Mercury is a silvery, mobile, odorless liquid
Mercury is used as a catalyst, in dental
applications; and in pharmaceuticals; as a liquid cathode in
cells for the electrolytic production of caustic and chlorine.
It is used in electrical apparatus (lamps, rectifiers, and batteries) and in control instruments (switches, thermometers,
and barometers)
UN2809 Mercury, Hazard class: 8; Labels:
8-Corrosive material, 6.1-Poisonous material
Heating mercury causes the formation of
toxic mercury oxide fumes. Reacts violently with alkali
metals; acetylene, azides, ammonia gas; chlorine, chlorine
dioxide; many acids; most metals; ground mixtures of
sodium carbide, and ethylene oxide. Contact with methyl
azide forms shock- and spark-sensitive explosives. Attacks
copper and many other metals, forming amalgams
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform to EPA regulations governing
storage, transportation, treatment, and waste disposal.
Accumulate for purification and re-use if possible. Mercury
vapors may be adsorbed or treated with sulfide solutions
and then sent to mercury recovery operations
