The unit in question is an Elecraft XG3 test signal generator. It puts out anywhere from -107 dBm to 0 dBm. Is it safe to have these signal generators on and transmitting while not connected to anything, or should they always be connected to a 50 ohm load?
I want to fire it up for the first time but I don't want it hooked up to my actual rig until I know everything's good. Can I just hook it up to a dummy load? Or is the power so minuscule that it doesn't matter?

It's not necessary to turn it off while it is not connected. Zero dBm is a power level of only 1 milliwatt, and no device will be damaged by that power level.
If it were, the manual would have said so.
