Hi Ron;

I was just wondering if you have any documentation regarding the reaction
products that are formed when you add bleach to DAB.  If my memory serves me,
I believe that you may still be dumping potential carcinogens down the
drain.  Just
because the solution changes colour does not mean it becomes harmless.  I
wonder if John Keirnan has ever looked at this question; how about it John.
