I'll bring some gloves for sure. Its already in a sealed container for
storage, so it should be cool there. Rameen - I believe its only an irritant
(so if you step into a vapor of it, it'll burn your eyes and nose like mad).
Plus, given that the boiling point of the acid is so high, its unlikely that
you should ever inhale much of it without trying reeeeaaaally hard to do so
:).
