Horrible mental images are good for you.
If you pick up an item like a chain saw and say "This sure would make a mess of my hand if I tried to stop it with my fingers" instead of "stop it with my hands cool idea" then you don't need no stinking labels.
*shrug*
When I was a kid, very few items had "warning labels".
In spite of being a little ridge-running hellcat, somehow I managed to survive with all the parts God originally gave me.
