Mercury Thermometers & Thermostats

Mercury Thermometers & ThermostatsMercury Thermometers & Thermostats

Mercury is one of the most toxic metals found in the home. Mercury may be harmful if inhaled, swallowed, or touched. The risk to animals and the environment is great, too. One broken thermometer may release enough mercury to contaminate a small lake. Mercury spilled from a broken thermometer is serious business - it can harm your family if not cleaned up properly and immediately.

In Minnesota, it is illegal to throw away a mercury thermometer or a mercury thermostat because they are hazardous - never put them in your garbage, whether it is intact or broken. Take mercury thermometers and thermostats to your county's household hazardous waste collection site. To find the collection site nearest you, go to the Household Hazardous Waste page.

Mercury in Fish

Once released into our air and water, mercury can end up in the fish we eat. To learn how you can reduce your exposure to mercury (and other contaminants) when eating fish, visit the Minnesota Department of Health website.

Alternatives to Mercury Thermometers & Thermostats

Disposal Information

Follow these guidelines to dispose of a mercury thermometer:
  • Identify the type of thermometer. A mercury thermometer is made of glass and contains a silver, metallic gray or black liquid.
  • Transport a mercury thermometer in a rigid, sealed container like a small plastic food container to avoid breakage on the way to the collection site.
  • Alcohol thermometers - those containing red liquid - are OK to throw in the garbage.


See the Rethink Recycling advice on properly disposing of other household products containing mercury, such as fluorescent bulbs, certain types of batteries and electronic products.

 

For information on proper disposal of mercury or items that contain mercury, including mercury thermometers, contact your county.
