Mercury Thermometers & Thermostats

Items containing mercury should be taken to a Household Hazardous Waste drop-off site.

How to Clean Up Spilled Mercury:

  • Do not use a vacuum or broom and do not touch.  Keep all people and pets away. Minimize harmful vapors by turning off fans & heaters.

  • Wearing gloves, scoop up the mercury using an index card or stiff paper edge. Place it in a zip lock bag or airtight container. Use a flashlight to locate small mercury beads, which can be removed using an eye dropper or sponge. If it spills on a rug, cut out the contaminated piece and bag it. Dispose of all clean-up materials along with the mercury in the zip lock bag. Take it to a Hazardous Waste collection site. 

  • For a larger spill, call: Spill Report Line 1-800-943-0003
