Mixing of chemicals for disposal
Content-Type: text/plain; charset="US-ASCII"
Mixing of chemicals before disposal seems to me to be a hazardous and
counterproductive thing to do.
It seems to me that we're dealing here with an irreducible conflict between
scientific and management views of the nature of matter. Scientifically, the
stuff continues to be reactive and hazardous when it's mixed. From a
management viewpoint, if I understand aright, once it's labeled "waste" it
undergoes transubstantiation into a form no longer hazardous as long as it's
disposed of according to ritual. - I've seen this uncontrolled mixing go on
in at least two labs, and was reassured both times by managers that it was
all right because it was designated waste.
Just an observation from an old pathologist with no management training.

We have always combined all of our wastes. The company that hauls our waste
is aware of the combinations and has no problem with it. The company we
used prior was the same. We do not add any reagents containing picric acid
to this mixture. These are taken separately.
