I believe that temperature and humidity will be OK but I would keep an eye on it. I keep a dehumidifier next to my safe in the basement and keep the humidity near the safe at less than 45%.

You could also contact Cortec Corporation in St. Paul, MN. 651-429-1122. They make vapor phase corrosion inhibitors that I have used in other industries. I believe they have inhibitors that can be used in safes and corrosion inhibitor bags designed for military weapons.
