Condenser tubing (popping out of a sink) was responsible for our Stockroom "Flood of '06". The unit was left on in a teaching lab on the 4th floor and by morning it had rained down through our stockroom to collect 2" of water in the first floor classrooms. Mind you this was flowing over wooden shelving not secured to the floor or ceiling and holding unsegregated chemicals. Fortunately, the shelving did not fail or the students would have been entering classrooms that morning likely containing a toxic chemical soup.

On the upside, money was magically available for a beautiful stockroom renovation! :-)

I wish that I did have pictures for you, but I was new to the world of chemical management, etc. and did not know to document everything.

Hi All:

I have a couple of hold-outs who insist on using one-pass water in reflux condensers and the like. The ??California is in constant drought?? argument gets me nowhere.

So I??m looking for flooding incidents when the tubing popped off the condenser and flooded the lab or building, etc. Images would be awesome.

We, the willing, led by the unknowing, are doing the impossible for the ungrateful. We have done so much, for so long, with so little, we are now qualified to do everything with nothing. Teresa Arnold paraphrased from Konstantin Josef Jire?ek (1854 ?? 1918)
