust.

 

You could put thin plastic spacer between the safe and floor. Run the bolt through them both and you are covered.

 

Run a dehumidifier in the basement itself, run a dehumidifier rod in the safe. I would also raise up the safe a few inches off the ground just incase of a pipe burst or sump pump failure.

 

^this. I wouldn't put a steel safe in direct contact with any concrete surface. A simple bond breaker would do the trick. Also, Home Depot, Lowes and just about any other hardware store will sell these containers that have a salt substance in them that absorbs moisture very well. I would put one of those in close proximity to your safe initially to see how much moisture you really have seeping through your basement walls and floor.
