The heating elements in a modern electric oven are constructed in a similar fashion as the burners on a conventional elec range top. The actual current carrying wire, coil or ribbon is not exposed to the outside world, but housed within an insulated sheathing just for this reason, commonly ceramic. This is not the case with many small appliances like a toaster where what you see is the actual conducting wire, and we all know what happens when one sticks a fork in there to free a stuck bagel while it is on.
Having said that, the small print disclaimer is that it is not impossible, just incredibly rare, for a set of circumstances to occur that leads to an unfortunate baker completing a circuit. If you happened to break the oven light bulb while on or smashed the element with the alum peel that could leave a nasty mark or worse. Otherwise it takes a bizzaro chain of issues or defect to create an elec hazard. But lacking a "perfect storm" scenario modern elec ovens, properly working, in a properly grounded and wired home, are considered quite safe in this regard. If you have a bad feeling about it, or like me one of your nicknames includes the word "clumsy", a wooden peel might be the way to go.
