Hello, I need advice about how to treat spilled mercury. A friend of mine is going to do an experiment about barometers, and she needs some mercury. I am worried about any accident. As you know, mercury vapors are very toxic for nervous system. Any advice is welcomed. I will immediately do a Google search as soon as I post this thread. Thank you. P.S. The Google searching gave me this info: "Use vacuum cleaner or sponge to suck off any spilled mercury. If it is spilled in a trace amount, just add some elemental sulfur onto it, and this will convert mercuric sulfide, a less harmful compound". Any suggestions?
