We're not talking about a chainsaw, a lathe, or a tool that requires a certain amount of strength or non-intuitive understanding. Safe usage of a soldering iron is safety glasses, not breathing the (fairly irritating) smoke, and not touching the hot end. It is about as dangerous as a screwdriver or a hammer.

Although, like those other tools, having someone skilled show you the ropes is a great benefit. There are lots of ways to solder incorrectly without burning yourself.

I think I was about 10 when my grandfather taught me to solder. I think the safety level really depends on the kid, and a little early-on guidance.
