Image via WikipediaI recently saw the movie at the Deer Park IMAX theather in 3D, with my family. It was a visually stunning movie and the storyline was excellant and very different from the one most of us are familar with. The CDC NIOSH science blog discusses the occupational issues that led to the term Mad as a hatter hence leading to Johnny Depp's character in the movie. What was the occupational safety and health issue? Well most people probably know by now that it was mercury exposure or mercury poisoning. Hatters used mercury to change fur into felt. Since these areas were poorly ventilated the exposure levels must have been tremendous.
