I would never tell my students to ignore any safety data sheet, nor would I
telll tham that any substance is absolutely safe.   The first thing I
taught students was that you should treat alll chemicals with respect, even
sand.  Even air and water can kill you.  As Paracelsus said, "Everything is
a poison, the difference is in the dose."   Not all substances require the
same level of caution, which is why you use the SDS to determine what to be
most careful of.  

As an aside, if you never teach your students that ether
acn produce explosive peroxides, and they are injured in a peroxide
explosion, does that create a legal liability or must a moral one?
