Disposer is safer than you think.

It's not like a blender. I often find construction debris in units subject to recent renovation. Just found six plastic candy wrappers in another. Things can rattle around in the lower chamber too. A whole carrot or a bunch of ice usually clears it out. Most clogs are caused by not running the water for 15 seconds after the grinding is done. Although it's best not to ever put too much in them: especially vegetable peelings.
