Gun safes and dehumifiers: How many is enough?

[jlr1962]

Once upon a time, the previous home owner of my home had a humidifier. After removing the humidifier, they left the 1/4" copper water line that went to it, curled up in the attic behind a duct out of sight. Two years ago, it got down to 9° two nights in a row. The day after that, we came home to water dripping from the ceiling, fixtures, and vents. LOTS of damage. The copper line had burst.

Yes, that pretty much sums things up.

Right on! Is there a general spread (or low/high) of acceptable temperature and relative humidity that a safe is supposed to be at?

Another question: If the humidity in a safe is very dry, say in the 20-30 relative humidity range, a Golden Rod or Eva-Dry isn't going to help, no? Those products work when one wants to lower the humidity in a safe, correct?

But if the humidity in a safe is already very low (thus dry), how would one raise the RH to fall in the 50RH range?

Does this makes sense?

Don't worry about wanting to raise the humidity if the air in your house or outside is the same as what's in the safe.

What is the humidity in the room with the safe?

The range of 38%-50% should be fine. 38% is not dry enough to crack maintained wood stocks.
