Many people have containers of elemental mercury in their homes left over from science projects or other sources. Elemental mercury is a shiny, silver-gray metal that is liquid at room temperature. If you have elemental mercury in your home, you need to exercise extreme caution with it and package it to prevent any leaks or spills.
Packaging Mercury for Storage and Transportation
All mercury-containing products or containers of mercury should be placed inside a larger container with a tight fitting lid.
Kitty litter or oil-absorbent matter should be placed around the product to protect it from breaking or sudden shocks.
Clearly label storage container as "Mercury - DO NOT OPEN."
Transport container to a household hazardous collection center in a cardboard box. Secure them so that they do not tip over. This will minimize shifting or sliding during sudden stops or turns.
Transport containers in the back of a pick-up truck or in a car trunk. If you must transport in the passenger compartment, make sure there is adequate ventilation.
