Well I would say wash it off or at least wipe it down with a damp cloth. if you do get juice on any body parts i.e finger lips etc I would advice rinsing.
I know its only a little juice and it won't kill you, but it is nicotine at its "fullest" and could make you a little sick especially if you combine it with vaping as well.
I know I got juice on my tongue once and had a tingling feeling for a short time.
I am not sure its is so dangerous that you have to be in a protective suite will refilling, but it never hurts to spend the extra seconds and be cautious.
