Is there a safe way to remove items that have fallen into a Garbage Disposal?
Circuitry can't just turn itself on; the machine is controlled by a switch. 

If the switch is not flipped on, the circuit is not complete and the machine will not run. 

Our switch is up on the wall, under a cabinet. There is no chance of something hitting that switch accidentally, so I just reach in when something falls down the drain. 

If I thought there was even a chance that the disposal could turn on, I would never reach in there.
