That'd be good for being "safe" from fire for 30 minutes, but I wouldn't think it "safe" from anyone with a common screwdriver (i.e., safe from burglary). In other words, it isn't really a "fire safe" but a "fire chest" if you will. But if all he wants is fire protection, it's a viable choice.
Some of these have places on the bottom you can drill holes through to bolt it down, but still, the locks are easily pried open.
But for simple fire protection of things, they would be good. In fact, I have a "fire safe" myself but it is inside a Class B safe that has no fire rating (it's just a burglary safe) and the "fire safe" contains important documents, checkbook/checks, etc.
That's one thing you can do: Buy a Class B rated safe -- since most "fire safes" I've seen (talking about the bigger ones with the metal shells and the "plastic" interiors and usually electronic locks, 1-3 cubic feet in capacity) aren't that burglar-resistant -- and get some of these "fire safes" (chests) to put in it...you definitely get more serious burglar resistance and at least SOME fire protection and come out cheaper than getting a more expensive Class BF rated safe.
My Liberty Presidential floor "safe" (RSC) is in another state -- didn't want it down here as it's a pain to move at almost 1000 pounds -- but I got a small Cobalt (S852C) Class-B safe AND a small Sentry 2300 "fire safe" to go in it.
That'll do for now...
