If you don't, it is a good idea to check your chemical inventory to get a handle on the quantity of this highly toxic material stored in your lab.
Metallic mercury is highly toxic by skin absorption, inhalation, and ingestion.
Inorganic and organic mercury compounds are also highly toxic by skin absorption, inhalation, and ingestion. Astute readers will recall the Dartmouth researcher who died following a brief exposure to methyl mercury. The researcher spilled no more than 0.5ml of the compound on her latex-gloved hand. The methyl mercury instantaneously penetrated her glove, was absorbed through the skin, and eventually caused irreversible neurological damage and ultimately death. With all of the hazards associated with mercury, it is prudent laboratory practice to minimize any stocks of mercury and mercury compounds.
