First, empty the safe. A friend of mine has a HUGE noise maker safe (he also lives across the street from BLM land so he can go make noise just about any time he wants to). It's in his garage, but not where it needs to be. We talked about the weight of the contents vs. the weight of the safe. He figures the contents are about 1/3 of the total. Neither one of us could get it to tip even a little fully loaded. He'll probably have to hire somebody to help him.

I would also recommend professionals to, at the very least, load and unload it.
