Remember the brass pump-type fire extinguishers from the 40's and 50's? Those things used carbon tet as their fire suppression fluid. It was also a favorite thread tapping lubricant around the shop where I grew up, and we also used if for cleaning voltage regulator points and other electrical stuff. It was not until years later that we learned it's a carcinogen, among other nasty side effects.
