Elemental mercury is extremely hazardous due to its toxicity, and mercury in other forms may also designate as hazardous. Mercury is found in electrical switches and relays; thermostats; fluorescent tubes and high intensity discharge lamps; dental amalgam; batteries; measuring instruments (barometers, thermometers, etc.); pharmaceuticals; paint produced before 1992; and laboratory and medical equipment. Items or compounds containing mercury should not be put in the garbage or poured down the drain. Mercury should be reclaimed through a reclamation facility licensed for this purpose. You can send mercury-containing items or compounds directly to a mercury reclamation facility or hire a broker to ship the waste to a reclaimer(See Hazardous Waste Disposal). If you hire a broker, check that the mercury-containing item goes to a licensed mercury reclamation facility.
