I am looking at gun safes and also those for home use. I have a question that I hope someone can answer for me concerning the fire ratings. If a safe has a fire rating of 1200 deg for 30 minutes, how much damage will the contents suffer in 1 hour? what I'm really asking is it worth the extra cost for one that is rated 1400 deg for 70 minutes vs one rated 1200 deg for 30 minutes? Would guns be damaged badly by the over extended time in a fire? How about a gun safe vs a household safe? I'm thinking about buying a safe that I can keep both guns and important documents in. Thanks for any advice. Rick
