I don't know the answer, but it is still a good question. I'm sure they probably looked at this in the design stages, but you never know. Something could always fall through the cracks.

A basic part of machine control is examining the response of the machine, in each state, to both expected and unexpected inputs. The problem is you can only test those inputs you think of. From my limited experience, machine operators are very creative when developing unexpected inputs. Much more creative than I am in trying to anticipate them.

Of course the next question is:

If they haven't tested for this, who volunteers to be the test pilot to try the experiment? Before you answer, remember that that clothes you are wearing could be all that's between you and good case of what an EMT friend years ago called "Honda Rash".

Kevlar anyone?
