While I don't anticipate any problems, humans are often excitable and I've found this can create difficulties in communication.
Screaming “Oh, my god! It has a chainsaw! Ahh! Ahh! Ahh!” in a high pitched voice is hard to decipher and unclear in intent.
Should a similar situation occur, clearly annunciate in a normal voice “We have lost control. Please activate the failsafes in order to prevent further loss of internal organs.” This will provide for faster response in the case of an emergency.
