Who is Richard Lippold, the famous artist?
Apart from the obvious (don't spill boiling water on yourself; don't get it in your eye) I can't think of any. Just because it's (shock, horror) SCIENCE, that doesn't in this case make it any more dangerous than what you do every day in the kitchen. The correct answer may include safety goggles, tongs depending. Sometimes, you just have to give the teacher back what you've been told.
