What to Do if a Mercury Thermometer Breaks?

Evacuate the area, making sure that no one walks through the mercury. Make sure to evacuate pets as well. Open all windows and doors to the outside and close all doors to other parts of the house. Do not allow children to help with the clean up.

What to do:

  • Assemble cleanup supplies. These include disposable gloves, an eyedropper, two stiff pieces of paper or cardboard, two plastic bags, duct tape, a flashlight and a wide-mouth container. What you will use for cleanup will need to be disposed of with the mercury.
  • Remove watches and jewelry. Mercury will bond to metal. Wear gloves for protection.
  • Clean the spill. First remove watches and jewelry because mercury will bond to metal. Wear disposable gloves for protection.
  • On hard surfaces: Mercury can be cleaned up easily from hard surfaces. Use a flashlight to find the loose mercury beads. Gently scoop the mercury together and lift the beads into the wide-mouth jar with the stiff paper. Pick up remaining mercury with sticky tape and place contaminated tape in a plastic bag along with the eyedropper, stiff paper, and gloves. Put that bag into another plastic bag. Seal and label the bag as mercury waste. Place this bag and sealed container in the second bag. Label it as mercury waste and call your State agency for appropriate disposal.
  • On absorbent surfaces: If a spill occurs on carpet, curtains, upholstery or another absorbent surface, the mercury-contaminated section should be cut out. This cut-out section, along with all cleanup items, should be placed in a plastic bag. Label it as mercury waste and call your State agency for appropriate disposal.
  • In water: Mercury will sink to the bottom. Gently remove as much water as possible and recover the mercury with an eyedropper and put it in a wide-mouth container. Close the lid, seal with tape, label the jar and call your State agency for disposal instructions.
  • In a drain: Mercury will get caught in the sink trap. Working over a tray, remove the trap and pour the contents into a wide-mouth container. Close the lid and seal with tape. Contact your State agency for disposal instructions.
  • Be informed: For more information about Mercury visit the Environmental Protection Agency.
