O.k. accidents will happen, we are all human. Rather than make up additional
things to do to reagents,ie; color coding, always "Read the label" every
single time. We do NOT work in an industry where if you overlook something
as important as using correct reagents that there is not a huge price to
pay.  We are talking about peoples lives here.  A mistake as big as this one
and the ramifications involved... it cannot be emphasized enough how
important it is to READ the LABEL.

Hi there,
One of the labs. where I work part-time has a good system ,containers are
colour
coded with a large area of bright paint e.g. alc./red;xylol/blue. Seems to
work
well.
Cheers,Lorraine.
