Elemental or metallic mercury is a potent neurotoxin, even with small exposures. Avoid exposure by replacing broken thermometers and lamps, and use a spill kit to manage a spill clean-up.
Mercury is a liquid at room temperature and readily evaporates into the air. People can be exposed if instruments or equipment containing mercury break and release mercury-containing dust, liquid or vapor. Health effects can include central nervous system disorders, reproductive effects and kidney damage.
