If a household hazardous waste collection event or facility is not available, small household thermometers may be disposed of in the regular trash. This is the least-preferred disposal option, but it may be the only option available in some areas.
Thermometers should be placed in a strong plastic zip top bag and wrapped in several layers of newspaper. The wrapped newspaper should be sealed with strong tape and placed in the trash.
Spill Cleanup Guidance
These procedures are intended for small devices like thermometers or thermostats from households only. Contact your local health department or a hazardous waste disposal company for assistance in disposing of larger quantities of liquid mercury.
