Mercury vapor is odorless, colorless and very toxic. Even though liquid mercury evaporates slowly, a significant amount of mercury vapor can build up indoors after mercury is spilled, and it can be dangerous to breathe these mercury vapors.
Exposure to mercury can occur when people handle or play with the liquid metal, or when a measuring device breaks and mercury beads scatter onto floors or other surfaces. Spilled mercury is very hard to clean up, especially if it rolls into cracks and crevices, or if it is on fabric, upholstery or other porous material.n general, you can clean up a small mercury spill yourself, such as from a fever thermometer or thermostat.
