I find a lot of the comments on this almost humorus,
I spent many years in the instrumentation and control field,
one project back in the 80's early 90's was the removal from service of numerous differential pressure meters both recorders and transmitters,
that employed mercury filled bellows as sensing elements and many of them came out of water systems. Prior to removing them they had required being flushed and cleaned because the operators would not operate the valving correctly and would blow the mercury out and into the process fluid. We used to routinely clean and reuse the mercury in those meters and then add to it during calibration and servicing. When we took those meters out of service we recovered hundred of pounds of mercury.
Also many of our manometers were mercury filled, some were scaled in inchs of hg many had conversion scales on them to read in inches of water using mercury as a fill fluid.
When all the OSHA mercury exposure standards got shoved down our throats $100,000 of dollars of calibration standards and labs and shops had to be trashed and sent of to haz mat land fills.
