[Histonet] Formalin on skin

I am reminded of a story that my son told me from his college days.  He
majored in Chemistry and went on to get a M.S. in Chemical engineering. 
On the first day of his second year Organic Chemistry Laboratory the T.A.
was giving the class the basic ground rules and safety procedures for
their laboratory sessions.  The one thing that stuck in his mind is when
the T.A. explained what they would be dealing with on this level.

"Up until now, in your Freshman labs, and any labs that you may have had
prior in High school, the chemicals that you have handled could hurt you. 
The chemicals that you will be dealing with throughout the course of this
lab can KILL you."

He never forgot that, as did all of his class mates, for the rest of the
semester,and thankfully so.  They are all still with us today.
