When the computer is turned on, the mercury revaporizes. This cycle of metallic mercury collecting and vaporizing from computers has been seen in several incidents in schools. Metallic mercury is used in a variety of household and industrial items including thermostats, fluorescent light bulbs, barometers, glass thermometers, and some blood pressure machines. Care must be taken in handling and disposing of all items in the home that contain metallic mercury. First, do NOT try to vacuum or heat the metallic mercury in any way.
Mercury vapors are very dangerous and are virtually undetectable.
Avoid breathing mercury dust, vapor, mist, or gas. Avoid contact with eyes, skin, and clothing. If you feel you have been exposed directly to metallic mercury, wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Provide as much clean air as possible.
