This seems exceedingly unhealthy.... 145 tons of mercury in pools in the 
basement. Not that I don't deal with mercury at home, but fairly well 
contained and giving me readings in mm Hg as I go to work or come home.

Mineral oil seems more healthy. Not to speak of active systems.

Merry Christmas.
