Thermometers
Items that contain Mercury

Mercury is very hazardous!!! 

Any items that have mercury in them must be disposed of at our Household Hazardous Waste event. 

Please check out our Upcoming Events page to see if we have scheduled our next one yet. This event is held every other year. 

If you'd like a few more details on Hazardous Chemicals, head over here.

​Thermostats

Johnstone Supply will accept these for disposal! 
​They have a free drop off box.
​Thermostats cannot be thrown away in the garbage because of the Mercury.
