Larry, MEK is very nasty stuff, does get through the skin.

Jim: I don't believe it is the MEK that is so toxic. I was an organic
chemist for many years. MEK evaporates very quickly and doesn't get
past your skin surface. MEK which may have toluene in it is a different
story. Yes aromatic benzene/toluene is quite toxic.
