The discussion regarding the repair and maintenance of mercury
barometers is very interesting, and the discussion regarding safe
handling of mercury is especially so.
What is the best method to clean up spilled mercury? A chemist
suggested to me that I sprinkle powdered sulfur over the spilled
mercury. The sulfur and mercury react to form mercurous sulfide which
can be swept up with a broom. Does anyone else have any other ideas?
One method NOT to use is a vacuum cleaner. Believe it or not, several
years ago a homeowner in Illinois tried to clean up spilled mercury
using the household vacuum cleaner. Mercury vapors were blown out the
exhaust contaminating the house. Illinois EPA was eventually called
in. The house had to be demolished.
Thanks.
